[[File:Crossbow TenPoint Stealth SS.png|thumb|21st-century hunting compound crossbow|upright=1.3]]

A '''crossbow''' is a ranged weapon using an [[Elasticity (physics)|elastic]] launching device consisting of a [[Bow and arrow|bow]]-like assembly called a ''prod'', mounted horizontally on a main frame called a ''tiller'', which is hand-held in a similar fashion to the [[stock (firearms)|stock]] of a [[long gun]]. Crossbows shoot [[arrow]]-like [[projectile]]s called ''[[crossbow bolt|bolts]]'' or ''quarrels''. A person who shoots crossbow is called a ''crossbowman'', an ''arbalister'' or an ''[[arbalist (crossbowman)|arbalist]]'' (after the [[arbalest]], a European crossbow variant used during the 12th century).{{sfn|Loades|2018}}

Crossbows and bows use the same elastic launch principles, but differ in that an archer using a [[Bow and arrow|bow]] must draw-and-shoot in a quick and smooth motion with limited or no time for aiming, while a crossbow's design allows it to be spanned and cocked ready for use at a later time and thus affording them unlimited time to aim. When shooting bows, the archer must fully perform the [[bow draw|draw]], holding the string and arrow using various techniques while pulling it back with arm and back muscles, and then either immediately shooting instinctively without a period of aiming, or holding that [[form (exercise)|form]] while aiming. Both demand some [[physical strength]] to do so using bows suitable for warfare, though this is easier using lighter [[Glossary of archery terms#D|draw-weight]] hunting bows. As such, their accurate and sustained use in warfare takes much practice.

Crossbows avoid these potential problems by having trigger-released cocking mechanisms to maintain the tension on the string once it has been '''spanned''' – drawn – into its ready-to-shoot position, allowing these weapons to be carried cocked and ready and affording their users time to aim them. This also allows them to be readied by someone assisting their users, so multiple crossbows can be used one after the other while others reload and ready them. Crossbows are spanned into their cocked positions using a number of techniques and devices, some of which are mechanical and employ gear and pulley arrangements – levers, belt hooks, pulleys, windlasses and cranequins – to overcome very high draw weight.<ref>{{Cite web|url=https://todsworkshop.com/blogs/blog/crossbows-spanning-methods|title = Crossbows – Spanning Methods|website=Tod's Workshop}}</ref> These potentially achieve better precision and enable their effective use by less familiarised and trained personnel, whereas the simple and composite warbows of, for example, the English and the steppe nomads require years of training, practice and familiarisation.

These advantages for the crossbow are somewhat offset by the longer time needed to reload a crossbow for further shots, with the crossbows with high draw weights requiring sophisticated systems of gears and pulleys to overcome their huge draw weights that are very slow and rather awkward to employ on the battlefield. Medieval crossbows were also very inefficient, with short shot stroke lengths from the string lock to the release point of their bolts, along with the slower speeds of their steel prods and heavy strings, despite their massive draw weights compared to bows, though modern materials and crossbow designs overcome these shortcomings.

The earliest known crossbows were invented in [[History of Science and Technology in China|ancient China]] in the first millennium BC and brought about a major shift in the role of projectile weaponry in wars, especially during [[Qin's wars of unification|Qin's unification wars]] and later the [[Han-Xiongnu War|Han campaigns against northern nomads]] and [[War of the Heavenly Horses|western states]]. The medieval European crossbow was called by many names, including "crossbow" itself; most of these names derived from the word ''[[ballista]]'', an [[ancient Greek]] torsion [[siege engine]] similar in appearance but different in design principle.<ref>{{Citation |last= Payne-Gallwey |first= Ralph |author-link= Ralph Payne-Gallwey |title= The Crossbow |orig-year= 1903 |year= 2007 |publisher= Skyhorse |isbn= 978-1602390102 |page= 2 }}</ref>

In modern times, [[firearm]]s have largely supplanted bows and crossbows as weapons of war, but crossbows remain widely used for competitive [[shooting sport]]s and hunting, and for relatively silent shooting.<ref>{{Cite web|url=http://digital.outdoornebraska.gov/nebraskaland-magazine/the-rise-of-the-modern-crossbow|title = The Rise of the Modern Crossbow|publisher=Nebraska Game and Parks Commission}}</ref>

== Terminology ==

A crossbowman is sometimes called an ''[[arbalist (crossbowman)|arbalist]]'', or historically an [[wikt:arbalister#Noun|arbalister]]''.

''Arrow'', ''bolt'' and ''quarrel'' are all suitable terms{{sfn|Loades|2018}} for crossbow projectiles, as was ''[[wikt:vire#Middle English|vire]]'' historically.

The ''lath'', also called the ''prod'', is the bow of the crossbow. According to W. F. Peterson, ''prod'' came into usage in the 19th century as a result of mistranslating ''rodd'' in a 16th-century list of crossbow effects.{{sfn|Loades|2018}}

The ''stock'' (a modern term derived from [[stock (firearm)|the equivalent concept in firearms]]) is the wooden body on which the bow is mounted, although the medieval ''tiller'' is also used.{{sfn|Loades|2018}}

The ''lock'' refers to the release mechanism, including the string, sears, trigger lever, and housing.{{sfn|Loades|2018}}

==Construction==

[[File:Noix corde carreau arbalette.svg|thumb|[[Medieval Europe]]an crossbow nut mechanism: {{ordered list|item_style=margin-bottom: 0| Nut| String| Quarrel| Trigger}}]]
[[File:Nuss Armbrust.jpg|thumb|16th century crossbow nut excavated at [[Harburger Schloßstraße]], [[Hamburg-Harburg]], Germany]]

A crossbow is essentially a [[bow (weapon)|bow]] mounted on an elongated frame (called a tiller or stock) with a built-in mechanism that holds the drawn [[bow string]], as well as a [[trigger (firearms)|trigger]] mechanism, which is used to release the string.

=== Chinese vertical trigger lock ===

The Chinese trigger was a mechanism typically composed of three [[Casting (metalworking)|cast]] [[bronze]] pieces housed inside a hollow bronze [[Housing (engineering)|enclosure]]. The entire mechanism is then dropped into a carved slot within the tiller and secured together by two bronze [[Dowel|rods]].{{sfn|Loades|2018}} 

The string catch (nut) is shaped like a "J" because it usually has a tall erect rear spine that protrudes above the housing, which serves the function of both a cocking lever (by pushing the drawn string onto it) and a primitive rear sight. 

It is held stationary against tension by the second piece, which is shaped like a flattened "C" and acts as the [[Sear (firearm)|sear]]. The sear cannot move as it is trapped by the third piece, i.e. the actual trigger blade, which hangs vertically below the enclosure and catches the sear via a notch. 

The two [[bearing surface]]s between the three trigger pieces each offers a [[mechanical advantage]], which allow for handling significant draw weights with a much smaller pull weight. 

During shooting, the user will hold the crossbow at eye level by a [[Pistol grip|vertical handle]] and aim along the arrow using the sighting spine for [[Elevation (ballistics)|elevation]], similar to how a modern [[rifleman]] shoots with [[iron sights]]. 

When the trigger blade is pulled, its notch disengages from the sear and allows the latter to drop downwards, which in turn frees up the nuts to pivot forward and release the bowstring.

{{blockquote|The {{lang|zh-Latn|nu}} ({{lang|zh|弩}}) [crossbow] is so called because it spreads abroad an aura of rage [{{tlit|zh|nù}}] ({{lang|zh|怒}}). Its stock is like the arm of a man, therefore it is called {{lang|zh-Latn|bi}} ({{lang|zh|臂}}). That which hooks the bowstring is called {{lang|zh-Latn|ya}} ({{lang|zh|牙}}), for indeed it is like teeth. The part round about the teeth [i.e. the housing box] is called the {{lang|zh-Latn|guo}} ({{lang|zh|郭}}) ["city wall"], since it surrounds the {{lang|zh-Latn|gui}} ({{lang|zh|規}}) [lug] of the teeth [i.e. the locking nut]. Within [and below] there is the {{lang|zh-Latn|xuan dao}} ({{lang|zh|懸刀}}) ["hanging knife", i.e. the trigger blade] so called because it looks like one. The whole assembly is called {{lang|zh-Latn|ji}} ({{lang|zh|機}})["machine" or "mechanism"], for it is just as ingenious as the [[loom]].{{sfn|Needham|1994|p=133}}|{{lang|zh-Latn|[[Shiming]]}}}}

=== European rolling nut lock ===

The earliest European designs featured a transverse slot in the top surface of the frame, down into which the string was placed. To shoot this design, a vertical rod is thrust up through a hole in the bottom of the notch, forcing the string out. 

This rod is usually attached perpendicular to a rear-facing lever called a ''tickler''. A later design implemented a rolling cylindrical pawl called a ''nut'' to retain the string. This nut has a perpendicular centre slot for the bolt, and an intersecting axial slot for the string, along with a lower face or slot against which the internal trigger sits. 

They often also have some form of strengthening internal ''sear'' or trigger face, usually of metal. These ''roller nuts'' were either free-floating in their close-fitting hole across the stock, tied in with a binding of sinew or other strong cording; or mounted on a metal axle or pins. 

Removable or integral plates of wood, ivory, or metal on the sides of the stock kept the nut in place laterally. Nuts were made of antler, bone, or metal. Bows could be kept taut and ready to shoot for some time with little physical straining, allowing crossbowmen to aim better without fatiguing.

=== Bow ===

Chinese crossbow bows were made of composite material from the start.{{sfn|Loades|2018}}

European crossbows from the 10th to 12th centuries used wood for the bow, also called the ''prod'' or ''lath'', which tended to be [[ash tree|ash]] or [[taxus|yew]].{{sfn|Loades|2018}}

Composite bows started appearing in Europe during the 13th century and could be made from layers of different material, often wood, horn, and sinew glued together and bound with animal tendon. These composite bows made of several layers are much stronger and more efficient in releasing energy than simple wooden bows.{{sfn|Loades|2018}}

As steel became more widely available in Europe around the 14th century, steel prods came into use.{{sfn|Loades|2018}}

Traditionally, the prod was often lashed to the stock with rope, [[whipcord]], or other strong cording. This is called the ''[[bridle]]''.{{sfn|Loades|2018}}

=== Spanning mechanism ===

The Chinese used [[winch]]es for large crossbows mounted on [[fortification]]s or [[wagon]]s, known as "bedded crossbows" (床弩). Winches may have been used for handheld crossbows during the [[Han dynasty]] (202&nbsp;BC – 9&nbsp;AD, 25–220 AD), but there is only one known depiction of it. 

The 11th century Chinese military text ''[[Wujing Zongyao]]'' mentions types of crossbows using winch mechanisms, but it is not known if these were actually handheld crossbows or mounted crossbows.{{sfn|Needham|1994|p=150}} 

Another drawing method involved the shooters sitting on the ground, and using the combined strength of leg, waist, back and arm muscles to help span much heavier crossbows, which were aptly called "waist-spun crossbows" (腰張弩).

During the [[Post-classical history|medieval era]], both Chinese and European crossbows used [[stirrup]]s as well as [[belt hook]]s.{{sfn|Needham|1994|p=150}} 

In the 13th century, European crossbows started using winches, and from the 14th century an assortment of spanning mechanisms such as winch pulleys, cord pulleys, gaffles (such as gaffe levers, goat's foot levers, and rarer internal lever-action mechanisms), cranequins, and even screws.{{sfn|Loades|2018}}<ref>{{cite web|last1=Ixax|first1=belle|title=Crossbow Reviews 2017|url=http://thetagtech.com/best-crossbow-reviews|website=Archer's Café|access-date=9 March 2017}}</ref>

The smallest crossbows are pistol crossbows. Others are simple long stocks with the crossbow mounted on them. These could be shot from under the arm. 

The next step in development was stocks of the shape that would later be used [[Stock (firearms)|for firearms]], which allowed better aiming. The [[arbalest]] was a heavy crossbow that required special systems for pulling the sinew via windlasses. 

For [[siege warfare]], the size of crossbows was further increased to hurl large projectiles, such as rocks, at fortifications. The required crossbows needed a massive base frame and powerful windlass devices.<ref>{{cite book|last=O'Connell|first=Robert L.|date=1989|title=Of Arms and Men: A History of War, Weapons, and Aggression|url=https://archive.org/details/ofarmsmenhisto00ocon|url-access=registration|publisher=[[Oxford University Press]]|isbn=0195053591|page=[https://archive.org/details/ofarmsmenhisto00ocon/page/65 65]}}</ref>

=== Projectiles ===
[[File:Han Bronze Arrows & Lead Pellets (9884175776).jpg|thumb|Arrowheads and lead balls, [[Han dynasty]]]]

The arrow-like projectiles of a crossbow are called [[crossbow bolt|bolts or quarrels]]. These are usually much shorter than arrows but can be several times heavier. 

There is an optimum weight for bolts to achieve maximum kinetic energy, which varies depending on the strength and characteristics of the crossbow, but most could pass through common mail. 

Crossbow bolts can be fitted with a variety of heads, some with sickle-shaped heads to cut rope or rigging; but the most common today is a four-sided point called a [[Quarrel (projectile)|quarrel]]. A highly specialized type of bolt is employed to collect blubber biopsy samples used in biology research.

Even relatively small differences in arrow weight can have a considerable impact on its flight trajectory and drop.<ref name="CrossbowArrowDrop">{{cite web|url=http://www.bestcrossbowsource.com/crossbow-arrow-drop-charted-test-results/|title=Crossbow Arrow Drop – Charted Test Results|access-date=12 July 2019|website=BestCrossbowSource.com|archive-date=31 July 2019|archive-url=https://web.archive.org/web/20190731005020/http://www.bestcrossbowsource.com/crossbow-arrow-drop-charted-test-results/|url-status=dead}}</ref>

[[Bullet-shooting crossbow]]s are modified crossbows that use bullets or stones as projectiles.

The [[Military history of China before 1912#Crossbow|ancient Chinese crossbow]] often included a metal (i.e. bronze or steel) grid serving as [[iron sights]]. Modern crossbow sights often use similar technology to modern firearm sights, such as [[red dot sight]]s and [[telescopic sight]]s. Many crossbow scopes feature multiple [[crosshairs]] to compensate for the significant effects of [[gravity]] over different ranges. In most cases, a newly bought crossbow will need to be sighted for accurate shooting.<ref>{{cite web|url=http://www.bestcrossbowsource.com/how-to-sight-a-crossbow|title=Sighting a Crossbow|work=Best Crossbow Source|access-date=28 October 2014|archive-date=28 October 2014|archive-url=https://web.archive.org/web/20141028114057/http://www.bestcrossbowsource.com/how-to-sight-a-crossbow/|url-status=dead}}</ref>

A major cause of the sound of shooting a crossbow is vibration of various components. Crossbow silencers are multiple components placed on high vibration parts, such as the string and limbs, to dampen vibration and suppress the sound of loosing the bolt.<ref>{{cite web|title=Crossbow|url=http://www.reference.com/browse/crossbow|website=[[reference.com]]|publisher=[[Columbia University Press]]|access-date=1 March 2015|archive-url=https://web.archive.org/web/20150402100105/http://www.reference.com/browse/crossbow|archive-date=2 April 2015}}</ref>

This source refers to the use of a giant crossbow between the 6th and 5th centuries BC, corresponding to the late [[Spring and Autumn period]]. [[Sun Tzu]]'s ''[[The Art of War]]'' (first appearance dated between 500 BC to 300 BC<ref>James Clavell, ''The Art of War'', prelude</ref>) refers to the characteristics and use of crossbows in chapters 5 and 12 respectively,<ref>{{Cite web |url=https://www.gutenberg.org/files/132/132.txt |title=The Art of War, by Sun Tzu |access-date=3 May 2018 |archive-date=4 May 2018 |archive-url=https://web.archive.org/web/20180504124447/http://www.gutenberg.org/files/132/132.txt |url-status=dead }}</ref> and compares a drawn crossbow to "might".{{sfn|Needham|1994|p=34}} The ''[[Huainanzi]]'' advises its readers not to use crossbows in marshland where the surface is soft and it is hard to arm the crossbow with the foot.{{sfn|Needham|1994|p=141}} The ''[[Records of the Grand Historian]]'', completed in 94 BC, mentions that [[Sun Bin]] defeated [[Pang Juan]] by ambushing him with a battalion of crossbowmen at the [[Battle of Maling]] in 342 BC.{{sfn|Needham|1994|p=139}} The ''[[Book of Han]]'', finished 111 AD, lists two military treatises on crossbows.{{sfn|Needham|1994|p=22}}{{sfn|Wright|2001|p=42}}

Handheld crossbows with complex bronze trigger mechanisms have also been found with the [[Terracotta Army]] in the tomb of [[Qin Shi Huang]] (r. 221–210 BC) that are similar to specimens from the subsequent [[Han dynasty]] (202 BC–220 AD), while crossbowmen described in the Qin and Han dynasty learned drill formations, some were even mounted as [[chariots in ancient China|charioteers]] and [[horse archery|cavalry units]], and Han dynasty writers attributed the success of numerous [[Han–Xiongnu War|battles against the Xiongnu]] and [[Western Regions]] city-states to massed crossbow volleys.{{sfn|Needham|1994|pp=124–128}} The bronze triggers were designed in such a way that they were able to store a large amount of energy within the bow when drawn but was easily shot with little resistance and recoil when the trigger was pulled. The trigger nut also had a long vertical spine that could be used like a primitive [[iron sight|rear sight]] for [[elevation (ballistics)|elevation]] adjustment, which allowed precision shooting over longer distances. The Qin and Han dynasty-era crossbow was also an early example of a [[modular design]], as the bronze trigger components were also mass-produced with relative precise [[engineering tolerance|tolerances]] so that the parts were interchangeable between different crossbows. The trigger mechanism from one crossbow can be installed into another simply by dropping into a tiller slot of the same specifications and secured with [[dowel pin]]s. Some crossbow designs were also found to be fitted with bronze buttplates and [[trigger guard]].

It is clear from surviving inventory lists in [[Gansu]] and [[Xinjiang]] that the crossbow was greatly favored by the Han dynasty. For example, in one batch of slips there are only two mentions of bows, but thirty mentions of crossbows.{{sfn|Needham|1994|p=141}} Crossbows were mass-produced in state armories with designs improving as time went on, such as the use of a mulberry wood stock and brass. Such crossbows during the [[Song dynasty|Song Dynasty]] in 1068 AD could pierce a tree at 140 paces.{{sfn|Peers|1996|pp=130–131}} Crossbows were used in numbers as large as 50,000 starting from the Qin dynasty and upwards of several hundred thousand during the Han.{{sfn|Needham|1994|p=143}} According to one authority, the crossbow had become "nothing less than the standard weapon of the Han armies", by the second century BC.{{sfn|Graff|2002|p=22}} Han soldiers were required to arm a crossbow with a draw weight equivalent of {{convert|76|kg|abbr=on}} to qualify as an entry-level crossbowman,{{sfn|Loades|2018}} while it was claimed that a few elite troops were capable of arming crossbows with a draw-weight in excess of {{convert|340|kg|abbr=on}} by the hands-and-feet method.{{sfn|Loades|2018|p=9}}{{sfn|Selby|2000|p=172}}

After the Han dynasty, the crossbow lost favor during the [[Six Dynasties]], until it experienced a mild resurgence during the [[Tang dynasty]], under which the ideal expeditionary army of 20,000 included 2,200 archers and 2,000 crossbowmen.{{sfn|Graff|2002|p=193}} [[Li Jing (Tang dynasty)|Li Jing]] and Li Quan prescribed 20 percent of the infantry to be armed with crossbows.{{sfn|Graff|2016|p=52}}

During the [[Song dynasty]], the crossbow received a huge upsurge in military usage, and often overshadowed the bow 2 to 1 in numbers. During this time period, a [[stirrup]] was added for ease of loading. The Song government attempted to restrict the public use of crossbows and sought ways to keep both body armor and crossbows out of civilian ownership.{{sfn|Needham|1994|p=145}} Despite the ban on certain types of crossbows, the weapon experienced an upsurge in civilian usage as both a hunting weapon and pastime. The "romantic young people from rich families, and others who had nothing particular to do" formed crossbow-shooting clubs as a way to pass time.{{sfn|Needham|1994|p=146}}

Military crossbows were armed by treading, or basically placing the feet on the bow stave and drawing it using one's arms and back muscles. During the Song dynasty, stirrups were added for ease of drawing and to mitigate damage to the bow. Alternatively, the bow could also be drawn by a belt claw attached to the waist, but this was done lying down, as was the case for all large crossbows. Winch-drawing was used for the large mounted crossbows as seen below, but evidence for its use in Chinese hand-crossbows is scant.{{sfn|Needham|1994|p=150}}

Around the third century BC, [[An Dương Vương|King An Dương]] of [[Âu Lạc]] (modern-day [[northern Vietnam]]) and (modern-day [[southern China]]) commissioned a man named [[Cao Lỗ]] (or Cao Thông) to construct a crossbow and christened it "Saintly Crossbow of the Supernaturally Luminous Golden Claw" ''(nỏ thần)'', which could kill 300 men in one shot.{{sfn|Kelley|2014|p=88}}{{sfn|Taylor|1983|p=21}} According to historian Keith Taylor, the crossbow, along with the word for it, seems to have been introduced into China from [[Austroasiatic]] peoples in the south around the fourth century BC.{{sfn|Taylor|1983|p=21}} However, this is contradicted by crossbow locks found in ancient Chinese [[Zhou dynasty]] tombs dating to the 600s BC.{{sfn|Loades|2018}}

In 315 AD, Nu Wen taught the [[Chams]] how to build fortifications and use crossbows. The Chams would later give the Chinese crossbows as presents on at least one occasion.{{sfn|Needham|1994|p=145}}

=== Ancient Greece ===
[[File:Gastraphetes Rekonstruktion Saalburg.jpg|thumb|upright|Greek ''[[gastraphetes]]'']]

The earliest crossbow-like weapons in Europe probably emerged around the late 5th century BC when the ''[[gastraphetes]]'', an ancient Greek crossbow, appeared. The name means "belly-bow";{{sfn|DeVries|2003|p=127}} the concave withdrawal rest at one end of the stock was placed against the belly of the operator, and he could press it to withdraw the slider before attaching a string to the trigger and loading the bolt; this could store more energy than [[Bow (weapon)|Greek bows]].{{sfn|DeVries|2003|p=128}} The device was described by the Greek author [[Hero of Alexandria|Heron of Alexandria]] in his ''Belopoeica'' ("On Catapult-making"), which draws on an earlier account of his compatriot engineer [[Ctesibius]] ([[floruit|fl.]] 285–222 BC). According to Heron, the ''gastraphetes'' was the forerunner of the later [[catapult]], which places its invention some unknown time prior to 399 BC.{{sfn|Campbell|2003|pp=3ff.}} The ''gastraphetes'' was a crossbow mounted on a stock divided into a lower and upper section. The lower was a case fixed to the bow, and the upper was a slider which had the same dimensions as the case.{{sfn|DeVries|2003|p=127}} It was used in the [[Sicilian Wars#The Second Sicilian War (410 BCE–340 BCE)|Siege of Motya]] in 397 BC. This was a key [[Ancient Carthage|Carthaginian]] stronghold in [[Sicily]], as described in the 1st century AD by [[Heron of Alexandria]] in his book ''Belopoeica''.<ref>Stanley M.

=== Ancient Rome ===
[[File:Roman crossbow.jpg|thumb|upright|A crossbow based on depictions from a Roman grave in Gaul.]]

The late 4th century author [[Vegetius]], in his ''De Re Militari'', describes ''arcubalistarii'' (crossbowmen) working together with archers and artillerymen.{{sfn|Loades|2018}} However it is disputed whether arcuballistas were crossbows or torsion-powered weapons. The idea that the arcuballista was a crossbow is due to Vegetius referring separately to it and the ''[[manuballista]]'', which was torsion powered. Therefore, if the arcuballista was not like the manuballista, it may have been a crossbow. According to Vegetius these were well-known devices and hence he did not describe them in depth. Joseph Needham argues against the existence of Roman crossbowmen:{{sfn|Needham|1994|p=172}}

{{blockquote|On the textual side, there is almost nothing but passing references in the military historian Vegetius (fl. + 386) to 'manuballistae' and 'arcuballistae' which he said he must decline to describe as they were so well known. His decision was highly regrettable, as no other author of the time makes any mention of them at all. Perhaps the best supposition is that the crossbow was primarily known in late European antiquity as a hunting weapon, and received only local use in certain units of the armies of Theodosius I, with which Vegetius happened to be acquainted.{{sfn|Needham|1994|p=172}}|Joseph Needham}}

On the other hand [[Arrian]]'s earlier ''Ars Tactica'', from about 136 AD, also mentions 'missiles shot not from a bow but from a machine' and that this machine was used on horseback while in full gallop. It is presumed that this was a crossbow.{{sfn|Loades|2018}}

The only pictorial evidence of Roman arcuballistas comes from sculptural reliefs in [[Roman Gaul]] depicting them in hunting scenes. These are aesthetically similar to both the Greek and Chinese crossbow but it is not clear what kind of release mechanism they used. Archaeological evidence suggests they were similar to the rolling nut mechanism of medieval Europe.{{sfn|Loades|2018}}

=== Medieval Europe ===
[[File:Basilique Saint-Sernin Toulouse 15 (cropped).JPG|thumb|Capital sculpture in the [[Basilica of Saint-Sernin, Toulouse|Basilica of Saint-Sernin]] depicting two primitive crossbows without stirrups, early 12th century]]

There are essentially no references to the crossbow in Europe from the 5th until the 10th century. There is however a depiction of a crossbow as a hunting weapon on four [[Pictish stones]] from [[Scotland in the Early Middle Ages|early medieval Scotland]] (6th to 9th centuries): [[St Vigeans|St. Vigeans no. 1]], [[Glenferness]], [[Shandwick]], and [[Meigle]].<ref>John M. Gilbert, ''Hunting and Hunting Reserves in Medieval Scotland'' (Edinburgh: John Donald, 1979), p. 62.</ref>

The crossbow reappeared again in 947 as a French weapon during the siege of [[Senlis]] and again in 984 at the siege of [[Verdun]].{{sfn|Needham|1994|p=170}} Crossbows were used at the [[battle of Hastings]] in 1066, and by the 12th century they had become common battlefield weapons.<ref name="Sir Ralph Payne-Gallwey 1995 p. 48">Sir Ralph Payne-Gallwey (1995).

The crossbow superseded hand bows in many European armies during the 12th century, except in England, where the [[longbow]] was more popular. Later crossbows (sometimes referred to as [[arbalest]]s), utilizing all-steel prods, were able to achieve power close (and sometime superior) to longbows but were more expensive to produce and slower to reload because they required the aid of mechanical devices such as the cranequin or [[windlass]] to draw back their extremely heavy bows. Usually these could shoot only two bolts per minute versus twelve or more with a skilled archer, often necessitating the use of a [[pavise]] (shield) to protect the operator from enemy fire.<ref name="Robert Hardy 1992 p. 75">Robert Hardy (1992).

[[File:DaVinci Crossbow.JPG|thumb|Sketch by [[Leonardo da Vinci]], c. 1500]]

Crossbows were eventually replaced in warfare by [[gunpowder]] weapons. Early [[hand cannons]] had slower rates of fire and much worse accuracy than contemporary crossbows, but the [[arquebus]] (which proliferated in the mid to late 15th century) matched crossbows' rate of fire while being far more powerful. The [[Battle of Cerignola]] in 1503 was won by Spain largely through the use of matchlock arquebuses, marking the first time a major battle had been won through the use of hand-held firearms. Later, similar competing tactics would feature [[arquebus|harquebusiers]] or [[musket]]eers in formation with pikemen, pitted against cavalry firing [[pistol]]s or [[carbine]]s. While the military crossbow had largely been supplanted by firearms on the battlefield by 1525, the sporting crossbow in various forms remained a popular hunting weapon in Europe until the eighteenth century.<ref>Sir Ralph Payne-Gallwey (1995). ''The Book of the Crossbow''.

=== Islamic world ===

There are no references to crossbows in [[Islamic]] texts earlier than the 14th century. [[Arabs]] in general were averse to the crossbow and considered it a foreign weapon. They called it ''qaus al-rijl'' (foot-drawn bow), ''qaus al-zanbūrak'' (bolt bow) and ''qaus al-faranjīyah'' (Frankish bow). Although [[Muslims]] did have crossbows, there seems to be a split between eastern and western types. Muslims in Spain used the typical European trigger, while eastern Muslim crossbows had a more complex trigger mechanism.{{sfn|Needham|1994|p=175}}

[[Mamluk]] cavalry used crossbows.{{sfn|Loades|2018}}

One reason for this is the crossbow's ability to stop persons carrying explosives without risk of causing detonation.<ref>{{citation | archive-url = https://web.archive.org/web/20140202110148/http://english.pladaily.com.cn/site2/militarydatabase/2006-02/05/content_403376.htm | archive-date=2 February 2014| url = http://english.pladaily.com.cn/site2/militarydatabase/2006-02/05/content_403376.htm | title = New crossbow shoots with great accuracy}}</ref> During the [[July 2009 Ürümqi riots|Xinjiang riots of July 2009]], Crossbows were used by security forces to suppress rioters.<ref>Bingham, John.

== Comparison to conventional bows ==

With a crossbow, archers could release a draw force far in excess of what they could have handled with a bow. 

Furthermore, the crossbow could hold the tension indefinitely, whereas even the strongest longbowman could only hold a drawn bow for a short time. The ease of use of a crossbow allows it to be used effectively with little training, while other types of bows take far more skill to shoot accurately.<ref>{{Cite news|url=http://www.wideopenspaces.com/pros-cons-crossbow-hunting/|title=These Are The Pros and Cons of Crossbow Hunting|date=1 September 2016|work=Wide Open Spaces|access-date=11 January 2018|language=en-US}}</ref> 

The disadvantage is the greater weight and clumsiness to reload compared to a bow, as well as the slower rate of shooting and the lower efficiency of the acceleration system, but there would be reduced [[Hysteresis#Elastic hysteresis|elastic hysteresis]], making the crossbow a more accurate weapon.

Medieval European crossbows had a much smaller draw length than bows, so that for the same energy to be imparted to the projectile the crossbow had to have a much higher draw weight.

A direct comparison between a fast hand-drawn replica crossbow and a longbow shows a 6:10 rate of shooting<ref>[https://www.youtube.com/watch?v=HagCuGXJgUs&feature=grec_index Video comparing longbow and crossbow], [[YouTube]]. Retrieved 16 September 2010</ref> or a 4:9 rate within 30 seconds and comparable weapons.<ref>[https://www.youtube.com/watch?v=7g-0-RK3cjk longbow vs crossbow behind a pavese], [[YouTube]].

== Legislation ==
{{Main|Laws on crossbows}}
[[file:Armbrustschiessen.jpg|thumb|Modern competition crossbow]]

Today, the crossbow often has a complicated legal status due to the possibility of lethal use and its similarities to both firearms and bows.

While some jurisdictions treat crossbows in the same way as firearms, many others do not require any sort of license to own a crossbow. 

The legality of using a crossbow for hunting varies widely in different jurisdictions.
