The '''1900s''' (pronounced "nineteen-hundreds") was a [[decade]] that began on January 1, 1900, and ended on December 31, 1909. The [[Edwardian era]] (1901–1910) covers a similar span of time. The term "nineteen-hundreds" is sometimes also used to mean the entire century from January 1, 1900, to December 31, 1999 (the years beginning with "19").

<!-- Geopolitics and colonalism -->
The [[Scramble for Africa]] continued, with the [[Orange Free State]], [[South African Republic]], [[Ashanti Empire]], [[Aro Confederacy]], [[Sokoto Caliphate]] and [[Kano Emirate]] being conquered by the [[British Empire]], alongside the [[Battle of Kousséri|French Empire conquering Borno]], the [[Adamawa Wars|German Empire conquering the Adamawa Emirate]], and the [[Battle of Mufilo|Portuguese Empire conquering the Ovambo]]. [[Atrocities in the Congo Free State]] were committed by private companies and the ''[[Force Publique]]'', with a resultant population decline{{Refn|"I suggest that it is impossible to separate deaths caused by massacre and starvation from those due to the pandemic of sleeping sickness (trypanosomiasis) which decimated central Africa at the time." - [[Neal Ascherson]] (1999)<ref>{{cite book|last=Ascherson|first=Neal|author-link=Neal Ascherson|title=The King Incorporated: Leopold the Second and the Congo|year=1999|publisher=Granta|location=London|isbn=1-86207-290-6|edition=New|page=9}}</ref>|name=congodecline|group=note}} of 1 to 15 million. From 1904 to 1908, German colonial forces in [[German South West Africa|South West Africa]] led a [[Herero and Nama genocide|campaign of ethnic extermination and collective punishment]], genociding 24,000 to 100,000 [[Herero people|Hereros]] and 10,000 [[Nama people|Nama]]. The [[First Moroccan Crisis|First Moroccan]] and [[Bosnian Crisis|Bosnian crises]] led to worsened tensions in Europe that would ultimately lead to the [[World War I]] in the next decade. [[Cuba]], [[Bulgaria]], and [[Norway]] became independent.

<!-- Warfare and natural disasters -->
The deadliest conventional war of this decade was the [[Russo-Japanese War]], fought over rival [[Imperialism|imperial]] ambitions in [[Manchuria]] and the [[Korean Empire]]. Russia suffered a humiliating defeat in this conflict, contributing to a growing domestic unrest which culminated in the [[Russian Revolution of 1905]]. Unconventional wars of similar scale include insurrections in the [[Philippine–American War|Philippines (1899–1913)]], [[Boxer Rebellion|China (1899–1901)]], and [[Thousand Days' War|Colombia (1899–1902)]]. Lesser conflicts include interstate wars such as the [[Second Boer War]] (1899–1902), the [[Kuwaiti–Rashidi war]] (1900–1901), and the [[First Saudi–Rashidi War (1903–1907)|Saudi–Rashidi War]] (1903–1907), as well as failed uprisings and revolutions in [[Bailundo revolt|Portuguese Angola (1902–1904)]], [[Ilinden–Preobrazhenie Uprising|Rumelia (1903)]], [[1904 Sasun uprising|Ottoman Eastern Anatolia (1904)]], [[Revolution of 1904|Uruguay (1904)]], [[1904–1905 uprising in Madagascar|French Madagascar (1905–1906)]], [[Argentine Revolution of 1905|Argentina (1905)]], [[Persian Constitutional Revolution|Persia (1905–1911)]], [[Maji Maji Rebellion|German East Africa (1905–1907)]], and [[1907 Romanian peasants' revolt|Romania (1907)]]. [[Chinese famine of 1906–1907|A major famine took place in China from 1906 to 1907]], possibly leading to 20–25 million deaths. This famine was directly caused by the 1906 China floods (April–October 1906), which hit the Huai River particularly hard and destroyed both the summer and autumn harvest. The [[1908 Messina earthquake]] caused 75,000–82,000 deaths.

<!-- Social movements -->
[[First-wave feminism]] made advances, with universities being opened for women in Japan, Bulgaria, Cuba, Russia, and Peru. In 1906, Finland granted women the right to vote,<ref name="finlande1">{{cite web |title=Finnish women won the right to vote a hundred years ago – Embassy of Finland, The Hague : Current Affairs |url=http://www.finlande.nl/public/default.aspx?contentid=112162&nodeid=35916&contentlan=2&culture=en-US |url-status=deviated |archive-url=https://web.archive.org/web/20140423070026/http://www.finlande.nl/public/default.aspx?contentid=112162&nodeid=35916&contentlan=2&culture=en-US |archive-date=2014-04-23 |access-date=2012-10-31 |publisher=Finlande.nl}}</ref> the first European country to do so.<ref name="autogenerated6">{{cite web |title=BBC Radio 4 – Woman's Hour – Women's History Timeline: 1900 – 1909 |url=https://www.bbc.co.uk/radio4/womanshour/timeline/1900.shtml |access-date=2012-11-07 |publisher=Bbc.co.uk}}</ref> The foundation of the [[Women's Social and Political Union]] by [[Emmeline Pankhurst]] in 1903 led to the rise of the [[Suffragette|Suffragettes]] in Great Britain and Ireland. In 1908, [[Young Turk Revolution|a revolution took place]] in the Ottoman Empire, where the [[Young Turks]] movement restored the [[Ottoman constitution of 1876]], establishing the [[Second Constitutional Era]]. Subsequently, ethnic tensions rose, and in 1909, [[Adana massacre|up to 30,000 mainly Armenian civilians in Adana were massacred]] by Muslim civilians.

<!-- Technology and culture -->
The decade saw the widespread application of the [[History of the internal combustion engine|internal combustion engine]] including mass production of the automobile, as well as the introduction of the [[typewriter]]. The ''[[Wright Flyer]]'' performed the first recorded controlled, powered, sustained heavier than air flight on December 17, 1903. [[Reginald Fessenden]] of [[East Bolton, Quebec]], Canada made what appeared to be{{clarify|date=October 2021}} the first audio radio broadcasts of entertainment and music ever made to a general audience. The first huge success of American cinema, as well as the largest experimental achievement to this point, was the 1903 film ''[[The Great Train Robbery (1903 film)|The Great Train Robbery]]'', directed by [[Edwin S. Porter]], while the world's first feature film, ''[[The Story of the Kelly Gang]]'', was released on December 26, 1906, in [[Melbourne]], Australia. Popular books of this decade included ''[[The Tale of Peter Rabbit]]'' (1902) and ''[[Anne of Green Gables]]'' (1908), which sold 45 million and 50 million copies respectively. <!-- It seems that frequency of featuring in hymnals is the only available measure of popularity. If better methods can be found, propose something on the talk page. -->Popular songs of this decade include "[[Lift Every Voice and Sing]]" and "[[What Are They Doing in Heaven?]]", which have been featured in 42 and 16 [[hymnal]]s respectively.

During the decade, the world population increased from 1.60 to 1.75 billion, with approximately 580 million births and 450 million deaths in total. As of June 2025, the only remaining living person born in this decade is [[Ethel Caterham]], born 21 August 1909. The last living man from this decade was [[Juan Vicente Pérez]] (27 May 1909 – 2 April 2024).

==Pronunciation varieties==
There are several main varieties of how individual years of the decade are pronounced. Using 1906 as an example, they are "nineteen-oh-six", "nineteen-six", and "nineteen-aught-six". Which variety is most prominent depends somewhat on global region and generation. "Nineteen-oh-six" is the most common; "nineteen-six" is less common. In [[American English]], "nineteen-aught-six" is also recognized but not much used.{{citation needed|date=April 2022}}

==Economics==

* The [[gold standard]] was the dominant international monetary system in the 1900s, with all major industrial powers operating under its rules and exchange rates between major currencies remaining fixed.<ref name=":0">{{cite book|title=II Lessons from the Gold Standard and Bretton Woods|url=https://www.elibrary.imf.org/view/book/9781557750280/ch009.xml|work=IMF eLibrary|publisher=International Monetary Fund |isbn=978-1-55775-028-0 |access-date=13 March 2025}}</ref>
* [[Colony|Colonial]] economic relationships significantly shaped global economic patterns, with European powers establishing colonies in Africa, Asia, and the Americas, extracting resources such as cotton, rubber, ivory, gold, and diamonds, and imposing trade policies designed to benefit the colonizers at the expense of the colonized populations.<ref>{{cite web |title=Global Economic Development from 1750 to 1900 |url=https://library.fiveable.me/ap-world/unit-6/global-economic-development-1750-1900/study-guide/2Qcdz5fpK21eAQhq7cY6 |access-date=13 March 2025 |work=Fiveable}}</ref>
* The [[Panic of 1901]] was the first [[New York Stock Exchange]] [[stock market crash]].

* [[Germany]]'s industrial growth was quick during this period. From 1895 to 1907, the number of workers in machine building doubled from slightly more than half a million to well over a million. German steel production, which had exceeded Britain's in 1893, continued to grow, and by the end of the decade Germany dominated all major Continental markets except France.<ref>{{cite encyclopedia|title=Germany - The economy, 1890-1914|url=https://www.britannica.com/place/Germany/The-economy-1890-1914|encyclopedia=Britannica|access-date=13 March 2025}}</ref>
* [[Russia]] experienced rapid economic growth from 1900 to 1905, with the economy expanding at 4 percent annually. However, in 1905, the Russian economy went into a severe slump following an unprecedented wave of worker strikes, peasant protests, and military defeat in the [[Russo-Japanese War]].<ref>{{cite web|title=Russia's Home Front, 1914-1922: The Economy|url=https://warwick.ac.uk/fac/soc/economics/staff/mharrison/public/rgwr_postprint.pdf|work=University of Warwick|access-date=13 March 2025}}</ref>
* The [[United Kingdom]]'s economic dominance was increasingly challenged during this decade. While Britain remained the world's largest capital exporter and shipping power, both the United States and Germany surpassed Britain in industrial production, particularly in steel manufacturing.<ref name=":0" />
* The [[Panic of 1907]], also known as the 1907 Bankers' Panic, was a significant financial crisis that occurred in the United States when the stock market fell close to 50% from its peak the previous year. The crisis spread to other countries and was eventually resolved through interventions led by J.P. Morgan.<ref>{{cite book|title=II Lessons from the Gold Standard and Bretton Woods|url=https://www.elibrary.imf.org/view/book/9781557750280/ch009.xml|work=IMF eLibrary|publisher=International Monetary Fund |isbn=978-1-55775-028-0 |access-date=13 March 2025}}</ref>
* [[France]] was a major capital exporter during this period, lending substantial portions of GDP to developing economies. The country implemented significant labor reforms, including the introduction of a mandatory weekly rest day in 1906 and the creation of the [[Ministry of Labour (France)|Ministry of Labour]] the same year.<ref>{{Cite book |last=Béthouart |first=Bruno |url=https://books.google.com/books?id=hMUTAQAAIAAJ |title=Le Ministère du travail et de la sécurité sociale de la Libération au début de la Ve République |date=2006 |publisher=Presses universitaires de Rennes |isbn=978-2-7535-0327-4 |language=fr}}</ref>
* In [[Japan]], the victory in the [[Russo-Japanese War]] (1904-1905) accelerated industrial development. Under the leadership of Prime Minister [[Katsura Tarō]], Japan expanded its heavy industry, particularly in shipbuilding and armaments, and strengthened its position as an emerging economic power in Asia. However this growth was coupled with a surge in labour disputes.<ref>{{Cite web |date=2011-10-01 |title=Kazuo Nimura 'The Formation of Japanese Labor Movement;1868-1914' |url=http://oohara.mt.tama.hosei.ac.jp/nk/English/eg-formation.html |access-date=2025-03-13 |archive-date=October 1, 2011 |archive-url=https://web.archive.org/web/20111001233543/http://oohara.mt.tama.hosei.ac.jp/nk/English/eg-formation.html |url-status=dead }}</ref>
* Germany's urbanization accelerated rapidly, with only 40 percent of Germans living in rural areas by 1910, compared to 67 percent at the birth of the empire. Cities of more than 100,000 inhabitants accounted for one-fifth of the population by the end of the decade.<ref>{{cite encyclopedia|title=Germany - The economy, 1890-1914|url=https://www.britannica.com/place/Germany/The-economy-1890-1914|encyclopedia=Britannica|access-date=13 March 2025}}</ref>
* [[Italy]]'s economy during this decade was characterized by the growing industrialization in the north, while the southern regions remained predominantly agricultural. Prime Minister [[Giovanni Giolitti]]'s economic policies encouraged industrial growth, particularly in the automotive and textile sectors.<ref>{{Cite web |date=2025-03-12 |title=Italy - Giolitti, Unification, Politics {{!}} Britannica |url=https://www.britannica.com/place/Italy/The-Giolitti-era-1900-14 |access-date=2025-03-13 |website=www.britannica.com |language=en}}</ref>
* Russia's economy began growing again from 1909 following the political and economic crisis of 1905-1907. This recovery continued until the outbreak of World War I, though Russia remained the poorest of the great powers.<ref>{{cite web|title=Russia's Home Front, 1914-1922: The Economy|url=https://warwick.ac.uk/fac/soc/economics/staff/mharrison/public/rgwr_postprint.pdf|work=University of Warwick|access-date=13 March 2025}}</ref>

* Wide popularity of home [[phonograph]]. "The market for home machines was created through technological innovation and pricing: Phonographs, gramophones, and graphophones were cleverly adapted to run by spring-motors (you wound them up), rather than by messy batteries or treadle mechanisms, while the musical records were adapted to reproduce loudly through a horn attachment. The cheap home machines sold as the $10 Eagle graphophone and the $40 (later $30) Home phonograph in 1896, the $20 Zon-o-phone in 1898, the $3 Victor Toy in 1900, and so on. Records sold because their fidelity improved, mass production processes were soon developed, advertising worked, and prices dropped from one and two dollars to around 35 cents.".<ref>"The most thorough account of the history of the phonograph is still Oliver Read and Walter L. Welch, Tin Foil to Stereo: Evolution of the Phonograph, 2nd ed. (Indianapolis, IN: Howard W. Sams & Co., 1976). For a recent version of the story see Leonard DeGraaf, "Thomas Edison and the Origins of the Entertainment Phonograph" NARAS Journal 8 (Winter/Spring 1997/8) 43–69, as well as William Howland Kenney's recent and welcome Recorded Music in American Life: The Phonograph and Popular Memory, 1890–1945 (New York: Oxford University Press, 1999). Much of the technocentric focus of literature on the phonograph (a focus Kenney's cultural history finally shifts) may derive from the interests of collectors, for whom I have the utmost respect. In the interest of simplicity, I am going to use the eventual American generic, "phonograph," for the graphophone and gramophone as well as the phonograph. Of course in Britain and much of the postcolonial world, the generic is "gramophone.""</ref><ref>{{cite web|url=http://web.mit.edu/comm-forum/papers/gitelman.html#fn2|title=How Users Define New Media: A History of the Amusement Phonograph|work=mit.edu|access-date=January 5, 2010|archive-date=October 9, 2016|archive-url=https://web.archive.org/web/20161009182818/http://web.mit.edu/comm-forum/papers/gitelman.html#fn2|url-status=dead}}</ref> In 1907, a [[Victor Talking Machine Company|Victor Records]] recording of [[Enrico Caruso]] singing [[Ruggero Leoncavallo]]'s "[[Vesti la giubba]]" becomes the first to sell a million copies.<ref>Linehan, Andrew.

* 1901 – The first radio [[Receiver (radio)|receiver]] (successfully received a radio transmission). This receiver was developed by [[Guglielmo Marconi]]. Marconi established a wireless transmitting station at Marconi House, [[Rosslare Strand]], [[County Wexford]], Ireland in 1901 to act as a link between [[Poldhu]] in [[Cornwall]] and [[Clifden]] in [[County Galway]]. He soon made the announcement that on December 12, 1901, using a {{convert|sp=us|500|ft||adj=on}} kite-supported antenna for reception, the message was received at [[Signal Hill (Newfoundland and Labrador)|Signal Hill]] in [[St. John's, Newfoundland and Labrador|St John]]'s, [[Newfoundland and Labrador|Newfoundland]] (now part of Canada), signals transmitted by the company's new high-power station at Poldhu, Cornwall. The distance between the two points was about {{convert|sp=us|2200|mi|}}. {{Br}}Heralded as a great scientific advance, there was—and continues to be—some skepticism about this claim, partly because the signals had been heard faintly and sporadically. There was no independent confirmation of the reported reception, and the transmissions, consisting of the [[Morse code]] letter ''S'' sent repeatedly, were difficult to distinguish from [[atmospheric noise]]. (A detailed technical review of Marconi's early transatlantic work appears in John S. Belrose's work of 1995.)<ref>{{cite web|url=http://www.ieee.ca/millennium/radio/radio_differences.html |title=Fessenden and Marconi: Their Differing Technologies and Transatlantic Experiments During the First Decade of this Century |publisher=Ieee.ca |access-date=2009-01-29| archive-url= https://web.archive.org/web/20090123214652/http://www.ieee.ca/millennium/radio/radio_differences.html| archive-date= 23 January 2009 | url-status= live}}</ref> The Poldhu transmitter was a two-stage circuit.<ref>"''[https://ieeexplore.ieee.org/stamp/stamp.jsp?arnumber=1305565 Marconi and the History of Radio]''".</ref><ref>John S.

* 1902 – [[Willis Carrier]] of [[Angola, New York]], invented the first indoor [[air conditioning]]. "He designed his spray driven air conditioning system which controlled both temperature and humidity using a [[nozzle]] originally designed to spray [[insecticide]]. He built his "Apparatus for Treating Air" (U.S. Pat. #808897) which was patented in 1906 and using chilled coils which not only controlled heat but could lower the humidity to as low as 55%. The device was even able to adjust the humidity level to the desired setting creating what would become the framework for the modern air conditioner. By adjusting the air movement and temperature level to the refrigeration coils he was able to determine the size and capacity of the unit to match the need of his customers. While Carrier was not the first to design a system like this his was much more stable, successful and safer than other versions and took air conditioning out of the Dark Ages and into the realm of science."<ref>{{cite web|url=http://www.air-conditioners-and-heaters.com/willis_carrier.htm|title=Willis Carrier air conditioning|work=air-conditioners-and-heaters.com}}</ref>
* 1902/1906/1908 – [[Sir James Mackenzie]] of [[Scone, Scotland]], invented an early [[Lie detection|lie detector]] or [[polygraph]]. MacKenzie's polygraph "could be used to monitor the [[Circulatory system|cardiovascular]] responses of his patients by taking their [[pulse]] and [[blood pressure]].<ref>{{Cite web|url=http://www.umw.edu/hisa/resources/Student%20Projects/Singel/students.umw.edu/_ksing2os/polygraph/origin.html|archiveurl=https://web.archive.org/web/20100204031232/http://www.umw.edu/hisa/resources/Student%20Projects/Singel/students.umw.edu/_ksing2os/polygraph/origin.html|url-status=dead|title=Kati Singel, "The Polygraph:The Modern Lie Detector"|archivedate=February 4, 2010}}</ref> He had developed an early version of his device in the 1890s, but had Sebastian Shaw, a [[Lancashire]] watchmaker, improve it further.

* 1902 – The [[Wright brothers]] of [[Ohio]], United States create the 1902 version of the [[Wright Glider]]. It was the third free-flight glider built by them and tested at [[Kitty Hawk, North Carolina]]. This was the first of the brothers' gliders to incorporate [[flight dynamics|yaw control]], and its design led directly to the [[Wright Flyer|1903 ''Wright Flyer'']]. The brothers designed the 1902 glider during the winter of 1901–1902 at their home in [[Dayton, Ohio]]. They designed the wing based on data from extensive airfoil tests conducted on a homemade [[wind tunnel]]. They built many of the components of the glider in Dayton, but they completed assembly at their Kitty Hawk camp in September 1902. They began testing on September 19. Over the next five weeks, they made between 700 and 1000 glide flights (as estimated by the brothers, who did not keep detailed records of these tests). The longest of these was {{convert|622.5|ft|m|abbr=on}} in 26 seconds.

* 1906 – Sound [[radio broadcasting]] was invented by [[Reginald Fessenden]] and [[Lee De Forest]]. Fessenden and [[Ernst Alexanderson]] developed a high-frequency [[alternator]]-transmitters, an improvement on an already existing device. The improved model operated at a transmitting frequency of approximately 50&nbsp;kHz, although with far less power than Fessenden's rotary-spark transmitters. The alternator-transmitter achieved the goal of transmitting quality audio signals, but the lack of any way to amplify the signals meant they were somewhat weak. On December 21, 1906, Fessenden made an extensive demonstration of the new alternator-transmitter at Brant Rock, showing its utility for point-to-point wireless telephony, including interconnecting his stations to the wire telephone network. A detailed review of this demonstration appeared in ''The American Telephone Journal''.<ref>{{cite web| url = https://earlyradiohistory.us/1907fes.htm| title = Experiments and Results in Wireless Telephony ''The American Telephone Journal''}}</ref> Meanwhile, De Forest had developed the [[Audion tube]] an electronic [[amplifier]] device.

* 1906 – [[Reginald Fessenden]] of [[East Bolton, Quebec]], Canada made what appear to be the first audio radio broadcasts of entertainment and music ever made to a general audience. (Beginning in 1904, the [[United States Navy]] had broadcast daily time signals and weather reports, but these employed [[spark-gap transmitter]]s, transmitting in [[Morse code]]). On the evening of December 24, 1906 ([[Christmas Eve]]), Fessenden used the alternator-transmitter to send out a short program from [[Ocean Bluff-Brant Rock, Massachusetts|Brant Rock]], [[Plymouth County, Massachusetts|Plymouth County]], [[Massachusetts]]. It included a phonograph record of [[Ombra mai fù]] (Largo) by [[George Frideric Handel]], followed by Fessenden himself playing the song ''[[O Holy Night]]'' on the [[violin]]. Finishing with reading a passage from the [[Bible]]: 'Glory to God in the highest and on earth peace to men of good will' ([[Gospel of Luke]] 2:14). On December 31, [[New Year's Eve]], a second short program was broadcast. The main audience for both these transmissions was an unknown number of shipboard radio operators along the [[East Coast of the United States]]. Fessenden claimed that the Christmas Eve broadcast had been heard "as far down" as [[Norfolk, Virginia]], while the New Year Eve's broadcast had reached places in the Caribbean. Although now seen as a landmark, these two broadcasts were barely noticed at the time and soon forgotten— the only first-hand account appears to be a letter Fessenden wrote on January 29, 1932, to his former associate, Samuel M. Kinter.<ref>{{Cite book|url=https://babel.hathitrust.org/cgi/pt?id=uc1.b4540711;view=1up;seq=167|title=Fessenden, Builder of Tomorrows|last=Fessenden|first=Helen May Trott|publisher=Coward-McCann|year=1940|isbn=978-0405060472|location=New York|pages=153–154}}</ref><ref name="ContinuumRadio">{{cite book|title=The Continuum Encyclopedia of Popular Music of the World|chapter=Radio|pages= 451–461|first=Stephen|last=Barnard|author2=Donna Halper and Dave Laing}}</ref>

* 1907 – The [[Photostat machine]] begins the modern era of document imaging. The Photostat machine was invented in [[Kansas City, Kansas|Kansas City]], [[Kansas]], United States by Oscar Gregory in 1907, and the Photostat Corporation was incorporated in [[Rhode Island]] in 1911. "Rectigraph and Photostat machines (Plates 40–42) combined a large camera and a developing machine and used sensitized paper furnished in 350-foot rolls. "The prints are made direct on sensitized paper, no negative, plate or film intervening. The usual exposure is ten seconds. After the exposure has been made the paper is cut off and carried underneath the exposure chamber to the developing bath, where it remains for 35 seconds, and is then drawn into a fixing bath. While one print is being developed or fixed, another exposure can be made. When the copies are removed from the fixing bath, they are allowed to dry by exposure to the air, or may be run through a drying machine. The first print taken from the original is a 'black' print; the whites in the original are black and the blacks, white. (Plate 43) A white 'positive' print of the original is made by rephotographing the black print. As many positives as required may be made by continuing to photograph the black print." (The American Digest of Business Machines, 1924.) Du Pont Co. files include black prints of graphs dating from 1909, and the company acquired a Photostat machine in 1912.&nbsp;...
