Editing Procopius (usurper) (section)

=== Into enemy territory ===
Meanwhile, Procopius was entrusted with fortifying Roman defenses in [[Mesopotamia]]. Tasked with leading a force of around 30,000 men, Procopius and his subordinate, [[Sebastianus (magister peditum)|Sebastianus]], were stationed to defend key positions along the Upper [[Tigris River]], anticipating an advance from [[Military of the Sasanian Empire|Shapur’s forces]].<ref name=":0" /><ref>{{Cite book |last=Matthews |first=John |url=https://books.google.com/books?id=hZqgAAAAMAAJ |title=The Roman Empire of Ammianus |date=1989 |publisher=Johns Hopkins University Press |isbn=978-0-8018-3965-8 |page=167 |language=en}}</ref> Procopius was tasked with coordinating Roman defensive efforts in the east, specifically working with King [[Arsaces II of Armenia]] to secure the strategically vital [[Bitlis District|Bitlis Pass]].<ref name=":2">{{Cite book |last=Lacey |first=Jim |url= |title=Great Strategic Rivalries: From the Classical World to the Cold War |date=2016 |publisher=Oxford University Press |isbn=978-0-19-062046-2 |pages=137–138 |language=en}}</ref> Procopius' efforts were vital in securing the eastern front and preparing for the Persian response to Julian's offensive.<ref name=":0" />

Procopius prepared for the possibility of advancing his troops southward to join with Emperor Julian’s soldiers in Assyria.<ref name=":1" /> This location was crucial for controlling access between the Roman and Persian spheres of influence, and its defense was integral to safeguarding the Roman presence in the region.<ref name=":1">François Paschoud,  ''Zosime.

When Procopius reached the main Roman army near [[Thilsaphata]], between [[Nisibis]] and [[Singara]], he met the new emperor, [[Jovian (emperor)|Jovian]].<ref name=":0" />

Though Julian had died without naming a successor,{{sfn|Potter|2004|p=518}} a rumor spread that he had ordered Procopius to take the purple in case of his death.{{sfn|Curran|1998|p=89}} Fearing Jovian's wrath, which had caused the death of another army candidate to the throne (Jovianus),{{sfn|Jones|Martindale|Morris|pp=460–461}} Procopius went into hiding, but later supervised the transport of Julian's body to [[Tarsus, Mersin|Tarsus]] and its subsequent burial,{{sfn|Hughes|2013|p=18}} and only later went to Caesarea with his family.<ref>According to [[Philostorgius]], since his wife could not bear their escape, Procopius went to Caesarea, but to live in one of Eunomius's properties (''Historia Ecclesiastica'' 9.5).</ref>{{sfn|Jones|Martindale|Morris|pp= 742–743}}

After Jovian's death, the new emperors, [[Valentinian I]] and [[Valens]], sent some soldiers to arrest Procopius.{{sfn|Potter|2004|p=522}} He surrendered, but asked to meet his family; he had his captors dine and drink, and then seized the opportunity to flee with his family, first to the [[Black Sea]] and later to the [[Tauric Chersonese]], where they hid.{{sfn|Hughes|2013|p=40}} However, Procopius lived in constant fear of betrayal or exposure, and decided to go to [[Constantinople]], the Empire's capital, to ask Strategius for help.{{sfn|Jones|Martindale|Morris|pp= 742–743}}

Becoming aware of discontent caused by the policies of Valens's praetorian prefect and father-in-law, Petronius,{{sfn|Hughes|2013|p=40}}{{sfn|Jones|Martindale|Morris|p=691}} Procopius decided to declare himself Emperor. He bribed two legions which were then resting at [[Constantinople]] to support his efforts, and took control of the imperial city. Shortly after this he proclaimed himself Emperor on 28 September  365, and quickly took control of the provinces of [[Thrace]], and later [[Bithynia]].{{Sfn|Curran|1998|p=90}} Procopius promoted himself as an educated philosopher, well versed in the Greek language of the Eastern Empire, and highlighted Valens's weakness in this area, to gain the support of the Hellenized Eastern aristocrats.{{sfn|Lenski|2003|pp=92–96}} He also emphasized his link to the Constantinian dynasty by appearing in public with Constantius II’s widow [[Faustina (wife of Constantius II)|Faustina]] and their daughter [[Constantia (wife of Gratian)|Constantia]], an act which Ammianus considered to have earned him greater support.{{sfn|Hughes|2013|p=42}}

Though Valens initially despaired of subduing the rebellion, and was inclined to come to terms with the usurper, he quickly rallied, guided by the counsels of [[Salutius]] and [[Arintheus]], and the superior ability of his generals prevailed in two battles at [[Battle of Thyatira|Thyatira]] and [[Nacolia]] where Procopius's forces were defeated.<ref>[[Edward Gibbon]],''The Decline And Fall Of The Roman Empire'', (The Modern Library, 1932), chap. XXV., p. 852, 853</ref> He fled the battlefield, and was for a while a fugitive in the wilds of [[Phrygia]], but was soon betrayed to Valens due to the treachery of his two generals Agilonius and [[Gomoarius]], he was captured. Valens had his rival executed on 27 May 366{{sfn|Jones|Martindale|Morris|pp= 742–743}} through beheading.{{Sfn|Curran|1998|p=91}}{{sfn|Potter|2004|p=525}} His head was then sent to Valens's elder brother and co-emperor Valentinian I.{{sfn|Hughes|2013|p=48}}
