Editing Iazyges (section)

===After the Marcomannic Wars===
In 177, the Iazyges, the [[Buri tribe|Buri]], and other Germanic tribes{{efn|The only Germanic tribe that is named is the Buri, but there were more.{{sfn|Mócsy|2014|p=191}}}} invaded Roman territory again.{{sfn|Mócsy|2014|p=191}} It is said that in 178, Marcus Aurelius took the bloody spear from the [[Temple of Bellona, Rome|Temple of Bellona]] and hurled it into the land of the Iazyges.{{sfn|Ulanowski|2016|p=362}} In 179, the Iazyges and the Buri were defeated, and the Iazyges accepted peace with Rome. The peace treaty placed additional restrictions on the Iazyges but also included some concessions. They could not settle on any of the islands of the Danube and could not keep boats on the Danube. They were, however, permitted to visit and trade with the Roxolani throughout the Dacian Province with the knowledge and approval of its governor, and they could trade in the Roman markets at certain times on certain days.{{sfn|Mócsy|2014|p=191}}{{sfn|Găzdac|2010|p=51}} In 179, the Iazyges and the Buri joined Rome in their war against the Quadi and the Marcomanni after they secured assurances that Rome would prosecute the war to the end and not quickly make a peace deal.{{sfn|Regenberg|2006|p=191}}

As part of a treaty made in 183, [[Commodus]] forbade the Quadi and the Marcomanni from waging war against the Iazyges, the Buri, or the [[Vandals]], suggesting that at this time all three tribes were loyal client-tribes of Rome.{{sfn|McLynn|2010|p=423}}{{sfn|Merrills|Miles|2010|p=28}} In 214, however, [[Caracalla]] led an invasion into the Iazyges' territory.{{sfn|Sydenham|Sutherland|Carson|1936|p=84}} In 236, the Iazyges invaded Rome but were defeated by Emperor [[Maximinus Thrax]], who took the title Sarmaticus Maximus following his victory.{{sfn|Giurescu|Matei|1974|p=32}} The Iazyges, Marcomanni, and Quadi raided Pannonia together in 248,{{sfn|Goldsworthy|2009|p=111}}{{Sfn|Marks|Beatty|1976|p=37}} and again in 254.{{sfn|Drăgan|1985|p=73}} It is suggested the reason for the large increase in the amount of Iazyx raids against Rome was that the Goths led successful raids, which emboldened the Iazyges and other tribes.{{sfn|Matyszak|2014|p=141}} In 260, the Goths took the cities of [[Tyras]] and [[Olbia (Pontic)|Olbia]], again cutting off the Iazyges' trade with the Pontic Steppe and the Black Sea.{{Sfn|Harmatta|1970|pp=47–48}} From 282 to 283, Emperor [[Carus]] lead a successful campaign against the Iazyges.{{sfn|Drăgan|1985|p=73}}{{sfn|Tsetskhladze|2001|p=429}}

The Iazyges and [[Carpi (people)|Carpi]] raided Roman territory in 293, and [[Diocletian]] responded by declaring war.{{sfn|Neusner|1990|p=231}} From 294 to 295, Diocletian waged war upon them and won.{{sfn|Syme|1971|p=226}}{{sfn|Boak|1921|p=319}} As a result of the war, some of the Carpi were transported into Roman territory so they could be controlled.{{sfn|Duruy|1887|p=373}} From 296 to 298, [[Galerius]] successfully campaigned against the Iazyges.{{sfn|Tsetskhladze|2001|p=429}}{{sfn|Kuiper|2011|p=174}} In 358, the Iazyges were at war with Rome.{{sfn|Hornblower|2012|p=723}} In 375, Emperor [[Valentinian I|Valentinian]] had a stroke in [[Brigetio]] while meeting with envoys from the Iazyges.{{efn|Some sources say that the meeting was with the Quadi and not the Iazyges.{{sfn|Bury|2013|p=65}}}}{{sfn|Venning|Harris|2006|p=26}} Around the time of the Gothic migration, which led the Iazyges to be surrounded on their northern and eastern borders by Gothic tribes, and most intensely during the reign of [[Constantine the Great|Constantine I]], a series of earthworks known as the [[Devil's Dykes]] (Ördögárok) was built around the Iazygian territory,{{sfn|Williams|1997|p=256}}{{sfn|Higham|2018|p=66}} possibly with a degree of Roman involvement. Higham suggests that the Iazyges became more heavily tied to the Romans during this period, with strong cultural influence.{{sfn|Higham|2018|p=66}}
