After the conquest of the Pannonian Basin, the Iazyges appear to have ruled over some measure of the remaining Germanic, Celtic, and Dacian populations, with the hilly areas north of modern-day Budapest retaining strong Germanic traditions, with a significant presence of Germanic burial traditions.{{sfn|Higham|2018|p=47}} Items of Celtic manufacturing appear up until the late 2nd century{{NBSP}}AD, in the northern area of the Carpathian Basin.{{sfn|Higham|2018|pp=47–48}}

During the time of [[Augustus]], the Iazyges sent an embassy to Rome to request friendly relations.{{sfn|Stover|2012|p=9}} In a modern context, these "friendly relations" would be similar to a [[non-aggression pact]].{{sfn|Sands|2016|p=13}} Around this time, some of the western parts of the land of the Iazyges were occupied, apparently without conflict, by the [[Quadi]], which scholar Nicholas Higham states "suggests long-term collaboration between [them]".{{sfn|Higham|2018|p=47}}

Later, during the reign of [[Tiberius]], the Iazyges became one of many new client-tribes of Rome. Roman client states were treated according to the Roman tradition of patronage, exchanging rewards for service.{{sfn|Luttwak|1981|p=21}}{{sfn|Salway|1982|p=208}} The client king was called ''socius et amicus Romani Populi'' (ally and friend of the Roman People); the exact obligations and rewards of this relationship, however, are vague.{{sfn|Elton|1996|p=12}} Even after being made into a client state, the Iazyges conducted raids across their border with Rome, for example in 6{{nbsp}}AD and again in 16{{nbsp}}AD. In 20{{nbsp}}AD the Iazyges moved westward along the [[Carpathians]] into the [[Pannonian Steppe]], and settled in the steppes between the Danube and the [[Tisza river]], taking absolute control of the territory from the Dacians.{{sfn|Cunliffe|2015|p=284}} In 50{{nbsp}}AD, an Iazyges cavalry detachment assisted King [[Vannius]], a Roman client-king of the Quadi, in his fight against the [[Suevi]].{{sfn|Malcor|Littleton|2013|p=16}}{{sfn|Bârcă|Cociş|2013|p=104}}

In the [[Year of Four Emperors]], 69{{nbsp}}AD, the Iazyges gave their support to [[Vespasian]], who went on to become the sole emperor of Rome.{{sfn|McLynn|2010|p=314}} The Iazyges also offered to guard the Roman border with the Dacians to free up troops for Vespasian's invasion of Italy; Vespasian refused, however, fearing they would attempt a takeover or defect. Vespasian required the chiefs of the Iazyges to serve in his army so they could not organize an attack on the undefended area around the Danube.{{sfn|McLaughlin|2016|p=147}}{{sfn|Hoyos|2013|p=221}}{{sfn|Henderson|1927|p=158}}{{sfn|Master|2016|p=135}}{{sfn|Saddington|1982|pp=41 & 115}} Vespasian enjoyed support from the majority of the [[Germanic peoples|Germanic]] and Dacian tribes.{{sfn|McLynn|2010|p=314}}

Domitian's campaign against Dacia was mostly unsuccessful; the Romans, however, won a minor skirmish that allowed him to claim it as a victory, even though he paid the King of Dacia, [[Decebalus]], an annual tribute of eight million sesterces in tribute to end the war.{{sfn|McLynn|2010|p=314}}{{sfn|Jones|1993|p=150}} Domitian returned to Rome and received an [[ovation]], but not a full [[Roman triumph|triumph]]. Considering that Domitian had been given the title of [[Imperator]]—for military victories 22 times, this was markedly restrained, suggesting the populace—or at least the senate—was aware it had been a less-than-successful war, despite Domitian's claims otherwise.{{sfn|Grainger|2004|p=22}}{{efn|Some sources say that Domitian was offered a triumph, but refused.{{sfn|Murison|1999|p=254}}}} In 89{{nbsp}}AD, however, Domitian invaded the Iazyges along with the Quadi and Marcomanni. Few details of this war are known but it is recorded that the Romans were defeated,{{sfn|Mattingly|2010|p=94}} it is, however, known that Roman troops acted to repel simultaneous incursion by the Iazyges into Dacian lands.{{sfn|Bârcă|2013|p=18}}

In early 92{{nbsp}}AD the Iazyges, Roxolani, Dacians, and [[Suebi]] invaded the Roman province of Pannonia—modern-day Croatia, northern Serbia, and western Hungary.{{sfn|Grainger|2004|p=22}}{{sfn|Henderson|1927|p=166}}{{sfn|Jones|1908|p=143}} Emperor Domitian called upon the [[Quadi]] and the [[Marcomanni]] to supply troops to the war. Both client-tribes refused to supply troops so Rome declared war upon them as well. In May 92{{nbsp}}AD, the Iazyges annihilated the Roman [[Legio XXI Rapax]] in battle.{{sfn|Grainger|2004|p=22}}{{sfn|Jones|1908|p=143}}{{sfn|Swan|2004|p=165}} Domitian, however, is said to have secured victory in this war by January of the next year.{{sfn|Ryberg|1967|p=30}} It is believed, based upon a rare Aureus coin showing an Iazyx with a Roman standard kneeling, with the caption of "''Signis a Sarmatis Resitvtis''", that the standard is taken from the annihilated Legio XXI Rapax was returned to Rome at the end of the war.{{sfn|Tsetskhladze|2001|p=424}} Although the accounts of the Roman-Iazyges wars of 89 and 92{{nbsp}}AD are both muddled, it has been shown they are separate wars and not a continuation of the same war.{{sfn|Habelt|1967|p=122}} The threat presented by the Iazyges and neighbouring people to the Roman provinces was significant enough that Emperor [[Trajan]] travelled across the Mid and Lower Danube in late 98 to early 99, where he inspected existing fortification and initiated the construction of more forts and roads.{{sfn|Bârcă|2013|p=18}}

[[Tacitus]], a Roman Historian, records in his book ''[[Germania (book)|Germania]]'', which was written in 98{{nbsp}}AD, that the [[Osi (ancient tribe)|Osi]] tribes paid tribute to both the Iazyges and the Quadi, although the exact date this relationship began is unknown.{{sfn|Hastings|Selbie|Gray|1921|p=589}}

During the [[Flavian dynasty]], the princes of the Iazyges were trained in the Roman army, officially as an honor but in reality serving as a hostage, because the kings held absolute power over the Iazyges.{{sfn|Wellesley|2002|p=133}} There were offers from the princes of the Iazyges to supply troops but these were denied because of the fear they might revolt or desert in a war.{{sfn|Ash|Wellesley|2009|p=3–5}}
