Iazyges in the context of "Sedentary lifestyle"

The barbarian invasions of the third century (212–305) constituted an uninterrupted period of raids within the borders of the Roman Empire, conducted for purposes of plunder and booty by armed peoples belonging to populations gravitating along the northern frontiers: Picts, Caledonians, and Saxons in Britain; the Germanic tribes of Frisii, Saxons, Franks, Alemanni, Burgundians, Marcomanni, Quadi, Lugii, Vandals, Juthungi, Gepids and Goths (Tervingi in the west and Greuthungi in the east), the Dacian tribes of the Carpi and the Sarmatian tribes of Iazyges, Roxolani and Alans, as well as Bastarnae, Scythians, Borani and Heruli along the Rhine-Danube rivers and the Black Sea.

Since the time of Marcus Aurelius during the Marcomannic Wars (166/167-189), Germanic-Sarmatian tribes had not exerted such strong pressure along the northern borders of the Roman Empire.

Hungary in its modern (post-1946) borders roughly corresponds to the Great Hungarian Plain (the Carpathian Basin) in Central Europe.

During the Iron Age, it was located at the crossroads between the cultural spheres of Scythian tribes (such as Agathyrsi, Cimmerians), the Celtic tribes (such as the Scordisci, Boii and Veneti), Dalmatian tribes (such as the Dalmatae, Histri and Liburni) and the Germanic tribes (such as the Lugii, Marcomanni). In 44 BC, the Sarmatians, Iazyges moved into the Great Hungarian Plain. In 8 AD, the western part of the territory (the so-called Transdanubia) of modern Hungary formed part of Pannonia, a province of the Roman Empire. Roman control collapsed with the Hunnic invasions of 370–410, the Huns created a significant empire based in present-day Hungary. In 453 they reached the height of their expansion under Attila the Hun. After the death of Attila, the empire collapsed in 455, and Pannonia became part of the Ostrogothic Kingdom. The western part of the Carpathian Basin was occupied by the Longobards and the eastern part by the Gepids. In 567, the Avars occupied the territory ruled by the Gepids. In 568, the Longobards moved to Italy from Transdanubia, and the Avars also occupied that territory, Khagan Bayan I established the Avar Khaganate. The Avars were defeated by the Franks and Bulgars, and their steppe-empire ended around 822.

The Marcomannic Wars (Latin: bellum Germanicum et Sarmaticum, lit. 'German and Sarmatian war') were a series of wars lasting from about AD 166 until 180. These wars pitted the Roman Empire against principally the Germanic Marcomanni and Quadi and the Sarmatian Iazyges; there were related conflicts with several other Germanic, Sarmatian, and Gothic peoples along both sides of the whole length of the Roman Empire's northeastern European border, the river Danube.

The struggle against the Germans and Sarmatians occupied the major part of the reign of Roman emperor Marcus Aurelius, and it was during his campaigns against them that he started writing his philosophical work Meditations.

The Quadi were a Germanic people during the Roman era, who were prominent in Greek and Roman records from about 20 AD to about 400 AD. By about 20 AD they had a kingdom centred in the area of present-day western Slovakia, north of the Roman border on the Danube river. After probably first settling near the Morava river the Quadi expanded their control eastwards over time until they also stretched into present day Hungary. This was part of the bigger region which had been partly vacated a generation earlier by the Celtic Boii, and their opponents the Dacians. The Quadi were the easternmost of a series of four related Suebian kingdoms that established themselves near the river frontier after 9 BC, during a period of major Roman invasions into both western Germania to the northwest of it, and Pannonia to the south of it. The other three were the Hermunduri, Naristi (also known as Varisti), and the Quadi's powerful western neighbours the Marcomanni. Despite frequent difficulties with the Romans, the Quadi survived to become an important cultural bridge between the peoples of Germania to the north, the Roman Empire to the south, and the Sarmatian peoples, most notably the Iazyges, who settled in the same period on the great plain between the Danube and the Tisza rivers.

The Marcomannic wars, during the reign of the emperor Marcus Aurelius and his co-emperors, involved several rounds of particularly destructive conflict against the Quadi and their neighbours, who at one point even invaded Italy itself. By 180 AD when the emperor died on campaign in this region, there were new peace agreements between Rome and the Quadi, but these did not resolve the longer term problems which the region continued to face. Populations from more distant regions periodically disrupted the area, increasing tensions with Rome. Small scale raiding from the neighbouring Sarmatian plain into Roman Pannonia continued, and this played a role in triggering more conflicts between the Quadi and Romans in the third and fourth centuries. However, while the original Marcomanni settlements in the northern Bohemian forest subsequently shrank and became less important, the Quadi thrived near the Danube, and became more culturally integrated with both their Roman and Sarmatian neighbours.

Pannonia Inferior, lit. Lower Pannonia, was a province of the Roman Empire. Its capital was Sirmium. It was one of the border provinces on the Danube. It was formed in the year 103 AD by Emperor Trajan who divided the former province of Pannonia into two parts: Pannonia Superior and Pannonia Inferior. The province included parts of present-day states of Hungary, Serbia, Croatia, and Bosnia and Herzegovina. The province was bordered to the east (across the Danube) by a Sarmatian tribe—the Iazyges. Later, the Vandals appeared to the north-east.
