The Iazyges encountered the Basternae and Getae along their migration path sometime around 20AD and turned southward to follow the coast of the Black Sea until they settled in the Danube Delta. This move is attested by the large discrepancy in the location reported by Tacitus relative to that which was earlier given by Ovid. Archeological finds suggest that while the Iazyges took hold of the northern plain between the Danube and the Tisa by around 50AD, they did not take control of the land south of the Partiscum-Lugio line until the late 1st or early 2nd century. The effects of this migration have been observed in the ruins of burial sites left behind by the Iazyges; the standard grave goods made of gold being buried alongside a person were absent, as was the equipment of a warrior; this may have been because the Iazyges were no longer in contact with the Pontic Steppe and were cut off from all trade with them, which had previously been a vital part of their economy. Another problem with the Iazyges' new location was that it lacked both precious minerals and metals, such as iron, which could be turned into weapons. They found it was much more difficult to raid the Romans, who had organized armies around the area, as opposed to the disorganized armies of their previous neighbors. The cutting-off of trade with the Pontic Steppe meant they could no longer trade for gold for burial sites, assuming any of them could afford it. The only such goods they could find were the pottery and metals of the adjacent Dacian and Celtic peoples. Iron weapons would have been exceedingly rare, if the Iazyges even had them, and would likely have been passed down from father to son rather than buried because they could not have been replaced. During the time of Augustus, the Iazyges sent an embassy to Rome to request friendly relations. In a modern context, these "friendly relations" would be similar to a non-aggression pact. 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. 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. Even after being made into a client state, the Iazyges conducted raids across their border with Rome, for example in 6AD and again in 16AD.
