By the first century BC, Sarmatians came into direct contact with Rome through Mithridates VI of Pontus. In the employ of the Pontic King, the Sarmatians ran helped bring Asia Minor under his rule, and likely wreaking havoc in Greece and the Balkans, at the expense of Rome. These alliances would eventually be crushed by Pompey and by Caesar in the mid 1st century BC, but the Sarmatians would continue to be a threat to Rome for another several centuries. External pressures from marauding Huns and other eastern people pushed the Sarmatians farther west. The Iazyges, certainly the most commonly known tribe to the Romans, settled along the Danube, between Dacia and Pannonia, soon to be in direct conflict with Rome.
