 The country was not, however, definitively subdued by the Romans until 9 BC, when it was incorporated into Illyricum, the frontier of which was thus extended as far as the Danube.In AD 6, the Pannonians, with the Dalmatians and other Illyrian tribes, engaged in the so-called Great Illyrian Revolt, and were overcome by Tiberius and Germanicus, after a hard-fought campaign, which lasted for three years.After the rebellion was crushed in AD 9, the province of Illyricum was dissolved, and its lands were divided between the new provinces of Pannonia in the north and Dalmatia in the south.
