Throughout much of the peninsula dwelt the Italic tribes. They had migrated around 1000 BC from somewhere within modern Slovenia, near the ancient town of Hallstatt. By 500 BC the strongest of the tribes were the Samnites. Across the Adriatic Sea lived the Illyrians. Sometime around 1000 BC one of their tribes, the Messapians, crossed and established themselves in the heel of the peninsula.
