The borders of contemporary Lebanon are a product of the Treaty of Sèvres of 1920. Its territory was in the core of the Bronze Age Canaanite (Phoenician) city-states. As part of the Levant, it was part of numerous succeeding empires throughout ancient history, including the Egyptian, Assyrian, Babylonian, Achaemenid Persian, Hellenistic, Roman and Sasanid Persian empires.
