The Phoenicians lived in Phoenicia, a narrow coastal region located in what is now Lebanon. Phoenicia was never a unified state, but rather comprised independent city-states, with the most powerful being Byblos, Sidon, and Tyre at different times. The Phoenicians developed advanced seafaring and trade networks and their alphabet influenced many others. They produced glass, textiles, pottery and worked metals. After defeats in the Punic Wars by Rome, Phoenician culture declined and Rome became the dominant power in the Mediterranean.
