Ithobaal I (in Hebrew Ethbaal, 1 Kings 16:31) was a king of Tyre who founded a new dynasty. During his reign, Tyre expanded its power on the mainland, making all of Phoenicia its territory as far north as Beirut, including Sidon, and even a part of the island of Cyprus. At the same time, Tyre also built new overseas colonies: Botrys (now Batrun) near Byblos, and Auza in Libya.
