Jenin is believed to have been built on the site of the ancient city of Ein-Ganam, mentioned in the Egyptian Amarna tablets (see Tell el Amarna), or the biblical town of Ginnat. Once the site of a Byzantine church, now in ruins, Jenin was captured by Christian knights during the Crusades. The town was used as a Turkish-German army base during World War I, became part of the Palestine mandate (1923–48), and was annexed (1950) by Jordan. A center of Palestinian guerrilla activity after the 1948 Arab-Israeli war, Jenin was occupied by Israel from the Six-Day War (1967) until 1995, when it came under Palestinian control. Jenin was the center of fierce Israeli-Palestinian fighting in 2002, when the town was heavily damaged.
