town, Tokat il (province), east-central Turkey. Lying in a fertile plain crossed by the Yeşil River, the town is at the foot of a hill crowned by a ruined citadel. Zela, the ancient temple state of Pontus, was famous as the site where in 47 BC the Roman general Julius Caesar (Caesar, Julius) defeated Pharnaces II, son of Mithradates VI of Pontus; when informing the Senate of his victory, Caesar wrote, “Veni, vidi, vici” (“I came, I saw, I conquered”).

The town is an important local commercial and agricultural market for such regional products as cereals and sugar beets. The latter are sent to a refinery at nearby Turhal. Zile is linked by highways with the cities of Tokat and Amasya and is near the Sivas-Samsun railway. Pop. (2000) 52,640.
