Zile, anciently known as Zela (Greek: Ζῆλα) (still as Latin Catholic titular see), is a city in Tokat Province, Turkey.

The city has a long history, including as former bishopric and the site of the Battle of Zela, which prompted the phrase "Veni, vidi, vici.

After roughly 200 years of Persian rule, Alexander the Great captured Zela from Darius III of Persia as a result of the Battle of the Granicus (334 BC).

As a consequence, King Mithridates VI of Pontus attacked and took Zela in 88 BC, and ordered the killing of all Romans living there.

In Pompey's settlement of Pontus, Zela received a civic constitution and a sizable territory thus transforming from its previous status as a temple domain to a city.

Under Byzantine rule, Zile became a (now Titular Latin) bishopric of Asia Minor, suffragan of Amasya in the former Roman province of Helenopontus (see below).

As a result of heavy bombardment, Zile suffered a great fire which led to the loss of two thirds of its infrastructure and most of its forest cover.

Zela, in the Roman province of Helenopontus (civil diocese of Pontus), was a suffragan of the Metropolitan Archdiocese of Amasea, in the sway of the Patriarchate of Constantinople.

The following Suffragan Bishops of Zela are historically documented : The diocese was nominally restored no later than the 18th century as Latin Titular bishopric of Zela (Latin = Curiate Italian) / Zeliten(us) It has been vacant for decades, having had the following incumbents: There are several columns in the center of the castle, but some researchers claim that the actual column with Caesar's famous words was stolen, and the thieves have not been found yet.

Mast Tumulus, an ancient site located in Zile, is of special importance since it hosts the palace of a Hittitite ruler, earthenware utensils and Hittite hieroglyphics.

[15] Zile covers an area of 1,512 square kilometres (584 sq mi) within its city limits and has an elevation of 710 metres (2,330 ft).

The city is mostly surrounded by a fertile plain called Zile Ovası crossed by the Yeşil River and can produce harvests twice a year.

[17] Zile's weather is influenced by the narrow coast land of the Black Sea Region to the north, bringing humidity, and by the Central Anatolia inland plateau to the south, with its low rainfall and cold winters.

Zile is a center of cereal production such that she is one of the biggest exporters of wheat, barley, lentil and common vetch in the Black Sea region.

People of Zile don't use their grapes to produce wine, but pekmez - a syrup-like liquid mixed from different kinds of fruit-juices.

The students of Zile Dinçerler School of Tourism and Hotel Management of Gaziosmanpasha University play an important role in city's economic activities.

Anatolian Tigers constructed 55 factories whose major products include textiles, sugar beet, furniture, tomato sauce, leblebi, marble and shoes.
