Tribalia

Timočka Krajina (Serbian Cyrillic: Тимочка Крајина, Romanian: Valea Timocului or Tribalia) is a geographical region in east-central Serbia around the Timok River. Its name means "Timok frontier". Timočka Krajina corresponds to two Serbian districts (Bor and Zaječar), with a total 2002 census population of 284,112.

Timok derives its name from the ancient district of Timachion (Τιμάχιον in Ancient Greek) from Hellenistic and Roman times. Its name means "the Timacus frontier". The region was named due to its location around the Timacus or Timok River and near the state border (hence the name "krajina" - "frontier" in English). In Serbian, the region is known as Timočka Krajina (Тимочка Крајина), in Romanian Valea Timocului (Timoc Valley). In Bulgarian it is known as Timoshko (Тимошко).

Timočka Krajina roughly corresponds to the Bor and Zaječar districts of Serbia. It includes seven municipalities and one city:

The largest city in the region is Zaječar, and therefore functions as its cultural, urban, and economic centre. It consists of four municipalities: Stari grad (old parts of the city: Vlačić, Kraljevica, Karađorđev venac, Šljivarsko brdo, Lubničko brdo, Oskoruša, Pazaršte, Zvezdan, Podliv, Veliki izvor), Kotlujevac (Ključ 1,2,3,4, Živinarnik, Selište, Vlaško brdo, Beli breg), Grljan (south suburban parts and Višnjar) and Salaš (north suburban parts). The largest ethnic group in Zaječar is Koltlujevac, with a population of over 25,000.
