Semberija (, ) is a geographical region in north-eastern
Bosnia and Herzegovina. The main city in the region is
Bijeljina. Semberija is located between the
Drina and
Sava rivers and
Majevica mountain. Most of the region is situated in the entity of
Republika Srpska, and the smaller part in the entity of
Federation of Bosnia and Herzegovina. Semberija has a very rich history. It was first mentioned in 1533 during the Ottoman rule. During the Austrian rule villages in Semberija were destroyed. The name Semberija is of Hungarian origin and probably related to the time of the 12th-16th centuries when this area was occasionally held by the Hungarian Kingdom. Today about 200,000 people live in the area of Semberija, most in the municipality of Bijeljina.
