Bosnia is a very mixed country with 3 major ethnic groups: Bosniaks (also known as Bosnian Muslims), Croats (or Bosnian-Croats) and Serbs (Bosnian-Serbs).
The country is divided into 2 parts: Federation of Bosnia Hercegovina (consists of Bosniak and Croat nationals) and Republika Srpska (consists mainly of Serbs).
Each part obviously is not hemogenous and cities like Mostar and Tuzla have a mixture of peoples.
Other minorities in Bosnia are Roma (also known as Gypsy) and Albanians.
