The term Greater Serbia or Great Serbia (, Velika Srbija) applies to the Serbian nationalist and irredentist ideology directed towards the creation of a Serbian land which would incorporate all regions of traditional significance to the Serbian nation, and regions outside of Serbia that are populated mostly by Serbs. This movement's main ideology is to unite all Serbs (or all historically ruled or Serb populated lands) into one state, claiming, depending on the version, different areas of many surrounding countries.
