Greater Serbia

The term Greater Serbia or Great Serbia (Serbian: Велика Србија/Velika Srbija) describes the Serbian nationalist and irredentist ideology of the creation of a Serb state which would incorporate all regions of traditional significance to Serbs, including regions outside Serbia that are populated by Serbs. The initial movement's main ideology (Pan-Serbism) was to unite all Serbs (or all territory historically ruled or populated by Serbs) into one state, claiming, depending on the version, different areas of many surrounding countries.

The Greater Serbian ideology includes claims to territories in modern-day Croatia, Bosnia and Herzegovina, Montenegro, and the Republic of Macedonia. In some historical forms, Greater Serbian aspirations also include parts of Albania, Bulgaria, Greece (Thessaloniki, Macedonia), Hungary and Romania. Its inspiration comes from the memory and existence of the relatively large and powerful Serbian Empire that existed in 14th century Southeastern Europe prior to the Ottoman conquest of the Balkans. The term "Serbian imperialism" has been used mainly for the aspirations of the Kingdom of Serbia.

Following the growing nationalistic tendency in Europe from the 18th century onwards, such as the Unification of Italy, Serbia – after first gaining its principality within the Ottoman Empire in 1817 – experienced a popular desire for full unification with the Serbs of the remaining territories, mainly those living in neighbouring entities.
