Southeast Europe or Southeastern Europe (SEE) is a geographical region of Europe, consisting primarily of the coterminous Balkan Peninsula. There are overlapping and conflicting definitions as to where exactly Southeastern Europe begins or ends or how it relates to other regions of the continent. Sovereign states and territories that are included in the region are, in alphabetical order: Albania, Bosnia and Herzegovina, Bulgaria, Croatia, Greece, Kosovo, Montenegro, North Macedonia, Romania, Serbia, and East Thrace (part of Turkey). Sometimes, Moldova and Slovenia are also included. The largest city of the region is Istanbul (which straddles the Bosporus strait between Southeast Europe and Western Asia), followed by Bucharest, Sofia, Belgrade, and Athens.
