Montenegro (Serbian: Црна Гора or Crna Gora, pronounced /'t͡sr̩na: 'ɡɔra/, listen ), officially the Republic of Montenegro (Република Црна Гора or Republika Crna Gora), is a country located in Southeastern Europe. It has a coast on the Adriatic Sea to the south, and borders Croatia on the west, Bosnia and Herzegovina on the northwest, Serbia on the northeast and Albania on the southeast. Its de facto capital and largest city is Podgorica, while Cetinje is designated as Prijestonica, the old royal capital or seat of the throne.
De facto independent since the late Middle Ages, and an internationally recognised country from 1878 until 1918, Montenegro was later a part of various incarnations of Yugoslavia and the state union of Serbia and Montenegro. Based on the results of the referendum held on May 21, 2006, Montenegro declared independence on June 3, 2006. On June 28, 2006, it became the 192nd member state of the United Nations, and on May 11, 2007, the 47th member state of the Council of Europe.
