Bosnia and Herzegovina
Bosnia and Herzegovina ( or ; Serbo-Croatian: Bosna i Hercegovina [BiH] / Боснa и Херцеговина [БиХ]), sometimes called Bosnia–Herzegovina, and often known informally as Bosnia, is a country in Southeastern Europe, located within the Balkan Peninsula. Sarajevo is the capital and largest city.
Bosnia and Herzegovina is an almost landlocked country – it has a narrow coast at the Adriatic Sea, about 20 km long surrounding the town of Neum. It is bordered by Croatia to the north, west and south; Serbia to the east; and Montenegro to the southeast. In the central and eastern interior of the country the geography is mountainous, in the northwest it is moderately hilly, and the northeast is predominantly flatland. The inland, Bosnia, is a geographically larger region and has a moderate continental climate, with hot summers and cold and snowy winters. The southern tip, Herzegovina, has a Mediterranean climate and plain topography.
Montenegro ( / Crna Gora ) is a country in Southeastern Europe on the Adriatic Sea. It borders Bosnia and Herzegovina to the northwest; Serbia and Kosovo to the east, Albania to the south and Croatia to the southwest. Montenegro has an area of 13,812 square kilometres and a population of 620,079 (2011 census). Its capital Podgorica is one of the twenty-three municipalities in the country. Cetinje is designated as the Old Royal Capital.
During the Early Medieval period, three principalities were located on the territory of modern-day Montenegro: Duklja, roughly corresponding to the southern half; Travunia, the west; and Rascia proper, the north. In 1042, archon Stefan Vojislav led a revolt that resulted in the independence of Duklja from the Byzantine Empire and the establishment of the Vojislavljević dynasty. The independent Principality of Zeta emerged in the 14th and 15th centuries, ruled by the House of Balšić between 1356 and 1421, and by the House of Crnojević between 1431 and 1498, when the name Montenegro started being used for the country. After falling under Ottoman rule, Montenegro regained de facto independence in 1697 under the rule of the House of Petrović-Njegoš, first under the theocratic rule of prince-bishops, before being transformed into a secular principality in 1852. Montenegro's de jure independence was recognised by the Great Powers at the Congress of Berlin in 1878, following the Montenegrin–Ottoman War. In 1905, the country became a kingdom. After World War I, it became part of Yugoslavia. Following the breakup of Yugoslavia, the republics of Serbia and Montenegro together established a federation known as the Federal Republic of Yugoslavia, which was renamed State Union of Serbia and Montenegro in 2003. On the basis of an independence referendum held in May 2006, Montenegro declared independence and the federation peacefully dissolved on 3 June of that year.
