Introduction & Background
Croatia (/kroʊˈeɪʃə/ⓘ, kroh-AY-shə; Template:Lang-hr, Template:IPA-hr), officially the Republic of Croatia (Template:Lang-hr, (listenⓘ)),e is a country at the crossroads of Central and Southeast Europe. Its sole coast is on the Adriatic Sea. It borders Slovenia to the northwest, Hungary to the northeast, Serbia to the east, Bosnia and Herzegovina and Montenegro to the southeast, and shares a maritime border with Italy to the west and southwest. Its capital and largest city, Zagreb, forms one of the country's primary subdivisions, with twenty counties. The country spans 56,594 square kilometres (21,851 square miles), and has a population of nearly 3.9million.
The Croats arrived in the late 6th century. By the 9th century, they had organized the territory into two duchies. Croatia was first internationally recognized as independent on 7 June 879 during the reign of Duke Branimir. Tomislav became the first king by 925, elevating Croatia to the status of a kingdom. During the succession crisis after the Trpimirović dynasty ended, Croatia entered a personal union with Hungary in 1102. In 1527, faced with Ottoman conquest, the Croatian Parliament elected Ferdinand I of Austria to the Croatian throne. In October 1918, the State of Slovenes, Croats and Serbs, independent from Austria-Hungary, was proclaimed in Zagreb, and in December 1918, merged into the Kingdom of Yugoslavia. Following the Axis invasion of Yugoslavia in April 1941, most of Croatia was incorporated into a Nazi-installed puppet state, the Independent State of Croatia. A resistance movement led to the creation of the Socialist Republic of Croatia, which after the war became a founding member and constituent of the Socialist Federal Republic of Yugoslavia. On 25 June 1991, Croatia declared independence, and the War of Independence was successfully fought over the next four years.
