Modern Slovenia dates its statehood to 25 June 1991, when, following a plebiscite held on 23 December 1990 in which 88.5 per cent of all eligible voters chose independence, the Slovenian parliament adopted the Basic Constitutional Charter on the Sovereignty and Independence of the Republic of Slovenia together with a formal Declaration of Independence. The move made Slovenia, with Croatia, the first of Yugoslavia's republics to break away. It provoked the intervention of the Yugoslav People's Army and the Ten-Day War of 27 June to 7 July 1991, which the Slovene Territorial Defence won; the Brioni Declaration of 7 July halted the fighting and led to the withdrawal of federal forces. The deeper roots of Slovene identity reach back to the early Slavic principality of Carantania and to the founding of the literary language by the Protestant reformer Primoz Trubar in 1550. Slovenia's history is the long story of a small Alpine and Adriatic people who preserved a distinct language and identity through more than a thousand years of foreign rule. Slavic ancestors settled the eastern Alps in the sixth and seventh centuries and organised the early principality of Carantania, remembered for its ritual enthronement of dukes in the Slovene tongue. From the late Middle Ages the Slovene lands were gathered into the Habsburg duchies of Carniola, Styria and Carinthia, and remained under Austrian rule for some six centuries. The Reformation gave the Slovenes their first printed books, when Primoz Trubar published a catechism and a primer in 1550 and founded a literary language. Napoleon's short-lived Illyrian Provinces, with Ljubljana as their capital, and a nineteenth-century cultural awakening led by the poet France Preseren prepared the way for modern nationhood. After the fall of Austria-Hungary in 1918 the Slovenes joined the Yugoslav state, becoming after 1945 the most prosperous republic of socialist Yugoslavia, before declaring independence on 25 June 1991 and winning it in the brief Ten-Day War. Slovenia joined NATO and the European Union in 2004 and adopted the euro in 2007.
