Slovenia is small, open, export-oriented and subsequently, heavily influenced by international circumstances. It has been severely hurt by the European economic crisis, started in late 2000s. The main economic field is services, followed by industry and construction. Many Slovenians reach top sport successes, particularly in winter sports, water sports, mountaineering, and endurance sports.
Historically, the current territory of Slovenia was part of many different state formations, including the Roman Empire and the Holy Roman Empire, followed by the Habsburg Monarchy. In 1918, the Slovenes exercised self-determination for the first time by co-founding the internationally unrecognized State of Slovenes, Croats, and Serbs, which merged into Yugoslavia. During World War II, Slovenia was occupied and annexed by Germany, Italy, Hungary, and Croatia, only to emerge afterwards as a founding member of the Socialist Federal Republic of Yugoslavia. In June 1991, after the introduction of multi-party representative democracy, Slovenia became an independent country. In 2004, it entered NATO and the European Union, in 2007 became the first former Communist country to join the Eurozone, and in 2010 joined the OECD, a global association of high-income developed countries
