Hungary is a country in Central Europe. Spanning 93,030 square kilometres (35,920 sq mi) in the Carpathian Basin, it borders Slovakia to the north, Ukraine to the northeast, Romania to the east and southeast, Serbia to the south, Croatia and Slovenia to the southwest, and Austria to the west. With about 10 million inhabitants, Hungary is a medium-sized member state of the European Union. The official language is Hungarian, which is the most widely spoken Uralic language in the world, and among the few non-Indo-European languages to be widely spoken in Europe. Hungary's capital and largest city is Budapest; other major urban areas include Debrecen, Szeged, Miskolc, Pécs, and Győr.
The Austro-Hungarian Empire collapsed after World War I, and the subsequent Treaty of Trianon established Hungary's current borders, resulting in the loss of 71% of its territory, 58% of its population, and 32% of ethnic Hungarians. Following the tumultuous interwar period, Hungary joined the Axis Powers in World War II, suffering significant damage and casualties. Postwar Hungary became a satellite state of the Soviet Union, which contributed to the establishment of a socialist republic spanning four decades (1949 - 1989). Following the failed 1956 revolution against the Soviet-backed government, Hungary became a comparatively freer, though still repressive, member of the Eastern Bloc. The seminal opening of the previously-restricted border with Austria in 1989 accelerated the collapse of the Eastern Bloc, and subsequently the Soviet Union. On 23 October 1989, Hungary became a democratic parliamentary republic.
Hungary is considered a developed country with a high-income economy and a very high Human Development Index. Hungarians enjoy universal health care and tuition-free secondary education. Hungary's cultural history includes significant contributions to its arts, music, literature, sports, science and technology. It is the thirteenth-most popular tourist destination in Europe, drawing 15.8 million international tourists in 2017, owing to attractions such as the largest thermal water cave system in the world, second largest thermal lake, the largest lake in Central Europe and the largest natural grasslands in Europe.
Hungary's cultural, historical, and academic prominence classify it as a middle power in global affairs. Hungary joined the European Union in 2004 and has been part of the Schengen Area since 2007. It is a member of numerous international organisations, including the United Nations, NATO, WTO, World Bank, IIB, the AIIB, the Council of Europe, and the Visegrád Group.
