Hungary (Hungarian: Magyarország [ˈmɒɟɒrorsaːɡ] (listen)) 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, Austria to the northwest, Romania to the east, Serbia to the south, Croatia to the southwest, and Slovenia 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. Hungary's capital and its largest city and metropolis is Budapest. Other major urban areas include Debrecen, Szeged, Miskolc, Pécs and Győr.
The territory of modern Hungary was for centuries inhabited by a succession of peoples, including Celts, Romans, Germanic tribes, Huns, West Slavs and the Avars. The foundations of the Hungarian state was established in the late ninth century AD by the Hungarian grand prince Árpád following the conquest of the Carpathian Basin. His great-grandson Stephen I ascended the throne in 1000, converting his realm to a Christian kingdom. By the 12th century, Hungary became a regional power, reaching its cultural and political height in the 15th century. Following the Battle of Mohács in 1526, Hungary was partially occupied by the Ottoman Empire (1541–1699). It came under Habsburg rule at the turn of the 18th century, and later joined Austria to form the Austro–Hungarian Empire, a major European power.
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. Hungary became a satellite state of the Soviet Union, which contributed to the establishment of a socialist republic spanning four decades (1949–1989). The country gained widespread international attention as a result of its 1956 revolution and the seminal opening of its previously-restricted border with Austria in 1989, which accelerated the collapse of the Eastern Bloc. On 23 October 1989, Hungary became a democratic parliamentary republic.
In the 21st century, Hungary is a middle power and has the world's 57th largest economy by nominal GDP, as well as the 58th largest by PPP, out of 191 countries measured by IMF. As a substantial actor in several industrial and technological sectors, it is the world's 35th largest exporter and 34th largest importer of goods. Hungary is an OECD high-income economy with a very high standard of living. It keeps up a social security and universal health care system, and a tuition-free university education. Hungary performs well in international rankings: it is 20th in quality of life, 24th in the Good Country Index, 28th in inequality-adjusted human development, 32nd in the Social Progress Index, 33rd in the Global Innovation Index and ranks as the 15th safest country in the world.
Hungary joined the European Union in 2004 and has been part of the Schengen Area since 2007. Hungary is a member of the United Nations, NATO, WTO, World Bank, the AIIB, the Council of Europe, the Visegrád Group and more. Well known for its rich cultural history, Hungary has contributed significantly to arts, music, literature, sports and science and technology. Hungary is the 11th most popular country as a tourist destination in Europe, attracting 14.3 million international tourists in 2015. It is home to the largest thermal water cave system and the second largest thermal lake in the world, the largest lake in Central Europe and the largest natural grasslands in Europe.
