Hungary is a country in Central Europe that covers an area of 93,030 square kilometres in the Carpathian Basin, bordered by 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, a significant economic hub, classified as a leading global city. Major urban areas include Debrecen, Szeged, Miskolc, Pécs and Győr.
Following centuries of successive habitation by Celts, Romans, West Slavs, Gepids and Avars, the foundation of Hungary was laid in the late 9th century by the Hungarian grand prince Árpád in the conquest of the Carpathian Basin. His great-grandson Stephen I ascended the throne in 1000, converting the country to a Christian kingdom. By the 12th century, Hungary became a middle power within the Western world, reaching a golden age by the 15th century.
