Following centuries of successive habitation by Celts, Romans, 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 to 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. Following the Battle of Mohács in 1526 and about 150 years of partial Ottoman occupation (1541–1699), Hungary came under Habsburg rule, and later formed the great power Austro–Hungarian Empire together with Austria.
