Bosnia and Herzegovina is a region that traces permanent human settlement back to the Neolithic age, during and after which it was populated by several Illyrian and Celtic civilizations. Culturally, politically, and socially, the country has a rich history, having been first settled by the Slavic peoples that populate the area today from the 6th through to the 9th centuries. In the 12th century the Banate of Bosnia was established, which evolved into the Kingdom of Bosnia in the 14th century, after which it was annexed into the Ottoman Empire, under whose rule it would remain from the mid-15th to the late 19th centuries. The Ottomans brought Islam to the region, and altered much of the cultural and social outlook of the country. This was followed by annexation into the Austro-Hungarian Monarchy, which lasted up until World War I. In the interwar period, Bosnia was part of the Kingdom of Yugoslavia and after World War II, the country was granted full republic status in the newly formed Socialist Federal Republic of Yugoslavia. Following the dissolution of Yugoslavia, the country proclaimed independence in 1992, which was followed by the Bosnian War, lasting until late 1995.
