Bosnia and Herzegovina sometimes called Bosnia-Herzegovina, or simply Bosnia, is a country in Southeastern Europe, on the Balkan Peninsula. Its capital and largest city is Sarajevo. Bordered by Croatia to the north, west and south, Serbia to the east, and Montenegro to the southeast, Bosnia and Herzegovina is almost landlocked, except for the 20 kilometres (12 miles) of coastline on the Adriatic Sea surrounding the town of Neum. In the central and southern interior of the country the geography is mountainous, in the northwest it is moderately hilly, and the northeast is predominantly flatland. The inland is a geographically larger region and has a moderate continental climate, bookended by hot summers and cold and snowy winters. The southern tip of the country has a Mediterranean climate and plain topography.
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 civilizations. Culturally, politically and socially, the country has one of the richest histories in the region, having been first settled by the Slavic peoples that populate the area today from the 6th through to the 9th centuries AD. They then established the first independent banate in the region, known as the Banate of Bosnia, in the early 12th century upon the arrival and convergence of peoples that would eventually come to call themselves Dobri Bošnjani ("Good Bosnians"). This 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. Following the dissolution of the Socialist Federal Republic of Yugoslavia, the country proclaimed independence in 1992,
