Carniola is a historical region that comprised parts of present-day Slovenia. Although as a whole it does not exist anymore, Slovenes living within the former borders of the region still tend to identify with its traditional parts Upper Carniola, Lower Carniola, and to a lesser degree with Inner Carniola. In 1991, 47% of the population of Slovenia lived within the borders of the former Duchy of Carniola.

Slovenia officially the Republic of Slovenia, is a country in southern Central Europe. Slovenia is bordered by Italy to the west, Austria to the north, Hungary to the northeast, Croatia to the south and southeast, and a short coastline within the Adriatic Sea to the southwest. Slovenia is mostly mountainous and forested, covers 20,271 square kilometres (7,827 sq mi), and has a population of approximately 2.1 million. Slovene, a South Slavic language, is the official language. Slovenia has a predominantly temperate continental climate, with the exception of the Slovene Littoral and the Julian Alps. A sub-mediterranean climate reaches to the northern extensions of the Dinaric Alps that traverse the country in a northwest–southeast direction. The Julian Alps in the northwest have an alpine climate. Toward the northeastern Pannonian Basin, a continental climate is more pronounced. Ljubljana, the capital and largest city of Slovenia, is geographically situated near the centre of the country.
