Slovenia, officially the Republic of Slovenia, is a coastal Alpine country in southern Central Europe bordering Italy on the west, the Adriatic Sea on the southwest, Croatia on the south and east, Hungary on the northeast, and Austria on the north. The capital of Slovenia is Ljubljana.

At various points in Slovenia's history, the country has been part of the Roman Empire, the Duchy of Carantania (only modern Slovenia's northern part), the Holy Roman Empire, Austria-Hungary, the State of Slovenes, Croats and Serbs, the Kingdom of Serbs, Croats and Slovenes (renamed the Kingdom of Yugoslavia in 1929) between the World Wars, and the SFR of Yugoslavia from 1945 until gaining independence in 1991. Slovenia is a member of the European Union, the Council of Europe, NATO, and has observer status in La Francophonie.

Four major European geographic regions meet in Slovenia: the Alps, the Dinarides, the Pannonian plain, and the Mediterranean. Slovenia's highest peak is Triglav (2,864 m; 9,396 ft); the country's average height above the sea level is 557 metres (1,827 ft). Around one half of the country (11,691 km²; 4,514 sq mi) is covered by forests; this makes Slovenia the third most forested country in Europe, after Finland and Sweden. Remnants of primeval forests are still to be found, the largest in the Kocevje area. Grassland covers 5,593 square kilometres (2,159 sq mi) of the country and fields and gardens 2,471 square kilometres (954 sq mi). There are also 363 square kilometres (140 sq mi) of orchards and 216 square kilometres (83 sq mi) of vineyards.

Its climate is Submediterranean on the coast, Alpine in the mountains and continental with mild to hot summers and cold winters in the plateaus and valleys to the east. The average temperatures are -2°C (28°F) in January and 21°C (70°F) in July. The average rainfall is 1,000 millimetres (39.4 in) for the coast, up to 3,500 millimetres (137.8 in) for the Alps, 800 millimetres (31.5 in) for south east and 1,400 millimetres (55.1 in)for central Slovenia.

Although located on the shore of the Mediterranean Sea, most of Slovenia is in the Black Sea drainage basin. The geometric center of gravity of Slovenia is located at the geographic coordinates 46°07'11,8" N and 14°48'55,2" E. It lies in Spodnja Slivna near Vace in the municipality of Litija.

Slovenia's first book was printed by the Protestant reformer Primož Trubar (1508-1586). It was actually two books, Catechismus (a catechism) and Abecedarium, which was published in 1550 in Tübingen, Germany.

The central part of the country, namely Carniola (which existed as a part of Austria-Hungary until the early twentieth century) was ethnographically and historically well-described in the book The Glory of the Duchy of Carniola (German: Die Ehre deß Herzogthums Crain, Slovenian: Slava vojvodine Kranjske), published in 1689 by Baron Janez Vajkard Valvasor (1641-1693).

Slovenia's two greatest writers were the poet France Prešeren (1800-1849) and writer Ivan Cankar (1876-1918). The most important Slovenian painters are Ivana Kobilca and impressionist Rihard Jakopic. The most famed Slovenian architect is Jože Plecnik who worked in Vienna as well as in Prague.

Slovenia is a homeland of numerous musicians and composers, including Renaissance composer Jacobus Gallus (1550-1591), who greatly influenced Central European classical music. In the twentieth century, Bojan Adamic was a renowned film music composer.

Contemporary popular musicians have been Slavko Avsenik, Laibach, Vlado Kreslin, Zoran Predin, Pero Lovšin, Silence, New Swing Quartet, DJ Umek, Melodrom, Siddharta, Magnifico and others.

Slovenian cinema has more than a century-long tradition with Karol Grossmann, Janko Ravnik, Ferdo Delak, France Štiglic, Mirko Grobler, Igor Pretnar, France Kosmac, Jože Pogacnik, Matjaž Klopcic, Jane Kavcic, Jože Gale, Boštjan Hladnik and Karpo Godina as its most established filmmakers. Contemporary film directors Janez Burger, Jan Cvitkovic, Damjan Kozole, Janez Lapajne and Maja Weiss are most notable representatives of the so-called "Renaissance of Slovenian cinema".

Slovenia's learned men include chemist and Nobel prize laureate Friderik Pregl, physicist Jožef Stefan, philosopher Slavoj Žižek, linguist Franc Miklošic, physician Anton Marko Plencic, mathematician Jurij Vega, rocket engineer and pioneer of cosmonautics Herman Potocnik.
