Bulgaria (Bulgarian: България), officially the Republic of Bulgaria, is a country on the Balkan Peninsula, in Southern Europe. It borders the Black Sea to the east, Greece and Turkey to the south, Serbia and the Republic of Macedonia to the west, and Romania to the north, mostly along the Danube. Bulgaria also shares a sea border with Turkey, Romania, Ukraine, Russia, and Georgia. The capital is Sofia.

Bulgaria is a country with an ancient history dating back to prehistoric times, the Thracian, Greek and Roman worlds of antiquity, and the powerful medieval Old Great Bulgaria founded in 632 CE and Bulgarian Empire founded in 681 CE. Geographically and climatically, Bulgaria is noted for its diversity, with the landscape ranging from the Alpine snow-capped peaks in Rila, Pirin and the Balkan Mountains to the mild and sunny weather of the Black Sea coast, from the typically continental Danubian Plain (ancient Moesia) in the north to the strong Mediterranean influence in the valleys of Macedonia and the lowlands in the southernmost parts of Thrace.

Bulgaria joined NATO on March 29, 2004 and the European Union on January 1, 2007. The country has been a member of the United Nations since 1955.

Bulgaria comprises portions of the classical regions of Thrace, Moesia, and Macedonia. The southwest of the country is mountainous with two alpine ranges - Rila and Pirin and further east are the lower but more extensive Rhodope Mountains. Rila mountain includes the highest peak of the Balkan Peninsula, peak Musala at 2,925 meters (9,596 ft); the long range of the Balkan mountains runs west-east through the middle of the country, north of the famous Rose Valley. Hilly country and plains are found in the southeast, along the Black Sea coast in the east, and along Bulgaria's main river, the Danube in the north. Other major rivers include the Struma and the Maritsa river in the south.

The Bulgarian climate is temperate, with cold, damp winters and hot, dry summers, and Mediterranean along the Black Sea coast.

The Balkan peninsula derives its name from the Balkan or Stara Planina mountain range which runs through the centre of Bulgaria into eastern Serbia.

Bulgaria's national railroad operator is currently modernizing its fleet Bulgaria occupies a unique and strategically important geographic location. Since ancient times, the country has been a major crossroad between Europe, Asia and Africa. Five of the ten Trans-European corridors run through its territory.

The total length of the roads is 102,016 km of which 93,855 km are paved and 416 km are motorways. Several motorways are planned, under construction or partially built: Trakiya motorway, Hemus motorway, Cherno More motorway, Struma motorway, Maritza motorway and Lyulin motorway. Other motorways are planned but their final track is yet to be decided. They include a link between the capital Sofia and Vidin, a link between the Struma and Trakiya motorways south of Rila Mountain, a link between Rousse and Veliko Tarnovo, and the Sofia ringroad. Many roads have been recently reconstructed.

The length of railways is 6,500 km of which more than 60% are electrified. There is a €360,000,000 project for the modernization and electrification of the Plovdiv-Kapitan Andreevo railway.

Air transportation is relatively well developed. There are four international airports at Sofia, Burgas, Varna and Plovdiv. Massive investment is planned for the first three, a few low-cost airlines are planning new routes to these three airports.

The ports of Varna and Burgas are by far the most important and have the largest turnover. Other than Burgas, Sozopol, Nesebar and Pomorie are big fishing ports. The largest ports on the Danube River are Rousse and Lom which serves the capital.

There is well organised public transport in the cities and in many smaller towns. There are buses, trolleys (in about 20 cities) and trams (in Sofia). The Sofia Metro in the capital is to have 3 lines with total length of about 48 km and 52 stations, but only a section is currently completed.

A country often described to lie at the crossroads linking the East and West, Bulgaria was the centre of Slavic Europe during much of the Middle Ages, exerting considerable literary and cultural influence over the Eastern Orthodox Slavic world by means of the Preslav and Ohrid Literary Schools. Bulgaria is also the birthplace of the Cyrillic alphabet, the second most widely used alphabet in the world, which was developed in these two schools in the tenth century. Bulgaria is well-known for its rich folklore, distinctive traditional music, rituals and tales, but the country's contribution to humanity also continued in the nineteenth and twentieth century, when individuals such as John Atanasoff - born in USA with Bulgarian origin, regarded as the father of the digital computer, a number of noted opera singers (Nicolai Ghiaurov, Boris Christoff, Raina Kabaivanska, Ghena Dimitrova) and successful artists (Christo Javacheff, Pascin, Vladimir Dimitrov) popularized the culture of Bulgaria abroad.

A number of ancient civilizations, most notably the Thracians, Greeks, Romans, Slavs and Bulgars, have left their mark on the culture, history and heritage of Bulgaria. The country has nine UNESCO World Heritage Sites. Of these, two are Thracian tombs (one in Sveshtari and one in Kazanlak), three are monuments of medieval Bulgarian culture (the Boyana Church, the Rila Monastery and the Rock-hewn Churches of Ivanovo), while the Pirin National Park and the Srebarna Nature Reserve represent the country's natural beauty, and the ancient city of Nesebar is a unique combination of European cultural interaction, as well as, historically, one of the most important centres of naval trade in the Black Sea. In addition, the Varna Necropolis, a 3200-3000 BC burial site, contains what are believed to be the oldest examples of worked gold in the world.

In winter, Borovets, Bansko and Pamporovo are ski resorts. There are summer resorts on the Black Sea at Sozopol, Nessebur, Golden Sands, Sunny Beach, Sveti Vlas, Albena, St. St. Constantine & Helena and many others. Spa resorts such as Bankya, Hisarya, Sandanski, Velingrad, Varshets and many others are popular all over the year. Bulgaria is becoming an attractive destination because of the quality of the resorts and prices below those found in Western Europe.

Bulgaria has enjoyed a substantial growth in income from international tourism over the past decade. Beach resorts are popular with tourists from Germany, Russia, Scandinavia and the United Kingdom. The ski resorts are a favourite destination for British and Irish tourists.
