Albania ( (listen) a(w)l-BAY-nee-ə; Albanian: Shqipëri or Shqipëria; Gheg Albanian: Shqipni or Shqipnia also Shqypni or Shqypnia), officially the Republic of Albania (Albanian: Republika e Shqipërisë, pronounced [ɾɛpuˈblika ɛ ʃcipəˈɾiːsə]), is a country in Southeast Europe on the Adriatic and Ionian Sea within the Mediterranean Sea. It shares land borders with Montenegro to the northwest, Kosovo to the northeast, North Macedonia to the east, Greece to the south and a maritime border with Italy to the west.
Geographically, the country displays varied climatic, geological, hydrological and morphological conditions, defined in an area of 28,748 km2 (11,100 sq mi). It possesses remarkable diversity with the landscape ranging from the snow-capped mountains in the Albanian Alps as well as the Korab, Skanderbeg, Pindus and Ceraunian Mountains to the hot and sunny coasts of the Albanian Adriatic and Ionian Sea along the Mediterranean Sea.
Historically, the area of Albania was populated by various Illyrian, Thracian and Ancient Greek tribes as well as several Greek colonies established in the Illyrian coast. The area was annexed in the 3rd century by Romans and became an integral part of the Roman provinces of Dalmatia, Macedonia and Illyricum. The autonomous Principality of Arbër emerged in 1190, established by archon Progon in the Krujë, within the Byzantine Empire. In the late thirteenth century, Charles of Anjou conquered Albanian territories from the Byzantines and established the medieval Kingdom of Albania, which at its maximal extension was extending from Durrës along the coast to Butrint in the south. In the mid-fifteenth century, it was conquered by the Ottomans.
The modern nation state of Albania emerged in 1912 following the defeat of the Ottomans in the Balkan Wars. The modern Kingdom of Albania was invaded by Italy in 1939, which formed Greater Albania, before becoming a Nazi German protectorate in 1943. After the defeat of Nazi Germany, a Communist state titled the People's Socialist Republic of Albania was founded under the leadership of Enver Hoxha and the Party of Labour. The country experienced widespread social and political transformations in the communist era, as well as isolation from much of the international community. In the aftermath of the Revolutions of 1991, the Socialist Republic was dissolved and the fourth Republic of Albania was established.
Politically, the country is a unitary parliamentary constitutional republic and developing country with an upper-middle income economy dominated by the tertiary sector followed by the secondary and primary sector. It went through a process of transition, following the end of communism in 1990, from a centralized to a market-based economy. It also provides universal health care and free primary and secondary education to its citizens.
The country is a member of the United Nations, World Bank, UNESCO, NATO, WTO, COE, OSCE and OIC. It is also an official candidate for membership in the European Union. In addition it is one of the founding members of the Energy Community, including the Organization of the Black Sea Economic Cooperation and Union for the Mediterranean.
