Macedonia, officially the Republic of Macedonia, is a country in the Balkan peninsula in Southeast Europe. It is one of the successor states of the former Yugoslavia, from which it declared independence in 1991. It became a member of the United Nations in 1993, but, as a result of an ongoing dispute with Greece over the use of the name "Macedonia", was admitted under the provisional description the former Yugoslav Republic of Macedonia, a term that is also used by international organizations such as the European Union, the Council of Europe, and NATO.
A landlocked country, the Republic of Macedonia has borders with Kosovo to the northwest, Serbia to the north, Bulgaria to the east, Greece to the south, and Albania to the west. It constitutes approximately the northwestern third of the larger geographical region of Macedonia, which also comprises the neighbouring parts of northern Greece and smaller portions of southwestern Bulgaria and southeastern Albania. The country's geography is defined primarily by mountains, valleys, and rivers. The capital and largest city, Skopje, is home to roughly a quarter of the nation's 2.06 million inhabitants.
