Belarus, officially the Republic of Belarus, formerly known by its Russian name Byelorussia or Belorussia, is a landlocked country in Eastern Europe bordered by Russia to the northeast, Ukraine to the south, Poland to the west, and Lithuania and Latvia to the northwest. Its capital and most populous city is Minsk. Over 40% of its 207,600 square kilometres (80,200 sq mi) is forested. Its major economic sectors are service industries and manufacturing. Until the 20th century, different states at various times controlled the lands of modern-day Belarus, including the Principality of Polotsk (11th to 14th centuries), the Grand Duchy of Lithuania, the Polish–Lithuanian Commonwealth, and the Russian Empire. The parliament of the republic proclaimed the sovereignty of Belarus on 27 July 1990, and during the dissolution of the Soviet Union, Belarus declared independence on 25 August 1991. Belarus's Democracy Index rating is the lowest in Europe and is rated as by far the worst country for press freedom in Europe. More than 80% of the population is ethnic Belarusian, with sizable minorities of Russians, Poles and Ukrainians.
