A Central Asian country of incredible natural beauty and proud nomadic traditions, most of Kyrgyzstan was formally annexed by the Russian Empire in 1876. While initial Russian rule was marked by concessional unrest, the first world war, and the Bolshevik Revolution, Kyrgyzstan had become by 1936 a full Soviet Republic and established part of the broader Soviet state and economy. The country found itself independent in 1991 upon the fall of the USSR and has since undergone a restive period of frequent political change interspersed with intervals of economic development and relative stability. The last decade has seen two presidents, Akaev in 2005 and Bakiev in 2010, ousted as a result of popular demonstrations and at times violent opposition. While political stability looks to have been established following the election of President Atambaev in 2011, concerns remain related to ethnic tension in the south of the country and Kyrgyzstan's economic prospects. Often referred to as the "Switzerland of Central Asia," Kyrgyzstan was a well-established destination for tourists within the Soviet Union, a position that the country has been striving to reach once again in the post-Soviet period.
