As you can see on the Bolivia map that Bolivia is a landlocked country in South America that shares international boundaries from all sides. Brazil shares its boundary from the north and east, Paraguay and Argentina from south, and Chile and Peru from the west. The government type of Bolivia is a Democratic Republic, which is divided into nine departments. Bolivia's constitution is drafted very recently i.e. in the year 2006-07 and approved only in 2009.
During most of the Spanish colonial rule, Bolivia was known as Upper Peru and administered by the Royal Audiencia of Charcas. After the first call for independence in 1809, 16 years of war followed before the establishment of the Bolivian Republic, named for the Liberator SimÃ³n BolÃ­var, on August 6, 1825. Since then Bolivia has endured regular periods of political and economic instability, including the loss of various provinces to its neighbors, such as Acre, parts of the Gran Chaco and its Pacific coast, making it a land-locked country.
