who ruled the country before it became bolivia
History of Bolivia After the fall of Tiwanaku empire, the many Aymara Lake Titicaca were conquered by the Inca empire. Prior to the Spanish conquest, the Andean province of Qullasuyu was a part of the Inca empire, while the northern and eastern lowlands were inhabited by independent nomadic tribes. Spanish conquistadors, arriving from Cuzco and Asunción took control of the region in the 16th century. 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 Simón Bolívar, 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.
Inca Empire From 1438 to 1533, the Incas incorporated a large portion of western South America, centered on the Andean Mountains, using conquest and peaceful assimilation, among other methods. At its largest, the empire joined Peru, large parts of modern Ecuador, western and south central Bolivia, northwest Argentina, north and central Chile and a small part of southwest Colombia into a state comparable to the historical empires of Eurasia. Its official language was Quechua.[6] Many local forms of worship persisted in the empire, most of them concerning local sacred Huacas, but the Inca leadership encouraged the sun worship of Inti – their sun god – and imposed its sovereignty above other cults such as that of Pachamama.[7] The Incas considered their king, the Sapa Inca, to be the "son of the sun."[8]
