By about A.D. 1100 the principal inhabitants of the western part of present-day Burkina Faso were the Bobo, Lobi, and Gurunsi. Invaders from present-day Ghana conquered central and E Burkina Faso, establishing the Mossi states of Ouagadougou, Yatenga, and Tengkodogo in the center and the state of Gourma in the east. The conquerors were far outnumbered by their subjects, but by using religion (based on ancestor worship) and a complex administrative system (which allowed for some local autonomy) they created powerful states that endured for more than 500 years. Ouagadougou was headed by the Morho Naba and at its peak was divided into several provinces, which were subdivided into a total of about 300 districts. The Mossi states had strong armies, which included cavalry units, and were able to repel most attacks by the Mali and Songhai empires during the period from the 14th to 16th cent.
Near the end of the 19th-century scramble for African territory among the European powers, France gained control over the region. In 1895 the French peacefully negotiated a protectorate over Yatenga; in 1896 they forcefully occupied Ouagadougou; and in 1897 they annexed Gourma and the lands of the Bobo, Lobi, and Gurunsi peoples. An Anglo-French agreement in 1898 established the boundary with the Gold Coast (now Ghana).
The region of present-day Burkina Faso was administered as part of the French colony of Soudan (then called Upper Senegal-Niger and now mostly part of Mali) until 1919, when it was made a separate protectorate as Upper Volta. In 1932, it was divided among Côte d'Ivoire, Soudan, and Niger for administrative convenience. In 1947, Upper Volta was reestablished as a separate territory within the French Union, and in 1958 it became an autonomous republic within the French Community.
On Aug. 5, 1960, Upper Volta achieved full independence. The constitution of 1960 established a strong presidential government, and Maurice Yaméogo of the Voltaic Democratic Union (UDV) became the first president. He reduced the traditional power of the Mossi states, but his authority was weakened by ethnic conflicts and the poor performance of the economy. In late 1965, Yaméogo was overwhelmingly reelected president, but in Jan., 1966, at the height of demonstrations against the government's austerity program, he was ousted in a bloodless coup by a group of army officers headed by Lt. Col. Sangoulé Lamizana, who became head of state. Lamizana dissolved the national assembly and temporarily prohibited political activity.
In 1970 a new constitution was approved in a national referendum; Lamizana was to remain in power until 1975, when he would be replaced by an elected president. The UDV did well in the 1970 legislative elections and Lamizana appointed Gérard Kango Ouedraogo to be prime minister. However, in 1974, the army, headed by Lamizana, again intervened in the political process, dissolving the national assembly, ousting Ouedraogo, and suspending the 1970 constitution.
During the 1960s and early 1970s, Upper Volta received a great deal of financial aid from France. The country (especially the north) was severely affected by the long-term drought that began in the late 1960s and continued into the 1970s. Upper Volta was involved in a border dispute with Mali in 1974 over land containing mineral reserves. The dispute resulted in a national strike and demands for higher wages and a return to civilian rule.
A new constitution was promulgated in 1977, and multiparty presidential and legislative elections were held in 1978; Lamizana was returned to office, but in 1980 he was overthrown in a military coup by Col. Saye Zerbo. Labor unrest characterized Zerbo's brief tenure and Maj. Jean-Baptiste Ouédraogo launched a successful coup in 1982. Ouédraogo's regime proved to be short-lived as well; he was ousted by Capt. Thomas Sankara in 1983 in a bloody coup.
Sankara cultivated ties with Libya and Ghana, adopting a policy of nonalignment with Western nations. He adopted a more liberal policy toward the opposition and increased the government's focus on economic development. In symbolic rejection of the nation's colonial past, Upper Volta became Burkina Faso in 1984; the name is a composite of local languages and is roughly translated as "the land of incorruptible men." The country's dispute with Mali over the Agache border was revived in 1985. In 1986, Sankara dissolved his cabinet and appointed civil servants to government ministries. Subsequently, he proposed the formation of a single political party.
Sankara and other officials were assassinated in 1987, and Capt. Blaise Compaoré seized control. Compaoré, unlike his predecessor, began to attract foreign investment and expanded the private sector. In 1991 a new constitution was approved, and in the subsequent presidential election Campaoré (the only candidate) was elected. In 1992 the country held its first multiparty parliamentary elections since 1978; Compaoré's party won over two thirds of the seats amid widespread charges of fraud. The party made even bigger gains in the 1997 elections, and Campaoré, facing weak opponents, was reelected in 1998. In May, 2002, the ruling Congress for Democracy and Progress (CDP) retained control of the national assembly, winning 57 seats. The president was again reelected in 2005, enormously outspending an opposition splintered among 12 candidates.
In Dec., 2006, several days of armed clashes between soldiers and police disrupted life in Ouagadougou; the violence began when police stopped a group of soldiers in civilian clothes and a fight broke out. Burkina's southern neighbor, meanwhile, has accused it of aiding N Ivorian rebels. The governing party increased its majority in the national assembly after the May, 2007, elections. Compaoré was reelected president in Nov., 2010; again facing weak opponents, he won by a landslide. In the first half of 2011, however, unrest in the country increased, and there were a series of protests, strikes, riots, and even army and police mutinies in the capital and other cities. The Dec., 2012, legislative elections were again a victory for Compaoré's party and its allies. In recent years relations have been strained at times with Côte d'Ivoire, which has been accused by the government of mistreating Burkinabe there.
