Since independence from
Portugal in 1974, Guinea-Bissau has experienced considerable political
and military upheaval. In 1980, a military coup established
authoritarian dictator Joao Bernardo 'Nino' Vieira as president.
Despite setting a path to a market economy and multiparty system,
Vieira's regime was characterized by the suppression of political
opposition and the purging of political rivals. Several coup attempts
through the 1980s and early 1990s failed to unseat him. In 1994 Vieira
was elected president in the country's first free elections. A military
mutiny and resulting civil war in 1998 eventually led to Vieira's
ouster in May 1999. In February 2000, a transitional government turned
over power to opposition leader Kumba Yala, after he was elected
president in transparent polling. In September 2003, after only three
years in office, Yala was ousted by the military in a bloodless coup,
and businessman Henrique Rosa was sworn in as interim president. In
2005, former President Vieira was re-elected president pledging to
pursue economic development and national reconciliation.
Portuguese
is the official language; Crioulo and various African languages are
also spoken.
