Guinea-Bissau country profile
West Africa's Guinea-Bissau was part of the Portuguese Empire for centuries.
Once hailed as a potential model for African development, the country is now one of the poorest in the world.
The vital cashew nut crop provides a modest living for most of Guinea-Bissau's farmers, and is the main source of foreign exchange.
But today the nation has a massive foreign debt and an economy that relies heavily on foreign aid. It has become transhipment point for Latin American drugs.
At the end of the 1990s the country experienced a conflict which drew in Guinea, Nigeria, Senegal, and France and ended with the president going into exile.
President: Umaro Sissoco Embaló
Mr Embaló won the December 2019 presidential election, but faced a last-minute stand-off with parliament before taking office in February.
This reflected the continuing instability of state institutions in a country that has seen nine coups or attempted coups since 1980, and the resistance of the long-governing PAIGC party to the victory of an opposition candidate.A former prime minister, Mr Embaló is the first president to be elected without the backing of the PAIGC.
His predecessor, Jose Mario Vaz, was the first elected leader since the army mutinied in 2012 and plunged the country - already plagued by corruption and cocaine trafficking - into chaos, and the first to complete his term without being overthrown.
The constitution provides for press freedom and there is some media diversity, says US NGO Freedom House. But it says journalists face harassment.
Private radio stations operate alongside the state broadcaster. A government newspaper publishes alongside non-state titles.
