"Following Portugal's April 1974 Carnation Revolution..."

"... , it granted independence to Guinea-Bissau on 10 September 1974."

Luís Cabral, Amílcar Cabral's half-brother, became President of Guinea-Bissau.   Following independence local soldiers that fought along with the Portuguese Army against the PAIGC guerrillas were slaughtered by the thousands. A small number escaped to Portugal or to other African nations. The most famous massacre occurred in Bissorã. In 1980 PAIGC admitted in its newspaper "Nó Pintcha"...  that many were executed and buried in unmarked collective graves in the woods of Cumerá, Portogole and Mansabá.

Today's "History of" country is Guinea-Bissau.
