Angola's former president Jose Eduardo dos Santos, who ruled Africa's second-biggest oil producer for nearly four decades, died on Friday, the presidency said.
The 79-year-old died at the Teknon clinic in Barcelona, Spain, where he was being treated following a prolonged illness, according to the statement.
His successor, President Joao Lourenco, declared five days of national mourning and described dos Santos as a "unique figure of the Angolan homeland."
Dos Santos' daughter Tchizé dos Santos said in an Instagram post that "fathers never die because they are the truest love that children know in all their lives. They live forever within us".
