FILE - In this Feb. 28, 1966 file photo, students of the Ghanian trades union congress heap communist and Pro-Kwame Nkrumah magazines and newspapers onto a bonfire outside Congress House in Accra, Ghana in the wake of the overthrow of Nkrumah's government during the week of Feb. 20, 1966. Until fairly recently, coups were a hallmark of African governance. But since the 1990s the continent has struggled to embrace democracy, and Ghana has been a trailblazer. (AP Photo)
