AFRICANGLOBE - In 1987, Blaise Compaoré overthrew Thomas Sankara and took over the presidency. 27 years later, Thomas Sankara's ghost may be coming back to return the favour. 30 years ago, on 4 August, 1984, the former French colony of the Upper Volta was re-baptised as 'Burkina Faso' amidst a revolutionary process that proved to be one of the most inspiring, yet ultimately tragic, episodes of modern African history.
