2 January 1964
On 2 January 1964, Kwame Nkrumah, first Ghanaian President survived fifth assassination attempt. Shortly thereafter, he declared Ghana a one party state. During the same year Nkrumah forced a constitutional amendment allowing him to dismiss any judge. Ghanaians were not happy with the amendments and other changes that he introduced. In August 1962, Nkrumah narrowly escaped death when he was bombed in Khungulu village. Following the 1962 attempt to eliminate him, three of his close allies, Foreign Minister Ako Adjei, Information Minister Tawia Adamafio, and party boss H. H. Cofie-Crabbe were jailed. Just months after he was re-elected, on 24 February 1966, he was deposed as President.
