Viriato Clemente da Cruz
The MPLA was in not in Angola at this time, but was first in Conakry (the capital of Guinea) and then later in Leopoldville, Congo (now Kinshasa the capital of the DRC). Viriato da Cruz became secretary-general of the MPLA. After some time he and others, did not agree with some people in the group and this led to fighting in the streets of Leopoldville.
