Ghanaian President Kwame Nkrumah, who led the "movement of global Blackness" in the late 1950s.

Howard K. French, professor, journalist and bestselling author talks about his new book "Second Emancipation" with Host Llewellyn King and Co-host Adam Clayton Powell III. The book is the second installment in a trilogy, which refers to the brief period beginning in 1957 when a slew of African colonies became countries. The liberation, French writes in his book, was at the center of a "movement of blackness," led by Ghana's charismatic first president, Kwame Nkrumah.
