For me and many others, Marcus Garvey qualifies as the greatest Black man of the past hundred years. Of course, there are many, many others. There is Kwame Nkrumah and Haile Selassie I and Patrice Lumumba and Nelson Mandela from Africa. And Dr. B.R. Ambedkar, the great hero of the Dalits of India, ranks high as well. But for me, Garvey is tops.
