Miguel Calhoun of the Black Justice Party.
Miguel Calhoun was a former slave in Durango who led the southern wing of the Black Justice Party during the Rainbow War insurrection from 1944 to 1948, then succeeding to the leadership of the organization after the death of Philip Harrison. Calhoun carried out terrorist attacks on the Anglo, Hispano, and Mexicano populations of Durango and Chiapas. This brought him into conflict with the Mexicano revolutionary Armondo Santa Cruz, the leader of Causa de Justicia, and his followers fought several battles with those of Santa Cruz.
In his book Justice Now!, Mitchell Armitage wrote that, "Santa Cruz and Calhoun together might have toppled the Silva government, taken Mexico out of the war, and instituted a new era of social justice in the U.S.M. But each man hated the other more than they did the Anglos and Hispanos, and so the viper of racial bigotry destroyed Mexico's best chance for a true revolution."
