Armondo Santa Cruz was a Mexicano politician in Durango who led the revolutionary Mexicano group Causa de Justicia in the Rainbow War insurrection during and after the Global War. At its height, Causa de Justicia had 20,000 members, and as its leader Santa Cruz made speeches demanding land for poor Mexicano peasants. Causa de Justicia carried out bombing attacks in Anglo and Hispano areas of Durango. Santa Cruz was strongly anti-black, and his followers fought several battles with the followers of Miguel Calhoun of the Black Justice Party.
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."
