This historical account of Colorado's progress in human relations addresses itself to two questions: (1) What was the general attitude toward human relations problems on the part of those who settled and developed Colorado? (2) What changes have been brought about over a century? The first of five parts defines the concept of human relations and its meaning to Coloradoans. The second is concerned with the struggles of principal minorities. The third traces progress through formal programs--the Anti-Defamation League, Denver Urban League, and other groups. The fourth records conflicts over housing, education, and status of Hispanos and Afro-Americans. The fifth part summarizes and evaluates the entire presentation, which is intended as a resource and orientation work for those involved in intergroup activities, students, and the interested public.
