Tucson Council for Civic Unity (TCCU) was dedicated "to foster and promote better understanding and relations among people of various racial, religious, social and national backgrounds in Arizona and to promote better conditions among all groups with respect to education, housing, employment, recreation, health and other community problems." It was affiliated with the Arizona Council for Civic Unity and  The Greater Phoenix Council for Civic Unity.

ACCU's founder was Dr. Fred G. Holmes, whose interest in initiating this agency was triggered by President Truman's Commission on Civil Rights' report of 1946, To Secure these Rights. During 1946-1947, Holmes worked with Louis Wirth and Louis E. Hosch of the American Council for Race Relations in Chicago on planning the Arizona Council for Civic Unity. Many well-known Tucsonans were involved with TCCU over the years, including Morris and Stewart Udall, Mr. and Mrs. Morgan Maxwell, Maria Urquides, Rabbi Bilgray, Dorothy Barber, Laura Banks, Thomas Bahti, Harry Gin and Sam Goddard.

The Council contributed to several achievements including the desegregation of Tucson public schools, 1948-1951, and repeal of school segregation laws in Arizona; the passage of the Equal Employment Opportunity bill, the creation of the Human Relations Commission, and in many daily local battles against racial and religious discrimination. TCCU's longest struggle was for the passage of the Public Accommodations legislation in the Arizona State Legislature.
