What type of integration was the United States famous for in the past

Desegregation was not always a battle in every community in the South. Lawrence Guyot, who later became a leader in the Student Nonviolent Coordinating Committee, grew up in Pass Christian, a city on the Mississippi Gulf Coast that was influenced by the strong labor unions in the shipyard industry and the Catholic Church. He explains how the Catholic schools were desegregated there: "The Catholic Church in 1957 or '58 made a decision that they were going to desegregate the schools. They did it this way. The announcement was we have two programs. We have excommunication and we have integration. Make your choice by Friday. Now there was violence going on in Louisiana. Nothing happened on the Gulf Coast. I learned firsthand that institutions can really have an impact on social policy."
