Civil Rights Act
The Civil Rights Act of 1957 was passed in order to make sure that all

guaranteeing civil rights to all Americans. In addition, it established the Commission on Civil Rights, a federal oversight committee that examined opinions of the public and state laws regarding civil rights.

Nowhere are the interests of other people mentioned.
I believe it was guerrilla warfare.
