President Lyndon B. Johnston signed the Civil Rights Act of 1964, making it illegal to discriminate based on race, religion, sex, national origin, or color of skin. This landmark legislation outlawed government discrimination and the unequal application of voting qualifications by race and also prohibited segregation and other forms of discrimination in most businesses that were open to the public.
