How many new segregation laws were passed from 1956?

From 1956 onwards, the United States saw a significant decline in the passage of new segregation laws, particularly due to the Civil Rights Movement and subsequent federal legislation. The Civil Rights Act of 1964 and the Voting Rights Act of 1965 aimed to dismantle legalized segregation and discrimination. While some local ordinances persisted, the era of formal segregation laws effectively ended by the late 1960s, resulting in very few new laws being enacted after 1956.
