What was one effect of the Civil Rights Movement?

The effect of the Civil Rights Movement that is most significant is the legal rights gained for African Americans. This movement, which took place primarily during the 1950s and 1960s, aimed to end racial segregation and discrimination against African Americans and to secure equal rights under the law. Key legal milestones were achieved during this time, such as the landmark Civil Rights Act of 1964 and the Voting Rights Act of 1965, which prohibited discrimination based on race in various aspects of life, including jobs and voting. These laws played a crucial role in dismantling institutional racism and provided a legal framework for individuals to challenge unfair treatment based on race.

The other options do not directly relate to the objectives or outcomes of the Civil Rights Movement. The end of World War II is unrelated, as it pertains to global conflict rather than civil rights issues. The establishment of the U.S. Supreme Court occurred much earlier in American history and does not relate to the changes initiated by the Civil Rights Movement. Lastly, the creation of Social Security was a part of FDR's New Deal initiatives in the 1930s and not connected to the civil rights efforts aimed at addressing racial injustices in the mid-20th century.
