A more thorough explanation:

The United States Supreme Court, also known as the Supreme Court of the United States, is the highest court in the federal system. Its members are appointed by the President and approved by the Senate. The Court was established in 1789 by Article III of the U.S. Constitution, which gives the Court the power to interpret the law and make decisions on important legal issues.

For example, in the landmark case of Brown v. Board of Education, the Supreme Court ruled that segregation in public schools was unconstitutional. This decision helped to end racial segregation in schools and was a major victory for the civil rights movement.

The Supreme Court is often called upon to interpret the Constitution and decide whether laws or government actions are constitutional. Its decisions have a major impact on American society and can shape the course of history.
