The Warren Court was the period in the history of the Supreme Court of the United States from 1953 to 1969 when Earl Warren served as the chief justice. The Warren Court is often considered the most liberal court in U.S. history.

Earl Warren was an American lawyer, politician, and jurist who served as the 30th governor of California from 1943 to 1953 and as the 14th Chief Justice of the United States from 1953 to 1969. The Warren Court presided over a major shift in American constitutional jurisprudence, which has been recognized by many as a "Constitutional Revolution" in the liberal direction, with Warren writing the majority opinions in landmark cases such as Brown v. Board of Education (1954), Reynolds v. Sims (1964), Miranda v. Arizona (1966), and Loving v. Virginia (1967). Warren also led the Warren Commission, a presidential commission that investigated the 1963 assassination of President John F. Kennedy. He served as Governor of California from 1943 to 1953, and is the last chief justice to have served in an elected office before nomination to the Supreme Court. Warren is generally considered to be one of the most influential Supreme Court justices and political leaders in the history of the United States.
