of Education, which rejected the doctrine of "separate but equal". But, in 1956, under the policy of "massive resistance" led by the influential segregationist Senator Harry F. Byrd and his Byrd Organization, the Commonwealth prohibited desegregated local schools from receiving state or private funding as part of the Stanley Plan. After schools in many districts began closing in September 1958, state and district courts ruled the plan unconstitutional, and on February 2, 1959, the first Black students integrated schools in Arlington and Norfolk, where they were known as the Norfolk 17. Prince Edward County still refused to integrate, and closed their county school system in June 1959. The Supreme Court ordered the county's public schools to be, like others in the state, open and integrated in May 1964, which they finally did that September. The civil rights movement gained national support during the 1960s. Federal passage of the Civil Rights Act in June 1964 and Voting Rights Act in August 1965, and their later enforcement, helped end racial segregation in Virginia and overturn Jim Crow era state laws. In June 1967, the Supreme Court also struck down the state's ban on interracial marriage with Loving v. Virginia. In 1968, Governor Mills Godwin called a commission to rewrite the state constitution. The new constitution, which banned discrimination and removed articles which now violated federal law, passed in a referendum with 71.8% support and went into effect in June 1971. In 1977, Black members became the majority of Richmond's city council; in 1989, Douglas Wilder became the first African American elected as governor in the United States; and in 1992, Bobby Scott became the first Black congressman from Virginia since 1888. The expansion of federal government offices into Northern Virginia's suburbs during the Cold War boosted the region's population and economy. The Central Intelligence Agency outgrew their offices in Foggy Bottom during the Korean War, and moved to Langley in 1961, in part due to a decision by the National Security Council that the agency relocate outside the District of Columbia. The agency was involved in various Cold War events, and its headquarters was a target of Soviet espionage activities. The Pentagon, built in Arlington during World War II as the headquarters of the Department of Defense, was one of the targets of the September 11, 2001 attacks; 189 people died at the site when a jet passenger plane was flown into
