Thousands march from the Lincoln Memorial to protest the Iraq War at the Pentagon

On March 17, 2007, thousands of demonstrators marched from the Lincoln Memorial in Washington, D.C., to the Pentagon's north parking lot to protest the Iraq War. Estimates of participation ranged from approximately 4,000 to 15,000 people, reflecting differences among contemporary accounts. The demonstration took place during continuing public debate over United States military operations in Iraq, which had begun in March 2003. By choosing the Pentagon as their destination, participants directed their protest toward the headquarters responsible for administering American military operations. The march followed earlier antiwar demonstrations at the same location during the Vietnam War, including the prominent October 1967 March on the Pentagon. The event demonstrated the Pentagon's continuing role as a focal point for political activism concerning American military involvement overseas.
