The Selma to Montgomery march, also known as "Bloody Sunday," was a pivotal moment in the American civil rights movement. It took place in March 1965 in Alabama and was organized to protest the denial of voting rights to African Americans. The march was led by civil rights leaders such as John Lewis, Martin Luther King Jr., and Hosea Williams.

On March 7, 1965, around 600 peaceful protesters began the march from Selma to Montgomery, the state capital. However, as they crossed the Edmund Pettus Bridge in Selma, they were met by state troopers and local law enforcement officers who brutally attacked the marchers with batons, tear gas, and horses. The violent confrontation was captured on national television and shocked the country, leading to widespread outrage and increased support for the civil rights movement.

In response to the violence, Dr. King called for clergy and civil rights supporters from across the country to join a second attempt at the march. On March 21, 1965, a successful five-day, 54-mile march from Selma to Montgomery took place, with thousands of people participating. The marchers were protected by federal troops and reached the state capitol on March 25, where Dr. King delivered his famous "How Long, Not Long" speech.

The Selma to Montgomery march played a crucial role in the passage of the Voting Rights Act of 1965, which prohibited racial discrimination in voting and was a significant victory for the civil rights movement. It remains a powerful symbol of the struggle for equality and justice in America.
