King's struggle continued throughout the 1960s. Often, it seemed as though the pattern of progress was two steps forward and one step back. On March 7, 1965, a civil rights march, planned from Selma to Alabama's capital in Montgomery, turned violent as police with nightsticks and tear gas met the demonstrators as they tried to cross the Edmond Pettus Bridge. King was not in the march, however the attack was televised showing horrifying images of marchers being bloodied and severely injured. Seventeen demonstrators were hospitalized leading to the naming the event "Bloody Sunday." A second march was cancelled due to a restraining order to prevent the march from taking place. A third march was planned and this time King made sure he was on it. Not wanting to alienate southern judges by violating the restraining order, a different tact was taken. On March 9, 1965, a procession ofThe rising tide of civil rights agitation produced a strong effect on public opinion. Many people in cities not experiencing racial tension began to question the nation's Jim Crow laws and the near century second class treatment of African-American citizens. This resulted in the passage of the Civil Rights Act of 1964 authorizing the federal government to enforce desegregation of public accommodations and outlawing discrimination in publicly owned facilities. This also led to Martin Luther King receiving the Nobel Peace Prize for 1964.
