Selma to Montgomery marches (1965)
Civil rights marchers crossing the Edmund Pettus Bridge in Selma, Alabama, were beaten by state troopers on March 7, 1965. The images helped build support for the Voting Rights Act, which Congress passed that August.
Federal officials moved to protect marchers and Congress took up voting rights legislation.
The Voting Rights Act gave the federal government tools to challenge state and local barriers to voting.
The Selma events led to federal protections against the kind of polling-place intimidation the Las Vegas order addresses.
