Voting Rights Act (1965)
President Lyndon Johnson signed the Voting Rights Act after marches in Selma. It required federal approval for election changes in states with histories of discrimination, and Black voter registration rose across the South.
The law faced court challenges but survived for decades.
The 2013 Shelby County decision and the 2026 ruling narrowed federal oversight.
The 2026 midterms tested whether Black turnout could offset weaker federal oversight.
