Supporters of the federal Voting Rights Act are planning a series of events across Alabama to highlight the importance of the law.
Activities are being held in Selma, Huntsville, Montgomery, Birmingham and other cities on Tuesday in conjunction with what organizers are calling "National Voting Rights Day."
The Supreme Court recently overturned a key section of the law, and activists are trying to draw attention to their claims that the act is still needed.
Candlelight vigils and other events are being scheduled. In Selma, participants will walk across the Edmund Pettus Bridge to recommit themselves to civil rights.
Similar events are being planned in other states.
Tuesday marks the 48th anniversary of President Lyndon Johnson signing the bill into law in 1965.
