The Voting Rights Act of 1965

After Martin Luther King's March on Selma in February of 1965, President Lyndon Johnson kind of finally gets on board and calls for legislation later that same year. Section 4B of the Voting Rights Act contains a formula that determines which jurisdictions this applies to. The formula covers jurisdictions that as of initially was November 1964 and then November 1968. And then 1972 maintained a prohibited test or device as a condition of registering to vote or voting.
