December 1965: Lowndes County Freedom Organization

Black voters in Lowndes County, Alabama, using a provision in state law, form an independent political party: the Lowndes County Freedom Organization (also known as the Black Panther Party). The party fields a slate of 7 candidates for county offices in the November 1966 general election.
Until 1965, not one black person was registered to vote in Lowndes, though blacks made up 80% of the county's population. By October 1965 -- following a series of voter registration drives and the enactment of the Voting Rights Act in August -- nearly half the black population had registered to vote.

-- Note: The LCFO based its symbol on the Panther mascot of Clark College in Atlanta, Georgia. In turn, the Black Panther Party for Self-Defense (formed in October 1966), took its name and symbol from the LCFO.

The 1965 Voting Rights Act passed in the wake of Selma dramatically began to boost the number of black registered voters. And a unique Alabama law encouraged creation of county-level political parties. The law stipulated you had to have a symbol because of the high rate of illiteracy, recalls Kwame. Well, the Democratic Party symbol was a white rooster, the white cock party we used to call it. A panther became the new party’s symbol...almost accidentally.
Courtland [Cox] came to Atlanta and asked me to design a business card with an emblem for the party, recalls Ruth Howard Chambers. I came up with a dove. Nobody thought that worked and someone said I should look at the Clark College emblem. It was a panther and that’s where the panther came from. Somebody up there traced it on a piece of paper for me. In Lowndes County that pouncing black panther gave instant visibility to the newly-formed Lowndes County Freedom Organization as the Black Panther Party. The new party’s slogan: Power for black people.
Almost immediately, the black panther leapt out of the state. When a volunteer from Oakland, California working in Lowndes county returned home, Huey P. Newton and Bobby Seale asked for permission to use the emblem for the Black Panther Party they had decided to form.
