Many of the Black Panther Party leadership had become entangled in criminal trials or were serving long prison sentences. Some had been killed. The remaining BPP leaders could not agree on how to overcome these issues. A serious split occurred within the party. Panther leaders Huey Newton and David Hilliard favored a focus on community service coupled with self-defense. Others such as Eldridge Cleaver, the minister of information, embraced a more militant strategy.
Cleaver deepened the schism in the party when he publicly criticized the party for adopting a "reformist" rather than "revolutionary" agenda. He openly called for Hilliard's removal. As a result Cleaver was expelled from the BPP's Central Committee. However, Cleaver went on to lead the Black Liberation Army, which had previously existed as an underground paramilitary wing of the party.
In 1972, Bobby Seale was released from prison following the Alex Rackley murder trial. He ran for the office of mayor of Oakland, and paced a respectable second in the election. His relations with Newton became strained and in 1974 they argued about a proposed movie to be made about the Black Panther Party. Newton allegedly had Seale beaten severely, and Seale went into hiding for a year. Seale would later deny the incident, but he ended his association with the Black Panther Party.
In August of 1974, Huey Newton shot and killed 17-year-old prostitute Kathleen Smith for calling him "Baby," a moniker he hated. He also pistol-whipped his tailor, Preston Callins, for making the same mistake. Arrested and charged with the murder and the assault, he managed to post $80,000 bond and flee to Cuba with a girlfriend. He remained there until 1977.
These internal political disputes and the costs of so many legal battles were decimating the BPP. Before he jumped bail in 1974, Huey Newton appointed Elaine Brown as the first female BPP chairwoman. Under Brown, the party became a significant force in local politics. Several BPP candidates or BPP-backed candidates, made runs for various offices, culminating in the election of Lionel Wilson as the first black mayor of Oakland.
