In 1968, Eldridge Cleaver became the Peace and Freedom Party's first presidential candidate. He was nominated for president at the Peace and Freedom Party National Convention in Ann Arbor, Michigan. He was also nominated for president at the State Convention in Sacramento, California. The Secretary of State refused to place Cleaver's name on the ballot in California because he did not meet the legal age requirement to hold the office if he were to be elected.
A collection of his essays, first published in Ramparts magazine, was published in book form by McGraw-Hill in 1968 and titled Soul on Ice.
Eldridge Cleaver died on May 1, 1998.
