Free food seemed relatively innocuous, but not to FBI head J. Edgar Hoover, who loathed the Black Panther Party and declared war against them in 1969. He called the program “potentially the greatest threat to efforts by authorities to neutralize the BPP and destroy what it stands for,” and gave carte blanche to law enforcement to destroy it.

The results were swift and devastating. FBI agents went door-to-door in cities like Richmond, Virginia, telling parents that BPP members would teach their children racism. In San Francisco, writes historian Franziska Meister, parents were told the food was infected with venereal disease; sites in Oakland and Baltimore were raided by officers who harassed BPP members in front of terrified children, and participating children were photographed by Chicago police.

“The night before [the first breakfast program in Chicago] was supposed to open,” a female Panther told historian Nik Heynan, “the Chicago police broke into the church and mashed up all the food and urinated on it.”

Ultimately, these and other efforts to destroy the Black Panthers broke up the program. In the end, though, the public visibility of the Panthers’ breakfast programs put pressure on political leaders to feed children before school. The result of thousands of American children becoming accustomed to free breakfast, former party member Norma Amour Mtume told Eater, was the government expanded its own school food programs.
