Several noted public figures, including Cornell West and Chuck D., will be leading a rally and march to commemorate the 30th anniversary of the MOVE tragedy tomorrow.

On May 13, 1985, Philadelphia police under orders from city officials dropped a bomb on a home at 6221 Osage Ave. occupied by several members of the MOVE organization. Eleven people, including five children, died in the resulting fire and dozens of nearby homes were destroyed.

The rally starts at 11 a.m. at 62nd and Osage and organizers are asking participants to “walk, bike, jog or caravan” to 38th and Market where a speak-out will begin at 4 p.m. Activist Angela Davis and writer Alice Walker have prepared video messages that will be played. Speakers include West, Chuck D., hop hop artist Rebel Diaz, activist and attorney Alton Maddox and activists from the Black Lives Matter movement.

If you are unfamiliar with the MOVE or the events surrounding the bombing, here is an excellent documentary released in 2013 that pieces together news footage and interviews. Other background resources include a post on Philadelphia Magazine’s site today. Here is a look back from the Philadelphia Inquirer during the 25th anniversary.
