Thousands of black men, women, and children convened at the National Mall in Washington, D.C., for the “Justice or Else” rally to commemorate the 20th anniversary of the Million Man March on Saturday (Oct. 10). Some celebrities were in attendance including Diddy, Common, J. Cole and Snoop Dogg.

Also in attendance at the rally were rappers Jay Electronica, Jeezy, Ty Dolla $ign and Bryshere Gray who plays Hakeem on Fox's hit show Empire. Rap mogul Russell Simmons and Public Enemy founder Chuck D was also spotted in the crowd.

The event was organized by Nation of Islam leader the Honorable Minister Louis Farrakhan who called for an economic boycott of Christmas, among other things. Prior to Farrakhan's speech, several civil rights leaders appeared at the podium to demand justice for the killings of black men by the hands of police.

Melina Abdullah, a Black Lives Matter leader, urged black men and women to fight for their civil rights. "Pulling our pants up will not save us," she said. "Our college degrees cannot save us. Our middle-class status cannot save us."

Elsewhere, hundreds marched to the event chanting the chorus from Kendrick Lamar’s anti-police brutality song “Alright" from his To Pimp a Butterfly album.

The peaceful event was a reminder that there's still more work to be done in the ongoing efforts of maintaining civil rights and equal justice for African-Americans.
