She also performed Lift Every Voice and Sing, which is known as the national black anthem, at the festival and donated US$100,000 ($146,000) to four black universities shortly after her performance.
Jay-Z received the President's Award for the rapper's public service achievements. He was recognised for his efforts through his Shawn Carter Foundation and serving as co-founder of the REFORM Alliance.
The rapper executive produced the documentaries Rest in Power: The Trayvon Martin Story and Time: The Kalief Browder Story, along with an animated documentary short called The War on Drugs is an Epic Fail. That documentary highlighted the unfavourable treatment of black and Latino people when it comes to drug-related crimes.
Jay-Z quoted Abraham Lincoln after he accepted his award and dedicated his trophy to his 93-year-old grandmother Hattie White.
"It's not the amount of years in your life. It's the amount of life in your years," he said. "That quote embodies my beautiful grandmother."
Black Panther was awarded for best motion picture. The Marvel blockbuster hit beat out BlacKkKlansman, Crazy Rich Asians, If Beale Street Could Talk and The Hate U Give.
The movie won in several other categories, including best actor in a motion picture (Chadwick Boseman), supporting actor in a motion picture (Michael B. Jordan) and directing in a motion picture (Ryan Coogler).
Jussie Smollett, who lost to Grey's Anatomy star Jessie Williams in the outstanding supporting actor in a drama series category, did not attend the awards.
It had been a tumultuous week for the Empire star after a felony case against him was dropped in Chicago. The handling of the case, which accused Smollett of falsely reporting to police that he was assaulted in Chicago two months ago, has drawn widespread condemnation.
Actor-comedian Chris Rock took verbal jabs at Smollett before he announced that ABC series Black-ish won for outstanding comedy series.
"They said no Jussie Smollett jokes," Rock said. "Yeah, I know, but what a waste of light skin. Do you know what I could do with that light skin? That curly hair, my career would be out of here ... What the hell was he thinking?"
