George Floyd had been dead only hours before the movement began. Driven by a terrifying video and word-of-mouth, people flooded the South Minneapolis intersection shortly after his May 25, 2020, death, demanding an end to police violence against Black Americans.

The moment of collective grief and anger swiftly gave way to a yearlong, nationwide deliberation on what it means to be Black in America.

First came protests, growing every day, until they turned into the largest mass protest movement in U.S. history. Nearly 170 Confederate symbols were renamed or removed from public spaces. The Black Lives Matter slogan was claimed by a nation grappling with Floyd’s death.
