The Civil Rights Era in America spanned decades and witnessed countless moments—some triumphant, others tragic—that helped shape both the movement and the nation. Among the era's earliest signal events, and one whose effect is felt to this day, is the landmark Brown v. Board of Education Supreme Court decision of 1954, outlawing segregation in public schools. Pictured: Nathaniel Steward, 17, recites a lesson in May, 1954, at the Saint-Dominique school in Washington, DC, where, for the first time in the U.S., Brown v. Board of Education is applied.
