A national monument dedicated to Emmett Till and his mother, Mamie Till-Mobley, will finally be a reality after years of efforts to prompt federal recognition of the teenager whose brutal 1955 killing in Mississippi helped spark the Civil Rights Movement that would follow.

President Joe Biden announced the decision Tuesday, which would have been Till’s 82nd birthday.

“At a time when there are those who seek to ban books, bury history, we’re making it clear — crystal, crystal clear — (that) while darkness and denialism can hide much, they erase nothing,” Biden said at a ceremony held Tuesday at Washington’s Eisenhower Executive Office Building announcing the proclamation. “…. Only with truth comes healing, justice, repair, and another step forward toward forming a more perfect union.  We got a hell of a long way to go.”

In a release accompanying the announcement, the Biden administration said the designation of a national monument honoring Till builds on its work to advance civil rights and racial justice, including Biden’s signing of the Emmett Till Anti-Lynching Act, codifying lynching as a federal hate crime.

The Emmett Till and Mamie Till-Mobley National Monument will comprise 5.7 acres across several historic sites in Mississippi and Illinois, tapping and encouraging partnerships between the U.S. Department of the Interior, the National Park Service and local communities and organizations to preserve the memory of one of America’s most infamous hate crimes.

“The National Park Service cannot bring the Till family the justice they were so cruelly denied in 1955,” said Theresa Pierno, president and CEO of the National Parks Conservation Association. “But with this new national park site, our leaders are bringing this story back into the light so that we may all continue to learn and grow from it, just as we have at Birmingham, Stonewall, and other national monuments.”

A teen’s brutal killing shocks the nation

Till was a 14-year-old Chicago teen when he traveled to Mississippi’s Tallahatchie County to stay with relatives in August 1955. A few days later, he and his cousins stopped to get refreshments at Bryant’s Grocery & Meat Market in the rural community of Money, about 110 miles north of Jackson.
