MONTGOMERY, Ala. (AP) — The U.S. is set to mark Martin Luther King Jr. Day, the federal holiday set aside to honor the life of the civil rights icon. But in Alabama and Mississippi, Monday is also Robert E. Lee Day in honor of the Confederate general.

Every year we honor the legacy of Martin Luther King Jr. in January. Here's everything you need to know about the holiday.

A MLK Jr. Walk on Monday will provide an opportunity for reflection from the Heartland Conservation Alliance and KC Parks. It will begin at 9 a.m. at MLK Jr. Square Park at Woodland Avenue and Dr. Martin Luther King Jr. Boulevard in Kansas City, and end at the Bruce R. Watkins Cultural Heritage Center, 3700 Dr. Martin Luther King Jr. Blvd.

Events honoring Martin Luther King Jr.’s legacy and advocating for his vision of a just, nonviolent society will occur the same day as Donald Trump's second presidential inauguration.

"I just want to live in hope that some of the ideals of the late Dr. King might flow over into this new administration," said one advocate.

Activists and organizations are holding rallies leading up to MLK Day and convening meetings with state lawmakers to strategize on how to safeguard policies and avoid funding cuts to social service programs that largely support Black and Latino communities.
