The body of John Lewis will cross the Edmund Pettus Bridge one last time on Sunday, in what organizers are calling "The Final Crossing," part of a multi-day celebration of the life of the civil rights icon.

Watch live here beginning at 11:00 a.m. ET:

In March of 1965, a 25-year-old Lewis and hundreds of other civil rights advocates planned to march from Selma to Montgomery to draw attention to the need for voting rights in the state, which was infamous for denying African Americans the right to vote.

"We're marching today to dramatize to the nation, dramatize to the world the hundreds and thousands of Negro citizens of Alabama that are denied the right to vote," Lewis said. "We intend to march to Montgomery to present said grievance to Governor George C. Wallace."

But as Lewis led the group across the Edmund Pettus Bridge in Selma, he saw a line of white Alabama State Troopers blocking their path. The commander's orders were clear: Gov. George Wallace had proclaimed the march illegal.

"You're ordered to disperse," said Maj. John Cloud of the Alabama Department of Public Safety. "Go home or go to your church. This march will not continue."

Lewis and his group did not disperse.

"Troopers, here, advance toward the group," Cloud said.

The line of troopers walked forward, billy clubs out. They knocked Lewis to the ground, and struck him on his head. He tried to get up; they hit him again with the billy club. His skull was fractured.

"I thought I was going to die," Lewis told NPR in 2010. "I thought I saw death."

Lewis didn't die that day. Images from "Bloody Sunday," as it came to be known, were broadcast across the nation. The ensuing coverage helped lead to the passage of the Voting Rights Act of 1965, which prohibits racial discrimination in voting. And it catapulted Lewis onto the national stage and a more than 30-year career in Congress as a representative from Georgia.

On Saturday, Lewis was remembered at a memorial service in his hometown. Last night he was honored at a service in Selma, where his body lied in repose as mourners paid their respects. After today's passage across the bridge, Lewis will be received at the Alabama State Capitol.

On Monday, Lewis's body will lie in state at the U.S. Capitol in Washington, D.C. After an invitation-only arrival ceremony Monday afternoon, members of the public will be able to pay their respects in a masked and socially distant line on the Capitol's East Plaza.
