CHICAGO (AP) — The Rev. Jesse L. Jackson, a protege of the Rev. Martin Luther King Jr. and two-time presidential candidate who led the Civil Rights Movement for decades after the revered leader’s assassination, died Tuesday. He was 84.

As a young organizer in Chicago, Jackson was called to meet with King at the Lorraine Motel in Memphis, Tennessee, shortly before King was killed, and he publicly positioned himself thereafter as King’s successor.

Santita Jackson confirmed that her father, who had a rare neurological disorder, died at home in Chicago, surrounded by family.

Jackson led a lifetime of crusades in the United States and abroad, advocating for the poor and underrepresented on issues, including voting rights, job opportunities, education and health care. He scored diplomatic victories with world leaders, and through his Rainbow/PUSH Coalition, he channeled cries for Black pride and self-determination into corporate boardrooms, pressuring executives to make America a more open and equitable society.

And when he declared, “I am Somebody,” in a poem he often repeated, he sought to reach people of all colors. “I may be poor, but I am Somebody; I may be young; but I am Somebody; I may be on welfare, but I am Somebody,” Jackson intoned.

It was a message he took literally and personally, having risen from obscurity in the segregated South to become America’s best-known civil rights activist since King.

“Our father was a servant leader — not only to our family, but to the oppressed, the voiceless, and the overlooked around the world,” the Jackson family said in a statement posted online. “We shared him with the world, and in return, the world became part of our extended family.”

Fellow civil rights activist the Rev. Al Sharpton said his mentor “was not simply a civil rights leader; he was a movement unto himself.”

“He taught me that protest must have purpose, that faith must have feet, and that justice is not seasonal, it is daily work,” Sharpton wrote in a statement, adding that Jackson taught “trying is as important as triumph. That you do not wait for the dream to come true; you work to make it real.”

Despite profound health challenges in his final years, including the disorder that affected his ability to move and speak, Jackson continued protesting against racial injustice into the era of Black Lives Matter. In 2024, he appeared at the Democratic National Convention in Chicago and at a City Council meeting to show support for a resolution backing a ceasefire in the Israel-Hamas war.

“Even if we win,” he told marchers in Minneapolis before the officer whose knee kept George Floyd from breathing was convicted of murder, “it’s relief, not victory. They’re still killing our people. Stop the violence, save the children. Keep hope alive.”

Jackson’s voice, infused with the stirring cadences and powerful insistence of the black church, demanded attention. On the campaign trail and elsewhere, he used rhyming and slogans such as “Hope not dope” and “If my mind can conceive it and my heart can believe it, then I can achieve it,” to deliver his messages.

Jackson had his share of critics, both within and outside of the black community. Some considered him a grandstander, too eager to seek the spotlight. Looking back on his life and legacy, Jackson told The Associated Press in 2011 that he felt blessed to be able to continue the service of other leaders before him and to lay a foundation for those to come.

“A part of our life’s work was to tear down walls and build bridges, and in a half century of work, we’ve basically torn down walls,” Jackson said. “Sometimes when you tear down walls, you’re scarred by falling debris, but your mission is to open up holes so others behind you can run through.”

In his final months, as he received 24-hour care, he communicated with family and visitors by holding their hands and squeezing.

“I get very emotional knowing that these speeches belong to the ages now,” his son, Jesse Jackson Jr., told the AP in October.

Jesse Louis Jackson was born Oct. 8, 1941, in Greenville, South Carolina, the son of high school student Helen Burns and Noah Louis Robinson, a married man who lived next door. Jackson was later adopted by Charles Henry Jackson, who married his mother.

Jackson was a star quarterback on the football team at Sterling High School in Greenville, and he accepted a football scholarship from the University of Illinois. But after reportedly being told that black people couldn’t play quarterback, he transferred to North Carolina A&T in Greensboro, where he became the first-string quarterback, an honor student in sociology and economics, and student body president.

Arriving on the historically black campus in 1960 just months after students there launched sit-ins at a whites-only lunch counter, Jackson immersed himself in the blossoming Civil Rights Movement.

By 1965, he joined the voting rights march King led from Selma to Montgomery, Alabama. King dispatched him to Chicago to launch Operation Breadbasket, a Southern Christian Leadership Conference effort to pressure companies to hire Black workers.

Jackson called his time with King “a phenomenal four years of work.”

Jackson was with King on April 4, 1968, when the civil rights leader was slain. Jackson’s account of the assassination was that King died in his arms.

Sharpton said he “always wondered how much trauma that must have been” for Jackson to witness King’s death. “He never would talk about it too much, but it drove him,” Sharpton said Tuesday. “He said, ‘We’ve got to keep Dr. King’s legacy alive.'”

With his flair for the dramatic, Jackson wore a turtleneck he said was soaked with King’s blood for two days, including at a King memorial service held by the Chicago City Council, where he said: “I come here with a heavy heart because on my chest is the stain of blood from Dr. King’s head.”
