Jimmy Cliff, one of the most prominent and beloved proponents of reggae music, has died at the age of 81.

A star since the 1960s, he helped to bring the sound of Jamaica to a global audience through hits such as Wonderful World, Beautiful People and You Can Get It If You Really Want.

His lead role as a gun-toting rebel in the 1972 crime drama The Harder They Come is a cornerstone of Jamaican cinema, and was attributed as the movie that brought reggae to America.

Cliff's wife, Latifa Chambers, announced his death via a statement on Instagram.

"It's with profound sadness that I share that my husband, Jimmy Cliff, has crossed over due to a seizure followed by pneumonia," she wrote.

"I am thankful for his family, friends, fellow artists and coworkers who have shared his journey with him.

"To all his fans around the world, please know that your support was his strength throughout his whole career.

"Jimmy, my darling, may you rest in peace. I will follow your wishes."

Her message was also signed by their children, Lilty and Aken.

Born James Chambers in 1944, Cliff grew up as the eighth of nine children in abject poverty in the parish of St. James, Jamaica.

Blessed with a sweet, mellifluous voice, he began singing at his local church at the age of six.

By the time he was 14, he'd moved to Kingston and adopted the surname Cliff to express the heights he intended on reaching.

He recorded several singles before topping the Jamaican charts with his own composition, Hurricane Hattie.

In 1965, he relocated to London to work with Island Records - later the home of Bob Marley - but the label's attempts to make his sound palatable to rock audiences weren't entirely successful at first.

He eventually struck gold with the 1969 single Wonderful World, Beautiful People - an upbeat, feelgood anthem; and the more politically-charged Vietnam, which Bob Dylan called "the best protest song ever written".

Its lyric tells the story of a young soldier who writes from the war, promising his mother he'll be home soon; only for her to receive a telegram the next day, informing her of his death.

Cliff reflected on the song in 1986, telling reggae archivist Roger Steffens: "The essence of my music is struggle. What gives it the icing is the hope of love."

The Harder They Come had to be subtitled in the US because of the character's thick Jamaican patois

Cliff became an international star with The Harder They Come, expressly written for the movie of the same name, in which he played Ivan Martin, a young man trying to break into Jamaica's corrupt music industry.

"The film opened the door for Jamaica," Cliff recalled. "It said, 'This is where this music comes from.'"

Cliff contributed four songs to the soundtrack, including the gospel hymn Many Rivers To Cross, which reflected his early days as a struggling artist in the UK.

"I was still in my teens," he later recalled. "I came full of vigour: I'm going to make it, I'm going to be up there with the Beatles and the Stones."

"And it wasn't really going like that, I was touring clubs, not breaking through. I was struggling, with work, life, my identity. I couldn't find my place. Frustration fuelled the song."

Instead, the film and its soundtrack won him international acclaim. Rolling Stone magazine even named it one of their top 500 albums of all time.

During the 1980s, he collaborated with the Rolling Stones on their Dirty Work album, and he returned to the US charts in 1993 with his cover of I Can See Clearly Now, from the soundtrack for Cool Runnings, which followed the escapades of Jamaica's bobsled team.

His other recordings included the Grammy Award-winning albums Cliff Hanger (1985) and Rebirth (2012), a nostalgic return to form.

Cliff entered the Rock and Roll Hall of Fame in 2010, calling it "a great thrill and an honour".

Inducting him, Fugees star Wyclef Jean said he'd been inspired by Cliff's success as a young boy growing up in Haiti.

"When we saw Jimmy Cliff, we saw ourselves," he said.

Cliff continued to tour late into his life, playing Glastonbury's legends slot in 2003; and winning over a new generation of fans at the 2010 Coachella Festival.

His contributions to Jamaican music and culture were recognised in October 2003 when he was awarded the country's prestigious Order of Merit.

But the singer said his connection to fans was more important than any of the other honours bestowed upon him.

Speaking to US radio station NPR in 2012, he reflected: "When someone comes up to me and says, 'I was a dropout in school and I heard your song You Can Get It If You Really Want, and that song made me go back to school, and now I am a teacher and I use your song with my students' - that, for me, is a big success."
