From global leaders and pop stars to top athletes, the world paused to remember boxing legend Muhammad Ali, who dazzled with his lightning-fast jabs, his equally quick wit and unwavering principles.

The famed boxer and icon died Friday at the age of 74, after spending 32 years fighting Parkinson’s disease. His name trended all over social media with hashtags such as the Greatest of All Time or #GOAT for short, and Rest in Power.

“To the African-American community, he was a black man who faced overwhelming bigotry the way he faced every opponent in the ring: fearlessly,” wrote NBA legend Kareem Abdul-Jabbar on Facebook.

Tributes came from his once-fiercest foes in the ring.

George Foreman, the two-time heavyweight champion who lost to Ali in the 1974 Rumble in the Jungle, mourned the man he called “the greatest piece.”

Admirers shared his amazing skill in the ring — how he appeared to bob and weave without effort, how his feet moved swiftly in a cartoonish blur.

Videos captured how precisely and quickly Ali moved, artfully dodging dozens of blows in a matter of seconds.

His speed and athleticism seemed so other worldly that even DC Comics had to show their appreciation of “a true superhero.”

Fans remembered him beyond his athletic skills, including his stand against the Vietnam War draft — even when such a position was unpopular. That steadfastness won him respect, boxing promoter Don King told CNN.

“People who didn’t like him had to respect him,” he said.

To African-Americans, he was a hero who refused to bow in the face of racism.

"I am the greatest. I said that even before I knew I was." rest in peace to a Legend. #GOAT

It was clear that the once-controversial boxer had been embraced into the mainstream.

Ali was a man who was proud of his religion and had changed his name to reflect his faith.

W. Kamau Bell, host of CNN’s “United Shades of America,” tweeted to “also remember that he was a Muslim.”
