Boxing great Muhammad Ali died on Friday at the age of 74 after being hospitalized in Arizona with a respiratory issue. Ali also had suffered from Parkinson’s disease for about 30 years.

Ali was a legend in and out of the ring, and when the news broke of his passing, people from all over the world — from athletes to artists and beyond — reacted with sadness and appreciation.
