Fidel Castro, the Cuban revolutionary who ran a communist state and defied the U.S. for 50 years, passed away on Friday (Nov. 25) at the age of 90.

According to the Associated Press, the deceased leader’s brother, Raul Castro, appeared on state television on Friday night to announce Fidel's death. "At 10:29 at night, the chief commander of the Cuban revolution, Fidel Castro Ruz, died," he said, without revealing a cause of death. "Ever onward, to victory," he added, using the slogan of the Cuban revolution.

Fidel Castro had been in declining health for several years, stepping aside in 2006 when he was felled by a serious gastrointestinal illness. The Cuban government declared that nine days of national mourning will commence for their late leader. A burial ceremony will be held on Dec. 4.

Born on Aug. 13, 1926, in eastern Cuba's sugar country, Mr. Castro became an imposing leader over Cuba who pushed his socialist ideologies and remained widely respected in parts of the world that struggled against colonial rule. However, he was also vilified by the United States and its allies for almost pushing the world into nuclear war and for his alleged killings and torturing of Cuban Dissents. Throughout his life, Fidel Castro has survived over 600 assassination attempts, according to Cuban officials.

Reactions to Fidel Castro’s death were mixed. In Miami, where many exiles from Castro's government live, people celebrated in the streets waving Cuban flags and banged on pots and pans. Meanwhile, Cubans who lived on the island are wondering what happens next. Their future economic progression feels hopeless now that Donald Trump is the U.S. President-elect.

Rapper Nas went on his Instagram page today (Nov. 26) and praised the deceased Cuban dictator. Posting a black-and-white photo of Fidel sitting with the late Muslim leader Malcolm X, he wrote, "RIP KING FIDEL CASTRO #revolutionary only 5% understand. I'm not Cuban, I don't fully know how he effected my Cuban family, so I'm sending strength and power for your pains. But lots Of us, as Black people, n some others in the USA, we saw him as Ally in the Struggle."
