(NBC News/Phil McCausland) — Former Cuban President Fidel Castro has died at 90, his brother Raúl Castro announced on Cuban television Friday night.
Castro resigned his role as president in Feb. 2012, allowing his brother Raúl to take over as president.
The CIA announced in Nov. 2005 that it had concluded that Castro suffered from Parkinson's disease. Their assessment stemmed from Castro's public appearances and the opinions of doctors employed by the agency.
It is unknown if Parkinson's disease had a role in Castro's death.
Castro played a crucial role in the Cuban Revolution that overthrew Cuban President Fulgencio Batista in 1959. After assuming control of the country, he established strong diplomatic and economic ties to the Soviet Union, which caused friction between Cuba and the United States.
Under his leadership, the United States and Cuba experienced the Bay of Pigs invasion in 1961, the Cuban Missile Crisis in 1962 and the Mariel Boatlift in 1980 that caused 120,000 Cuban migrants to move to the United States.
As a result, the United States placed a number of trade and travel restrictions on Cuba. Barack Obama lifted a number of these restrictions in Dec. 2014. He was also the first U.S. president to visit the island country in 88 years when he visited in 2016.
