(CNN)Former Cuban leader Fidel Castro has died at age 90, Cuban state media reported.
"There are few individuals in the 20th century who had a more profound impact on a single country than Fidel Castro had in Cuba," Robert Pastor, a former national security adviser for President Jimmy Carter in the 1970s, told CNN in 2012.
"He reshaped Cuba in his image, for both bad and good," said Pastor, who died in 2014. "Cuba will be a different place because he lived and he died."
Castro lived long enough to see a historic thaw in relations between Cuba and the United States. President Barack Obama announced in December that the United States would re-establish diplomatic relations with Cuba and urged Congress to lift a 52-year-old economic embargo.
