Cuban revolutionary and politician Fidel Castro died yesterday at the age of 90. His brother Raúl Castro, his successor as Cuban president, announced his death on Cuban state television. Castro had made few public appearances in recent years, and in the rare photos meted out by the government during that time, he often looked to be in poor health, despite attempts to make it seem otherwise. Reactions to Castro’s passing are certain to be mixed, as the legacy he leaves behind him is one marked by contradictions and controversy.
