The first indigenous president of Bolivia, Evo Morales, on Thursday highlighted the centenary of the historic leader of the Cuban Revolution, Fidel Castro, stating that his voice continues to accompany those who fight for a better world.

In a post on his Facebook account, the former president wrote: “We celebrate the life and the 100 years of our commander, Fidel Castro. A revolutionary who never renounced his convictions and embraced his duty when history called him to fight for his people.”

Morales described the author of History Will Absolve Me as a “teacher who sowed hope when others sowed resignation.”

The former Aymara dignitary added that the leader of the Revolution that triumphed on January 1, 1959, was “a brother who taught us that loyalty to the people is worth more than any reward and weighs more than applause.”

Morales accompanied his text with a video explaining how, following Fidel Castro’s suggestion and assistance—through the so-called Operation Miracle, which provided sight-restoring surgeries to populations in need—more than 700,000 Bolivians received this benefit.
