Explanation:

Fidel Castro was a lawyer, military, politician and revolutionary Cuban Marxist. He was president of his country as prime minister (1959-1976) and president (1976-2008) after his victory in the Cuban revolution against the dictatorship of Fulgencio Batista.

During his mandate, Cuba became a Marxist-Leninist socialist state, under the leadership of the Communist Party of Cuba, the only legal entity on the island since his arrival in power and nationalizations and expropriations of productive means were carried out with the objective of carrying out a socialist economic policy.

In the international arena, he initially tried to establish good relations with the United States; He then established close ties with the Soviet Union. After a series of expropriations to US owners, the disagreements with the United States led to the economic embargo against Cuba. Since then, his relationship with the superpower has been openly antagonistic, which was confirmed after the failed invasion of the Bay of Pigs in 1961.

Despite the iron-fisted US opposition, Fidel Castro received dozens of national and foreign decorations. Due to its long management and the controversial characteristics of its policies, a controversial and intense debate has been generated between opponents and supporters about its Government: from qualifying it as a dictatorship to considering it the expression of the will of the Cuban people.
