1960. Fidel closes the meeting of the Coordinators of the Sugarcane Cooperatives, held in the theater of the Central de Trabajadores de Cuba in Havana.

He recalls the conditions in which the peasants linked to the sugar harvest lived before 1959. He expresses: "In those enormous extensions of cane, man had been reduced to the condition of an inferior, humiliated being, dispossessed of everything..."

He points out how, after the triumph of the Revolution, the application of the Agrarian Reform was carried out and specifies: “... the distribution of the land was not done freely, the agrarian reform was not done freely. First, an awareness of what agrarian reform was was created in the town; it was made known not only to the peasants, but to the entire people, why an agrarian reform had to be carried out, what an agrarian reform was, and what benefits would be derived from the agrarian reform.”

And he adds: “When the agrarian reform became a reality in the conscience of the nation, it also became law, and it began to be applied.”
