Jose Marti assured in a poem that he elaborated in 1872 dedicated to honor the medical students shot in Cuba by the Spanish authorities on November 27, 1871:

What is evidenced by Marti is particularly significant in the life and work of Fidel Castro who, beyond his death in Havana on November 25, 2016, continues to be a source of teaching and motivation for our people and for many men and women in different parts of the world for the importance of its existence, the validity of its principles and the work done.

Precisely on December 3, 2016, at the ceremony held in the Plaza de la Revolución Antonio Maceo y Grajales, in Santiago de Cuba, the city where the ballot box with the ashes of Fidel would be deposited the next day in a simple yet grandiose stone In the Santa Ifigenia cemetery the following day, Army General Raúl Castro Ruz after summarizing the qualities of the leader of the Cuban Revolution and his decision to always march forward, overcome the difficulties and demonstrate that if possible, he highlighted:

"That is the unbeaten Fidel who summons us with his example and with the demonstration that Yes it was possible, yes it can and yes it will be possible!"

Born in the area of Biran, in the current province of Holguin, on August 13, 1926, Fidel Alejandro Castro Ruz, developed the first stage of his childhood on the farm owned by his father. He used to interact with the children of the workers of the farm and even attended his first stage as a student in the public school existing in the area.

About this period of his existence he would point out several decades later when he spoke at the University of Havana, on September 4, 1995:

Already between 1931 and 1932 he was sent to Santiago de Cuba to continue his primary studies. There he met poverty and had to endure limitations, since although his father sent the necessary money to be adequately cared for, the family that initially lodged him in his home had low economic resources, and in practice the money quoted was used more for his survival while he lacked many things. Later he studied a time interned in the school center of Santiago.

Years later, in the Cuban capital, he began studying at the school of the Jesuits, at the school of Belen, which had a good material base and installation. In this center he achieved great prestige, mainly because he proved to be a good sportsman and also someone very fond of excursions.

In the yearbook of the school, corresponding to the course in which he graduated, a picture of him appears with the following words:

In the course that began in September 1945, the young Fidel Castro began studying law. Fifty years after the moment in which he began his studies at the University of Havana, on the occasion of speaking at the ceremony that took place on the campus of the capital to remember that moment of his life, Fidel would point out in this regard:

"In this university I experienced difficult moments, very difficult, so difficult that it is a true chance, even having survived those university years. I fought very hard struggles, with all the persistence and all the necessary decision, until afterwards other years and other times approached. "

Fidel also stated that he became a revolutionary at the University of Havana. And from that stage of his youth he not only thinks about the problems that Cuba suffered, but also feels like his the situation of other peoples that were affected by despotic and even dictatorial governments, as was the case of Santo Domingo.

It was like that when he was only twenty years old that he became involved with a contingent that was preparing in Cuba to support the Dominicans in their struggle against the dictator Trujillo. In 1947, from Cayo Confites, in the north of the eastern part of Cuba, it leaves in a boat that had the purpose of reaching the Dominican territory. Finally the expedition was intercepted at sea and there was the arrest of those who were in the boat. But Fidel threw himself into the sea and avoided being captured. Later he manages to return to Havana.

In the initial stage of 1948 he travels to Colombia. In that year, an international meeting was planned to create the Organization of American States, OAS, under the auspices of the United States of America. Prior to that, Fidel conceived the idea of ​​holding a congress of Latin American students to carry it out simultaneously in the same country where the event related to the OAS took place. In Colombia he was able to establish contact with Jorge Eliécer Gaitán, a politician who enjoyed great prestige within the town. On April 9, Gaitan was murdered. That same day, Fidel planned to hold a second meeting with him.

When the murder of Gaitan was known, the people of the Colombian capital took to the streets. Fidel then decided to participate in the protest demonstrations. He was persecuted and had to remain hidden in certain places or move from one place to another to avoid being arrested or killed. It was not until April 12 that finally, almost by chance, he was able to leave Bogota for Cuba.

After his return to Havana he continued his studies at the University and also began to interact with members of the Partido del Pueblo Cubano, an organization commonly known as the Orthodox Party, which was created in 1947 by Eduardo Chibas. He sympathizes with Chibas' proposals in his fight against corruption and other evils that affected Cuban society.

At the beginning of the 50s, Cuba was living an era characterized by the demoralization of the authentic government, headed then by Carlos Prio. The situation was chaotic, corruption was generalized by both the President and his ministers and other political leaders.

Since 1950, Fidel had graduated as Doctor in Law. Then, in union with two of his fellow university students, he opened a law firm in the area of ​​Old Havana. He was interested in an essential way to defend the rights of humble people, workers and peasants, and also assumed the accusation of those who had committed the murder of a young revolutionary in 1951, Carlos Rodríguez.

At the same time, Fidel continues to participate in activities of a political nature. From the end of 1951, he also carried out investigations into corruption, including that of President Carlos Prío himself.
Precisely, Fidel did not limit himself to obtaining that information, but he divulged it through the newspaper "Alerta". Fidel also denounced all this in a report that he directed on March 3, 1952, to the Court of Accounts, which was the highest inspection body of the Republic of Cuba at that time. After specifying the corrupt actions of President Prío, he said when presenting considerations on the critical situation existing in the country:

"Cuba, converted into a land of fierce caines, on the road to suicide, made a den and a den of a few rampant, desperately turns its eyes to ask of you the miracle that can save it from the constitutional and moral collapse that threatens it."

A week after having exposed this approach, Fulgencio Batista's coup d'etat took place on March 10, 1952. Precisely, given the demagogic statements of Batista that intends to present the conspiracy as a revolutionary movement, the young lawyer Fidel Castro, in a document that he writes a few hours after the coup d'état took place emphatically states:
