The former Cuban president Fidel Alejandro Castro Ruz was born in 1926 in Biran, Cuba. His father was growing sugar cane, thus, his family was quite wealthy. When he was 24, Castro graduated the University of Havana with a degree in law. During his university days, Castro joined the Party of the Cuban People.

In 1953, several years after graduation, Fidel Castro went to jail for participation in the Moncada Barracks attack. Castro was sentenced to 15 years imprisonment, however, two years later he was released (owing to the public pressure). After imprisonment, Castro lived in Mexico for a year. In 1956, Fidel Castro returned on his native land.
