Castro's followers, known as the "Cuban Revolutionaries," included a diverse group of individuals such as students, intellectuals, workers, and peasants who were disillusioned with the Batista regime. Key figures among them were Che Guevara, Camilo Cienfuegos, and Raúl Castro. Many were motivated by a desire for social justice, land reform, and anti-imperialism, which ultimately led them to support Castro's revolutionary movement against the Cuban government in the 1950s.
