Who was Fidel Castro's power base?

Fidel Castro's power base primarily consisted of the urban working class, students, and intellectuals who were disillusioned with the existing government and socioeconomic conditions in Cuba. He also garnered significant support from rural peasants, particularly through his agrarian reform policies. Additionally, Castro's alignment with leftist ideologies and anti-imperialist sentiments resonated with various groups, helping him build a broad coalition that ultimately enabled his successful revolution in 1959.
