Geopolitical events significantly shaped the biography of Fidel Castro, particularly his rise to power during the Cuban Revolution. The Cold War dynamics and U.S.-Cuba relations created a context of heightened conflict, influencing Castro's policies and ideology. The U.S. embargo and interventionist tactics catalyzed his commitment to socialism and land reforms, which he sought to implement as sovereignty measures. Furthermore, the support from the Soviet Union during this period bolstered Castro’s regime, enabling him to remain in power for decades. Castro's leadership was thus deeply entwined with the broader movements of communism and anti-imperialism on a global scale.
