AI’s Answer:

The longest-lasting dictatorship in Latin America is the regime of the Castro family in Cuba. It began with Fidel Castro's rise to power in 1959 after the Cuban Revolution, overthrowing the Batista government. Fidel Castro ruled Cuba as a one-party state until 2008, when he officially handed over power to his brother, Raúl Castro. Raúl then ruled until 2018, marking nearly six decades of continuous rule by the Castro family. Though Raúl stepped down as President in 2018, the Communist Party of Cuba remains in control, with Miguel Díaz-Canel as the current President.
