Answer
Yes, Díaz-Canel's leadership is considered a non-dynastic form of succession. This is because he was not chosen as a successor to his father, Fidel Castro, but rather was elected by the Communist Party of Cuba to succeed Raúl Castro, who had served as president since 2008. Díaz-Canel's election marked the first time that a non-Castro had been elected president of Cuba since 1959, when Fidel Castro led the Cuban Revolution.
