In communist Cuba, the state own everything. No religion is allowed to be practice and the general idea of religion was suppressed. My grandparents were not communist, and if you weren't a communist, you were considered a dissenter of the government. Neighborhood "watchers" kept an eye out for dissenters and reported them to the government starting in 1960.
In 1964, a government official warned my grandfather that if he didn't leave the country, he would be thrown into prison for his known anti-communist beliefs. In political prisons, guards used abusive tactics such as beatings, arbitrary detention, extended solitary confinement, denial of basic healthcare, and execution.
My grandfather and one of his brothers owned an appliance store but the government seized and nationalized it. The government then forced him to use his training as an agricultural engineer for the five year sugar harvest. The working conditions were poor and the farm was on the other side of the island away from his entire family.
