From Victims of Communism in Cuba: 73,000 (CNSNews):

As President Barack Obama currently visits Cuba, it merits noting that the Communist regime south of Florida has killed an estimated 73,000 people since the dictator Fidel Castro seized power in 1959, according to the Victims of Communism Memorial Foundation, which was established by an act of Congress in 1993.

The Victims of Communism Memorial Foundation, which runs the Museum of Communism, is a non-profit group created “to educate this generation and future generations about the ideology, history, and legacy of communism,” reads its website. It also is building a memorial “to commemorate the more than 100 million victims of communism” worldwide.
