ABOUT THE SPEAKERS

Rosa María Payá is the founder of Cuba Decide and a commissioner on the Inter-American Commission on Human Rights.

The regime responded in 2003 with what became known as the Black Spring, jailing 75 activists, many of them Varela organizers. Oswaldo Payá pressed on with his work until he died in a 2012 car crash that the Inter-American Commission on Human Rights later concluded was caused by agents of the Cuban state. Rosa María has continued her father’s work, documenting abuses before international bodies and building support for a binding plebiscite on Cuba’s political future.
