Frank País was an important leader in the Cuban Revolution.
His first anti-Batista activities came in the early fifties. He was involved in the MNR (Movimiento Nacional Revolucionaria, or the National Revolutionary Movement), which approached Campamento Columbia in April of 1953, with the goal of winning the army there over to their side.
The small uprising failed, and the MNR fell apart.
País was an important student leader at the University of Santiago. The Santiago students sympathized with Fidel Castro in Havana, and País took a trip to meet him.
País instantly liked what he saw, and became active in the July 26 Movement. When Castro left Cuba to train his small army in Mexico, he made País the head of all M-26-7's "action groups" that were in Cuba. País would effectively run the show until Castro returned.
País led an attack on the headquarters of the police in 1956 at the same time the Granma landed. Several other assaults were made that day and the next, but eventually País withdrew.
País was assassinated by Batista's police on July 30, 1958; his brother had been killed a month earlier. País was only twenty-three.
