The Puerto Rican Nationalist Party insurgency was a series of coordinated insurrections for the secession of Puerto Rico led by the president of the Puerto Rican Nationalist Party, Don Pedro Albizu Campos, against the United States government's rule over the islands of Puerto Rico. The party repudiated the "Free Associated State" status that had been enacted in 1950 and which the Nationalists considered a continuation of colonialism.
