Albizu Campos, Pedro (pāˈdrō älbēˈsō kämˈpōs) [key], 1891–1965, Puerto Rican political leader. After service in an African-American unit during World War I he developed a lasting enmity for the United States and became the fiery champion of Puerto Rican independence. His Nationalist party, however, failed to receive popular support in the Puerto Rican elections of 1932. Convicted of seeking to overthrow the U.S. government, he was imprisoned (1937–43) before returning to Puerto Rico in 1947. His party made a poor showing in the 1948 election, and in 1950 Nationalists attacked the governor's mansion in Puerto Rico and Blair House in Washington. Charged with inciting to murder, Albizu Campos was again imprisoned. He was pardoned (1953) because of failing health, but the next year he was implicated in the Nationalist armed attack on the U.S. House of Representatives, and his pardon was revoked. He was sentenced to life imprisonment. He suffered a stroke in 1956 and was again pardoned in 1964.
