Puerto Rican Nationalists Griselio Torresola And Oscar Collazo Attempt To Assassinate President Harry S Truman
On October 30, 1950, Albizu-Campos and other nationalists led a 3-day revolt against the United States in various cities and towns of Puerto Rico.
The most notable occurred in Jayuya and Utuado. In the Jayuya revolt, known as the Jayuya Uprising, the United States declared martial law and attacked Jayuya with infantry, artillery and bombers. The Utuado Uprising culminated in what is known as the Utuado massacre. On November 1, 1950, Puerto Rican nationalists Griselio Torresola and Oscar Collazo attempted to assassinate President Harry S Truman. Torresola was killed during the attack, but Collazo was captured. Collazo served 29 years in a federal prison, being released in 1979. Don Pedro Albizu Campos also served many years in a federal prison in Atlanta, Georgia, for seditious conspiracy to overthrow the U.S. government in Puerto Rico.
Puerto Rico, Guam, the Philippines, and Cuba, ceded by Spain after the Spanish-American War in 1898, and for which the United States compensated Spain an additional $20 million under the terms of Article 3 of the Treaty of Paris. All four of these areas were under United States Military Government (USMG) for extended periods. Cuba became an independent nation in 1902, and the Philippines became an independent nation in 1946.
