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.

A local constitution was approved by a Constitutional Convention on February 6, 1952, ratified by the U.S. Congress, approved by President Truman on July 3 of that year, and proclaimed by Gov. Muñoz Marín on July 25, 1952, the anniversary of the 1898 arrival of U.S. troops. Puerto Rico adopted the name of Estado Libre Asociado (literally translated as “Free Associated State”), officially translated into English as Commonwealth, for its body politic.

During the 1950s Puerto Rico experienced rapid industrialization, due in large part to Operación Manos a la Obra (“Operation Bootstrap”), an offshoot of FDR’s New Deal, which aimed to transform Puerto Rico’s economy from agriculture-based to manufacturing-based. Presently, Puerto Rico has become a major tourist destination and a leading pharmaceutical and manufacturing center. Yet it still struggles to define its political status. Three plebiscites have been held in recent decades to resolve the political status but no changes have been attained. Support for the pro-statehood party, Partido Nuevo Progresista (PNP) and the pro-commonwealth party, Partido Popular Democrático (PPD) remains about equal. The only registered pro-independence party, the Partido Independentista Puertorriqueño (PIP), usually receives 3-5% of the electoral votes.

On October 25, 2006, the State Department of Puerto Rico conferred Puerto Rican citizenship to Juan Mari Brás. The Supreme Court of Puerto Rico and the Puerto Rican Secretary of Justice determined that Puerto Rican citizenship exists and was recognized in the Constitution of Puerto Rico. Since the summer of 2007, the Puerto Rico State Department has developed the protocol to grant Puerto Rican citizenship to Puerto Ricans.
