The Constitution of Puerto Rico 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, on the anniversary of the July 25, 1898, landing of U.S. troops in the Puerto Rican Campaign of the Spanish-American War, until then an annual Puerto Rico holiday. Puerto Rico adopted the name of Estado Libre Asociado (literally "Free Associated State", officially translated into English as Commonwealth), for its body politic. The United States Congress legislates over many fundamental aspects of Puerto Rican life, including citizenship, currency, postal service, foreign affairs, military defense, communications, labor relations, the environment, commerce, finance, health and welfare, and many others.
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, as well as a global center for pharmaceutical manufacturing. 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
