Concepción de Gracia worked as a lawyer specializing in civil and constitutional law. In 1936, at the age of 25, he moved to New York to represent Pedro Albizu Campos and other members of the Puerto Rican Nationalist Party, who were jailed and appealing their case. Concepción de Gracia remained in New York, defending the civil rights of Hispanic workers and other minorities. He became more involved in politics, and particularly the cause of Puerto Rican independence from the United States. He befriended the like-minded congressmanVito Marcantonio, and took the editorship of a newspaper called La Voz.
Educator
Concepción de Gracia later became a professor of Hispanic literature at Middlebury College in Vermont. He then moved to Washington, D.C. and worked at the Panamerican Union, the organization which would later be known as the Organization of American States. In 1943, while he continued to pursue his Law education, Concepcion de Gracia joined a group called the 'Congress for Independence', which advocated the independence of Puerto Rico.
On October 20, 1946, the Puerto Rican Independence Party was created with Concepción de Gracia as its president. The PIP was registered as an official political party in 1948 and participated in that year's elections. It became the second-largest party in Puerto Rico in 1952, when it captured 20% of the electoral vote. Fifteen PIP members were elected to the House of Representatives of Puerto Rico that year. Concepcion de Gracia himself joined the Senate of Puerto Rico, and became the speaker for his party, a post which he held until 1960. That year, the Popular Democratic Party of Puerto Rico won the governorship and created a political status known as the Associated Free State. Concepcion de Gracia claimed that the new status was only a deceptive way to hide and continue the colonial relationship with the U.S. On July 25, 1952, Puerto Rico adopted a constitution establishing its status as a commonwealth. Concepción de Gracia and the PIP considered this status to be just another name for colonialism, and did not participate in the Constitutional Assembly.
Concepción de Gracia and Julio Pinto Gandía took Puerto Rico's case before the United Nations and sustained that Puerto Ricans should have the right to a consultation before being sent to any war. He also protested the sterilization practices in the U.S. of Puerto Ricans and the passive immigration of Puerto Ricans to the U.S. In 1955 he represented Puerto Rico in a conference held in Bandung, Indonesia sponsored by the United Nations. He also represented the PIP at the 1949 conference of the Organization of American States held in Havana, Cuba, and at the 1957 conference in Maracay, Venezuela. In 1964 he represented the PIP at a United States Congress commission on Puerto Rico's political status. Gilberto Concepción de Gracia died on March 15, 1968 in Santurce, Puerto Rico.
In memory
Concepción de Gracia's name has been attached to many places in Puerto Rico, including the beach on the contested island of Vieques where the PIP established a camp in 1999 during the Navy-Vieques protests. His native town of Vega Alta erected a statue in his honor in the town's square.
