The Puerto Rican Nationalist Party was founded in 1922 to advocate for the independence of Puerto Rico from the United States. The party aimed to promote Puerto Rican culture and identity while opposing U.S. colonial rule. It gained prominence in the 1930s and 1940s, organizing protests and political activities to raise awareness about Puerto Rico's status. The party is known for its radical approach, including acts of violence, such as the 1950 Jayuya Uprising. Key figures included Pedro Albizu Campos, who became a prominent leader advocating for independence. The party's influence has waned over the years, but it remains a significant part of Puerto Rican political history.
