In 1838, Juan Pablo Duarte founded a secret society called La Trinitaria, which sought the complete independence of Santo Domingo without any foreign intervention. Also Francisco del Rosario Sánchez and Ramon Matias Mella, despite not being among the founding members of La Trinitaria, were decisive in the fight for independence. Duarte, Mella, and Sánchez are considered the three Founding Fathers of the Dominican Republic.
