The United States declined to recognize the new Cuban government, although many European and Latin American nations did so. In 1878, the Pact of Zanjón ended the conflict, with Spain promising greater autonomy to Cuba. In 1879–80, Cuban patriot Calixto García attempted to start another war known as the Little War but failed to receive enough support. Slavery in Cuba was abolished in 1875 but the process was completed only in 1886. An exiled dissident named José Martí founded the Cuban Revolutionary Party in New York in 1892. The aim of the party was to achieve Cuban independence from Spain. In January 1895, Martí traveled to Monte Cristi and Santo Domingo in the Dominican Republic to join the efforts of Máximo Gómez. Martí recorded his political views in the ''Manifesto of Montecristi''. Fighting against the Spanish army began in Cuba on 24 February 1895, but Martí was unable to reach Cuba until 11 April 1895. Martí was killed in the Battle of Dos Rios on 19 May 1895. His death immortalized him as Cuba's national hero.
