Leaders of "El Grito de Lares" went into exile in New York City. Many joined the Puerto Rican Revolutionary Committee, founded on December 8, 1895, and continued their quest for Puerto Rican independence. In 1897, Antonio Mattei Lluberas and the local leaders of the independence movement in Yauco organized another uprising, which became known as the "Intentona de Yauco". They raised what they called the Puerto Rican flag, which was adopted as the national flag. The local conservative political factions opposed independence. Rumors of the planned event spread to the local Spanish authorities who acted swiftly and put an end to what would be the last major uprising in the island to Spanish colonial rule.
