Ramón Emeterio Betances y Alacán was a Puerto Rican independence advocate and medical doctor. He was the primary instigator of the Grito de Lares revolt and designer of the Grito de Lares flag. Since the Grito galvanized a burgeoning nationalist movement among Puerto Ricans, Betances is also considered to be the father of the Puerto Rican independence movement and the El Padre de la Patria . His charitable deeds for people in need, earned him the moniker of El Padre de los Pobres .

Grito de Lares, also referred to as the Lares revolt, the Lares rebellion, the Lares uprising, or the Lares revolution, was the first of two short-lived revolts against Spanish rule in Puerto Rico, staged by the Revolutionary Committee of Puerto Rico on September 23, 1868. Having been planned, organized, and launched in the mountainous western municipality of Lares, the revolt is known as the Grito de Lares . Three decades after rebelling in Lares, the revolutionary committee carried out a second unsuccessful revolt in the neighboring southwestern municipality of Yauco, known as the Intentona de Yauco (The Attempted Coup of Yauco). The Grito de Lares flag is recognized as the first flag of Puerto Rico.
