Eugenio María de Hostos y de Bonilla, known as El Gran Ciudadano de las Américas, was a Puerto Rican educator, philosopher, intellectual, lawyer, sociologist, novelist, and Puerto Rican independence advocate.

Throughout the history of Puerto Rico, its inhabitants have initiated several movements to gain independence for the island, first from the Spanish Empire between 1493 and 1898 and since then from the United States. Today, the movement is most commonly represented by the flag of the Grito de Lares (Cry of Lares) revolt of 1868.
