Luis Muñoz Rivera was a Puerto Rican poet, journalist and politician. He was a major figure in the struggle for political autonomy of Puerto Rico in union with Spain.

The resident commissioner of Puerto Rico is a non-voting member of the United States House of Representatives elected by the voters of the U.S. Commonwealth of Puerto Rico every four years, the only member of the House of Representatives who serves a four-year term. Because the commissioner represents the entire territory of Puerto Rico irrespective of its population, and is not subject to congressional apportionment like those House members representing the 50 states, Puerto Rico's at-large congressional district is the largest congressional district by population in all of the United States.
