Puerto Rico was originally inhabited by native Arawak people. It was discovered by Christopher Columbus in the 15th century and became a Spanish colony. Puerto Rico is now a self-governing commonwealth of the United States. There are three main political parties that have different views on Puerto Rico's relationship to the U.S.: those who want independence, statehood, or the current commonwealth status. Puerto Rico has a tropical climate and was largely deforested. The economy relies on tourism and industries like pharmaceuticals. Spanish is the main language and the dollar is the official currency.
