The Spanish Virgin Islands (), formerly called the Passage Islands (Spanish: Islas del Pasaje) and also known as the Puerto Rican Virgin Islands (, Islas Vírgenes Puertorriqueñas), West Virgin Islands (Spanish: Islas Vírgenes Occidental, Islas Vírgenes Occidentales) primarily consisting of the islands of Culebra and Vieques, are part of the Commonwealth of Puerto Rico and are located east of the main island of Puerto Rico in the Caribbean. Despite its name, the islands are no longer under Spanish sovereignty. History Archaeological works in Vieques indicate that the island of Vieques was inhabited by indigenous groups from South America around 1,500 years before the arrival of Christopher Columbus in 1493. The inhabitants of Vieques, brothers of the Taínos of the Big Island of Puerto Rico, resisted the Spaniards' plans of colonization and slavery. It has been documented that Christopher Columbus discovered the island of Culebra on his second trip to America in 1493. It is believed that the first known inhabitants of the island were the Taíno Indians and then the Caribs. Culebra Island served as a refuge for many defeated Taíno Indians during the rebellion against the Spanish in 1511. English from Vieques's neighboring British colonies—Tortola, Anguilla, Saint Kitts and Nevis—established themselves in Vieques on several occasions throughout the 17th and 18th centuries. In 1688, and later in 1717, these English tried to colonize Vieques, establishing hamlets, a military fort, an English government, and extensive farming. In both cases the Spanish governor in Puerto Rico sent strong military expeditions and successfully evicted the English "invaders" and thus assured Spanish domination over Vieques. In 1875, the Spanish Crown made an effort to populate the island of Culebra. But it was not until 1880 that the colonization of Culebra began with the founding of the town of San Idelfonso de la Culebra. Like Puerto Rico, the islands belonged to Spain until 1898. On September 19, 1898, the United States took possession of the islands after the signing of the armistice that ended military operations in the Spanish–American War. The islands, along with the islands of Puerto Rico, Mona, Monito, Desecheo, and other smaller islands adjacent to the island of Puerto Rico, were formally ceded by Spain to the United States with the signing of the Treaty of Paris on December 10, 1898. In 1903 the U.S. government reserved all public lands belonging to the Spanish Crown on the island of Culebra for
