Curaçao (ˈkjʊərəsoʊ,_-saʊ,ˌkjʊərəˈsoʊ,-ˈsaʊ , , , or , kyːraːˈsʌu or kuːr-, Kòrsou ˈkɔrsɔu̯), officially the Country of Curaçao (Land Curaçao; Pais Kòrsou), is a Lesser Antilles island in the southern Caribbean Sea and the Dutch Caribbean region, about north of the Venezuela coast. It is a constituent country of the Kingdom of the Netherlands. Together with Aruba and Bonaire, it forms the ABC islands. Collectively, Curaçao, Aruba, and other Dutch islands in the Caribbean are often called the Dutch Caribbean. It is the largest of the ABC islands in both area and population as well as the largest of the Dutch Caribbean. Curaçao was formerly part of the Curaçao and Dependencies colony from 1815 to 1954 and later the Netherlands Antilles from 1954 to 2010, as Island Territory of Curaçao (Eilandgebied Curaçao, Teritorio Insular di Kòrsou), and is now formally called the Country of Curaçao. It includes the main island of Curaçao and the much smaller, uninhabited island of Klein Curaçao ("Little Curaçao"). Curaçao has a population of 158,665 (January 2019 est.), with an area of ; its capital is Willemstad. One explanation for the island's name is that Curaçao was the autonym by which its indigenous peoples identified themselves. Early Spanish accounts support this theory, referring to the indigenous peoples as Indios Curaçaos. From 1525, the island was featured on Spanish maps as Curaçote, Curasaote, Curasaore, and even Curacaute. By the 17th century, it appeared on most maps as Curaçao or Curazao. On a map created by Hieronymus Cock in 1562 in Antwerp, the island was called Qúracao. A persistent but undocumented story claims the following: in the 16th and 17th centuries—the early years of European exploration—when sailors on long voyages got scurvy from lack of vitamin C, sick Portuguese or Spanish sailors were left on the island now known as Curaçao. When their ship returned, some had recovered, probably after eating vitamin C-rich fruit there. From then on, the Portuguese allegedly referred to the island as Ilha da Curação (Island of Healing) or the Spanish as Isla de la Curación.
