The State of East Indonesia (Indonesian: Negara Indonesia Timur, old spelling: Negara Indonesia Timoer) was a post–World War II federal state (negara bagian) formed in the eastern Dutch East Indies by the Netherlands. It was established in 1946, became part of the United States of Indonesia in 1949 at the end of the Indonesian National Revolution, and was dissolved in 1950 with the end of the USI. It comprised all the islands to the east of Borneo (Celebes, and the Moluccas, with their offshore islands) and of Java (Bali and the Lesser Sunda Islands).
