Southeast Borneo Federation


Southeast Borneo Federation was an autonomous area formed in the southeastern part of Indonesian island of Borneo by the Netherlands in 1948 as part of an attempt to re-establish the colony of the Dutch East Indies during the Indonesian National Revolution. Southeast Borneo became a constituent part of the United States of Indonesia in 1949. The Federation was dissolved on 18 April 1950 and combined with Great Dayak and Bandjar to form South Kalimantan Province.
