After the Dutch East Indies, on behalf of the Dutch government transferred its sovereignty to the Republic of Indonesia, the new federated state called the United States of Indonesia was formed out of former Dutch territories in the East Indies and several states formed prior to the round table conference held in 1949. The new federation adopted a constitution in which stated in the Chapter III, article III, is that the official flag of the United States of Indonesia is a bicolor red and white, similar to the one that was adopted by the State of the Republic of Indonesia.
