Dutch return to Bali in 1946

Following Japan’s Pacific surrender in August 1945, the Balinese took over the Japanese weapons. The Dutch returned to Indonesia in 1946, including Bali, to reinstate their pre-war colonial administration. One Balinese, Colonel Gusti Ngurah Rai, formed a Balinese ‘freedom army’. Colonel I Gusti Ngurah Rai, by then 29 years old, rallied his forces in east Bali at Marga Rana, where they were trapped by heavily armed Dutch troops. On 20 November 1946, in the Battle of Marga, the Balinese battalion was entirely wiped out, breaking the last thread of Balinese military resistance.
In 1946 the Dutch constituted Bali as one of the 13 administrative districts of the newly proclaimed State of East Indonesia, a rival state to the Republic of Indonesia which was proclaimed and headed by Sukarno and Hatta. Bali was included in the United States of Indonesia when the Netherlands recognised Indonesian independence on 29 December 1949.
