After the Japanese occupation of the Dutch East Indies and the
Proclamation of Indonesian Independence, he contacted
Sam Ratulangi, then-governor of newly formed Sulawesi province to discuss the Indonesian Republic position and decided to support the republic establishment. He later formed a paramilitary organization named
Soekarno Moeda (lit: Young Sukarno). He negotiated and convinced other traditional rulers in the region to support Indonesian Republic and reject any cooperation with
Netherlands Indies Civil Administration. His paramilitary would later be under his own son, Andi Makkalau, and attacked several Japanese positions to steal their weapons. This ultimatum was ignored and a widespread attack started on 23 January 1946 involving the Royal Netherlands East Inies Army and also the
Australian army who were also attacked by militias. This would be followed by the
South Sulawesi campaign of 1946–1947, and Andi would be arrested by the Dutch on 3 July 1946 and exiled to
Ternate. He was sentenced to death but reduced to 25 years imprisonment and soon released after the
Dutch–Indonesian Round Table Conference. He stayed on in his position as king of Luwu and a civil servant until he died on 23 February 1965. == Awards and legacy ==
