Fearing the Dutch would attempt to re-establish their authority over Indonesia, the new Republican Government and its leaders moved quickly to strengthen the fledgling administration. Within Indonesia, the newly formed government, although enthusiastic, was fragile and focused in Java (where focused at all). It was rarely and loosely in contact with the outer islands, which had more Japanese troops (particularly in Japanese naval areas), less sympathetic Japanese commanders, and fewer Republican leaders and activists. In November 1945, a parliamentary form of government was established and Sjahrir was appointed Prime Minister.
