Islamic state
The Darul Islam rebellion was a war waged between 1949 and 1962 by the Islamic State of Indonesia, commonly known as Darul Islam, to establish an Islamic state in Indonesia. The rebellion began when Sekarmadji Maridjan Kartosuwirjo, a nationalist who had resisted the Dutch during the Indonesian National Revolution, refused to recognize the new Republic of Indonesia. Instead, he proclaimed the establishment of the Islamic State of Indonesia on 7 August 1949.
