The Proclamation of Indonesian Independence (Indonesian: Proklamasi Kemerdekaan Indonesia, or simply Proklamasi) was read at 10:00 on Friday, 17 August 1945 in Jakarta. The declaration marked the start of the diplomatic and armed resistance of the Indonesian National Revolution, fighting against the forces of the Netherlands and pro-Dutch civilians, until the latter officially acknowledged Indonesia's independence in 1949. The document was signed by Sukarno (who signed his name "Soekarno" using the Van Ophuijsen orthography) and Mohammad Hatta, who were appointed president and vice-president respectively the following day.
