Just two days after Japan's surrender, Sukarno and Mohammad Hatta read a brief proclamation of independence from the porch of Sukarno's Jakarta home. The Dutch refused to recognize it, triggering years of guerrilla warfare and diplomacy before the Netherlands finally conceded sovereignty in 1949. The date is now Indonesia's most important national holiday.
The proclamation itself took less than a minute to read: two sentences, typed hastily overnight after younger nationalists pressured Sukarno and Hatta to act before Allied forces could reimpose colonial order. There was no grand stage, no crowd of thousands—just a modest gathering outside a house on Pegangsaan Timur street, a hand-sewn red-and-white flag raised on a bamboo pole, and a recording made almost as an afterthought.
The Dutch, exhausted from Nazi occupation at home, were unwilling to simply let go of their most valuable colonial possession. They returned with troops within weeks, sparking the Indonesian National Revolution, a brutal conflict marked by both diplomacy and massacre on both sides. Sukarno and Hatta were briefly captured and exiled by the Dutch in 1948 before international pressure, including from the United States, forced the Netherlands to the negotiating table.
Today, August 17 is celebrated across Indonesia with flag ceremonies, panjat pinang pole-climbing competitions, and a formal reading of the same two-sentence proclamation. Sukarno's original typed copy, edited by hand in his own scrawl, survives as one of Southeast Asia's most treasured documents.
