Hamengku Buwono IX, the late Sultan of Yogyakarta Special Province, is revered by Indonesians as one of the great founders of the modern Indonesian state. He leaves a positive but in some ways ambiguous legacy in political terms. His most conspicuous achievement was the survival of hereditary Yoqyakartan kingship, and he provided rare stability and continuity in Indonesia's highly fractured modern history. Under the New Order, Hamengku Buwono also helped to launch the Indonesian economy on a much stronger growth path. Although remembered as the epitome of "political decency", he faded from power and influence as Vice President in the 1970s, and the repressive and anti-democratic features of Suharto's New Order seemed to contradict much of what Hamengku Buwono originally stood for. This biography seeks to explain his political standpoint, motivations, and achievements, and set his career in the context of his times.
