In January 1966, Prince Sadruddin was appointed United Nations High Commissioner for Refugees after serving for three years as Deputy High Commissioner. At the age of 33 he became the youngest person ever to lead the UNHCR. For the next twelve years he directed the UN refugee agency through one of its most difficult periods, coordinating the international response to the 1971 Bangladesh crisis that uprooted people, the 1972 exodus of hundreds of thousands of Hutus from Burundi to Tanzania, and the Vietnamese boat people tragedy of the mid-1970s. In 1972, Prince Sadruddin played a key role in finding new homes for tens of thousands of South Asians expelled from Uganda by Idi Amin.
