Like his son after him, his life in exile was short. After the United Kingdom and the Soviet Union invaded and occupied Iran on 25 August 1941, the British offered to keep his family in power if Reza Shah agreed to a life of exile. Reza Shah abdicated and the British forces quickly took him and his children to Mauritius, then to Durban, thence Johannesburg, South Africa, where according to his British captors, he died on 26 July 1944 of a heart ailment about which he had been complaining for many years. His personal doctor had boosted the King's morale in exile by telling him that he was suffering from chronic indigestion and not heart ailment. He lived on a diet of plain rice and boiled chicken in the last years of his life. He was sixty-six years old at the time of his death.
