Mohammad Reza fled the country, seeking medical treatment in Egypt, Mexico, the United States, and Panama, and finally resettled with his family in Egypt as a guest of Anwar Sadat. On his death, his son Crown Prince Reza Pahlavi succeeded him in absentia as heir apparent to the Pahlavi dynasty. Reza Pahlavi and his wife live in the United States in Potomac, Maryland, with three daughters.
