Born into the crumbling palaces of desert tribes in 1923 (the precise date was not recorded), he now rules one of the richest countries on earth. When Abdullah was a child, his father had not yet finished his conquests on the Arabian Peninsula or founded the nation-state that bears the family name.The boy was 6 when his mother died, and as her only son he felt he had to take care of his younger sisters even then. "He had a tough childhood," says Abdullah's daughter Princess Adelah. "He took on a lot of responsibility from the time he was very young." The children grew up amid rebellion and insurrection, with their father's rule threatened by the intolerant Wahhabi Brotherhood that had helped bring him to power.As a grown man, Abdullah witnessed the oil boom and the corrosive effects of spectacular greed—and more fanaticism, more insurrection, including the bloody siege of the Great Mosque in Mecca in 1979. There were dangerous intrigues within the family, too. When Abdel Aziz died in 1953, the succession passed to his son Saud, who was deposed in 1964 by his half-brother Faisal, who was murdered years later by a nephew. When Fahd took the crown in 1982, Abdullah became crown prince, and after Fahd suffered a stroke in 1995, he became acting king.
