After the pomp and celebrations associated with the imperial wedding, the success of the union became contingent upon the queen’s ability to produce a male heir. Although he had been married twice before, the Shah’s previous marriages had given him only a daughter who, under agnatic primogeniture, could not inherit the throne. The pressure for the young queen was acute. The shah himself was deeply anxious to have a male heir as were the members of his government. Thankfully, the couple had four children, Crown Prince Reza in 1960, Princess Farahnaz in 1963, Prince Alireza in 1966, and Princess Leila in 1970.
