The Prince's love life had always been the subject of press speculation, and he was linked to numerous glamorous and aristocratic women. In his early thirties, he was under increasing pressure to marry. Legally, the only requirement was that he could not marry a Roman Catholic; a member of the Church of England was preferred. His great-uncle Lord Mountbatten of Burma, who was assassinated by an IRA bomb in 1979, had advised him to marry a virginal young woman who would look up to him. In order to gain the approval of his family and their advisors, any potential bride was expected to have a royal or aristocratic background, as well as be Protestant and, preferably, a virgin. Diana seemed to meet all of these qualifications. They married at St Paul's Cathedral on the 29 July 1981, watched by a global audience of almost one billion.
