On 30 August 1727, George II created his eldest daughter Princess Royal, a title which had fallen from use since its creation by Charles I for his daughter Mary in 1642. In 1725, a potential marriage contract between Anne and King Louis XV of France was considered. From a French viewpoint, such a marriage could give France valuable neutrality from The Netherlands and Prussia, as well as protection against Spain. However, the religious issues caused problems. The plan was eventually discarded when the French insisted that Anne must convert to Roman Catholicism. On 25 March 1734 in the Chapel Royal at St. James’s Palace, she married William IV, Prince of Orange. She then ceased to use her British title in favour of the new one she gained by marriage. The music played at her wedding, This is the day was set by Handel to the princess’s own words. Handel also composed an operatic entertainment, in honour of her wedding which was performed for the first time at the King’s Theatre, London, on 13 March 1734, with great success. William suffered from a spinal deformity, which affected his appearance, but Anne said she would marry him even “if he were a baboon”. Her reason for being so insistent upon this marriage was reported to be simply that she wished to be married, to avoid a life as a spinster at the court of her father and her brother, with whom she did not get along and as the only match considered suitable for her was with a monarch or heir to a throne, William was essentially her only remaining Protestant choice, and when questioned by her father, she stated that it was not a matter of whether she should marry William, the question was rather whether she should marry at all. She quarreled with her brother, the Prince of Wales, about her choice.
