Ulrika Eleonora supported the political ambitions of her consort, and from the beginning, she wished for him to become her co-monarch, in the fashion of William III and Mary II. However, this was not permitted by the Riksdag. One reason being that co-reigning had been forbidden in Sweden since the 15th century. There was also opposition in the Riksdag to the influence of Emerentia von Düben and her siblings over the affairs of state. Her difficulty in respecting the constitution and trouble in getting along with the Riksdag, as well as her way of continuously discussing state affairs with her husband, did however make the Riksdag willing to replace her with Frederick as sole monarch if she abdicated, an idea that had the support of Frederick. On 29 February 1720, after having again been denied a co-monarchy, Ulrika Eleonora abdicated in favour of her husband on the condition that she should succeed him if he should die before her. This condition of her abdication in fact granted her place as the heir to the Swedish throne until her death.
