by the marriage, christina became queen, and her son was legitimized. they were both included in the new will, which excluded his sons-in-law, which had been his previous heirs, specially ivar axelsson, whom he had previously appointed his successor. the king therefore appointed his nephew sten sture the elder as regent until his son was old enough to be elected king, and also gave him the task to protect their right to inherit him in his new will. the marriage caused controversy because of the difference in rank. bishop henrik tidemansson of linköping wrote a poem to illustrate the contemporary controversy over the marriage, where he stated that the marriage took place against the royal council and caused a great hatred toward king charles because he was considered to have made a bad example. christina was the only royal mistress in sweden to have become queen alongside karin månsdotter (1568).
