However, the next year, 1554, a group of rebels under Thomas Wyatt, including Jane's father Henry Grey, led a rebellion against Queen Mary because she was planning to marry prince Phillip II of Spain. It was quickly put down. Although Jane had nothing to do with it and Mary did not want to kill her cousin, her advisors told her that Phillip would only come if Jane was killed. So, with a heavy heart (sadly), Queen Mary signed the death warrant. Jane was going to be beheaded.
