What was Mary 1st doing when edward 6th was on the throne?

During Edward VI's reign, Mary I was largely in a position of opposition due to her status as a Catholic and her brother's Protestant policies. She faced political and religious persecution, which led her to remain largely in the background while Edward ruled. However, she was actively involved in plotting against Edward's government, seeking to restore Catholicism in England. After Edward's death in 1553, Mary eventually ascended to the throne and began her campaign to re-establish Catholicism.
