How much power did Bloody Mary have?

Mary I of England, commonly known as Bloody Mary, ruled from 1553 to 1558. As queen, she wielded significant power, being the first woman to hold the English throne in her own right. Her reign was marked by her attempts to reverse the Protestant Reformation and restore Roman Catholicism, leading to the persecution of Protestants. Despite her authority, her reign faced challenges, including political opposition and a lack of popular support, ultimately resulting in her relatively short time in power.
