Heretic Queen by Susan Ronald
As the Wars of Religion raged bitterly through Europe in the 16th century, Elizabeth was determined to grant a measure of religious tolerance to her subjects. Influenced by the protestant views of her infamous father, Henry VIII, and brother, Edward VI, as well as her Roman Catholic sister, Mary I, she and her advisers introduced the Elizabethan Religious Settlement that would forever shape religion in England and beyond.
But with threats from the continent coming thick and fast, her battle to defend her faith soon became tantamount with defending her realm. In this compelling book, which has been praised by many leading historians, Susan Ronald expertly weaves the story of Elizabeth I with the turbulent religious circumstances of her reign. Heretic Queen is a must read for anyone interested in the Elizabethan era or the English Reformation.
