Final answer:
Queen Elizabeth I restored unity in England through the Elizabethan Settlement by retaining Catholic traditions but keeping England a Protestant nation, which brought stability to the country.
Step-by-step explanation:
Queen Elizabeth I was a major influence in restoring unity in England through the Elizabethan Settlement in the mid-1500s by retaining many Catholic traditions but keeping England a Protestant nation. Her compromises brought stability to the country and helped establish the Church of England as the state church, which retained the ceremony of the Catholic service but made changes such as priests saying mass in the vernacular and allowing them to marry. These compromises helped to maintain a balance between Protestants and Catholics and prevented further religious conflicts.
