Final answer:
Jane Grey, Elizabeth, and Mary were all Queens of England. Jane Grey was briefly the monarch, Elizabeth I ruled during the Elizabethan Settlement, and Mary I was known for her persecution of Protestants.
Step-by-step explanation:
The Ladies Jane Grey, Elizabeth, and Mary referred to in your question are Queens of England. Lady Jane Grey, often known as the 'Nine Days' Queen', was an English noblewoman who occupied the English throne from July 10 until July 19, 1553. Elizabeth refers to Elizabeth I, the longest-reigning Tudor monarch, who is remembered for her role in the Elizabethan Settlement — an attempt to resolve religious tensions between Catholics and Protestants in England. Mary primarily refers to Mary I of England, also known as 'Bloody Mary', for her persecution of Protestants. These women played pivotal roles during the sixteenth and seventeenth centuries.
