Who was Mary II?

Answer 1

Mary II was daughter of James II and VII, who was the second son of Charles I. Charles I was the son of James I and VI, the successor to Elizabeth I. Mary was therefore a Stuart, and Reigned as Queen from 1689 until her death in 1694. She reigned jointly with William III. William III reigned alone after the death of Mary. Mary II was Queen Regnant, like the two Elizabeths, and not just the consort to William, because she had an equal claim to the throne. I am not certain but I believe that this is the only such joint reign or co-regency in the history of England/Great Britain. Their reign is usually referred to as William and Mary. They were first cousins.
