Mary was born as a princess of the Italian Duchy of Modena. She is mostly remembered for the birth of James Francis Edward. Most of the English people thought he was not really Mary's son. They believed he had been secretly brought into the birth-room in a warming-pan to continue King James II's Catholic rule. The privy council investigation declared that the story was false. However, James Francis Edward's birth was one of the reasons why the Glorious Revolution happened. In the Glorious Revolution, King James II was deposed by his daughter Mary and her husband William III of Orange.
