Succession of Maria I and Peter III. The throne passed to Joseph's daughter, Queen Dona Maria I, and to his brother and son-in-law, King Peter III. Maria became the first undisputed queen regnant of Portugal, and Peter automatically became co-monarch because a child had already been born of their marriage.
