For Pedro de Luna, see Antipope Benedict XIII.

Benedict XIII, born Pietro Francesco Orsini, and later in religion Vincenzo Maria Orsini (Gravina di Puglia , February 2, 1649 - March 2, 1730) was pope from 1724 to 1730. He succeeded Innocent XIII in 1724. At first, he called himself Benedict XIV (due to the superstition alleging that the number thirteen brings bad luck), but afterwards altered the title. He was a reforming pope and endeavoured to put a stop to the decadent lifestyles of the Italian priesthood and of the cardinalate. He was a member of the great Orsini family of Rome, and the last member of that family to become Pope.
