Pope Innocent XI (Latin: Innocentius XI; Italian: Innocenzo XI; 16 May 1611 – 12 August 1689), born Benedetto Odescalchi, was head of the Catholic Church and ruler of the Papal States from 21 September 1676 until his death on 12 August 1689.
Political and religious tensions with Louis XIV of France were a constant preoccupation for Innocent XI. Within the Papal States, he lowered taxes, produced a surplus in the papal budget and repudiated nepotism within the Church. Innocent XI was frugal in his governance of the Papal States, his methods evident in matters ranging from his manner of dress to a wide range of standards of personal behaviour consistent with his conception of Christian values.
