1911 Encyclopædia Britannica/Clement/Clement X

Clement X. (Emilio Altieri) was born in Rome, on the 13th of July 1590. Before becoming pope, on the 29th of April 1670 he had been auditor in Poland, governor of Ancona, and nuncio in Naples. His advanced age induced him to resign the control of affairs to his adopted nephew, Cardinal Paluzzi, who embroiled the papacy in disputes with the resident ambassadors, and incurred the enmity of Louis XIV., thus provoking the long controversy over the regalia (see Innocent XI.). Clement died on the 22nd of July 1676.
