Elected pope
Emilio Altieri
Name taken: Clement X

The 1669–70 papal conclave (21 December – 29 April) was convened on the death of Pope Clement IX and ended with the election of Cardinal Emilio Altieri as Pope Clement X. The election saw deference within the College of Cardinals to Louis XIV of France, and a freeing of the cardinals loyal to Spain to vote according to their conscience. Eventually the elderly Altieri was elected with support of the major factions within the College.
