Clemens August of Bavaria (German: Clemens August von Bayern; 17 August 1700 – 6 February 1761) was a member of the Wittelsbach dynasty of Bavaria and Archbishop-Elector of Cologne. Clemens August (Clementus Augustus) was born in Brussels, the son of Elector Maximilian II Emanuel of Bavaria and Theresa Kunegunda Sobieska and the grandson of King John III Sobieski of Poland. His family was split during the War of the Spanish Succession and was for many years under house arrest in Austria; only in 1715 did the family become re-united. His uncle Joseph Clemens, Elector and Archbishop of Cologne, saw to it that Clemens August received several appointments in Altötting, the Diocese of Regensburg, and at the Prince-Provostry of Berchtesgaden, and he soon received papal confirmation as Bishop of Regensburg, and later of Cologne. As Archbishop of Cologne, he was one of the Electors, a Prince-Bishop of Münster, Hildesheim, and Osnabrück, and a Grand Master of the Teutonic Order. Clemens August, who mostly sided with the Austrian Habsburg-Lorraine side during the War of the Austrian Succession, personally crowned his brother Charles VII emperor at Frankfurt in 1742. After Charles's death in 1745, Clemens August then again leaned toward Austria. Over time, Clemens August changed more frequently the alliances, as of Allied of Austria or France, also under the influence of his frequently changing First Ministers and high donations. He died in Festung Ehrenbreitstein in 1761. In March 1761, shortly after his death, Pope Clement XIII rejected the succession of Clemens August's brother Cardinal John Theodore of Bavaria as Archbishop and Prince-Elector of Cologne since the pope entertained some doubt on John Theodore's "moral conduct". This was the end of the reign of the Wittelsbach in Cologne after 178 years of continuous rule. In his will, Clemens August donated only to his successor as Elector and the court chamber of the Electorate of Cologne, but not the Elector of Bavaria.
