Charles Joseph (German: Karl Joseph) (7 August 1649 – 27 January 1664) was an Archduke of Austria and Grand Master of the Teutonic Knights (1662 - 64). He was also the Bishop of Olmütz, and Breslau, Passau.
Charles Joseph was born on 7 August 1649, in Vienna to parents Ferdinand III and Maria Leopoldine. Destined for a life in the clergy, he was appointed as the Bishop of Passau and Olmütz at the young age of 13, following in the footsteps of his uncle Archduke Leopold Wilhelm.[1] [2] He also became the Grand Master of the Teutonic Order.[3] [4]
Due to his youth, Charles Joseph was unable to attain higher orders as a bishop. He passed away at the age of 14 on 27 January 1664, in Linz, Austria, due to exhaustion from battling an illness.[5] His remains were transported by ship to Vienna, where he was laid to rest in the Imperial Crypt on 21 February 1664.
