Leopold Ignaz Joseph, Prince of Dietrichstein, was a German prince member of the House of Dietrichstein, 4th Prince of Dietrichstein zu Nikolsburg, Princely Count of Tarasp, Baron of Hollenburg, Finkenstein and Thalberg.
Background
He was the third child and second (but eldest surviving) son of Ferdinand Joseph, 3rd Prince of Dietrichstein, and Marie Elisabeth, daughter of Johann Anton I, Prince of Eggenberg, Duke of Český Krumlov and Princely Count (gefürsteter Graf) of Gradisca d"Isonzo.
Career
After returning to the Imperial court, Leopold Ignaz Joseph was named Privy Councillor. Due to the high position and authority of his father, Prince Ferdinand Joseph, at court, he had great hopes and expectations for his future. However, these hopes were not fulfilled.
Historian Rostislav Smíšek refers to some rumours about the young prince that circulated at court, which in 1685 completely stopped the progress of Leopold Ignaz Joseph in the political hierarchy.
His renewed career was stopped by his early death in 1708 at the age of 48, from tuberculosis.
Membership
His first high appointment took place only in 1705, when he was named a member of the Imperial Chamber.
