Bretzenheim was a minor principality in pre-Napoleonic Germany. It was created in 1790 for Prince Charles Augustus (1769-1823) of the line of Wittelsbach-Bretzenheim, son of Charles Theodore, Elector of Bavaria and Palatinate. Its territory in central Germany was mediatised to Hesse-Darmstadt in 1803, and its territory north of Lake Constance was mediatised to Austria in 1804. Before 1789-1790 it was an Imperial Lordship and it had some important rulers, including Ambrosius Franz, Count of Virmont. In 1772 the Elector of Palatinate bought the Lordship (Imperial County 1774 ) for his son.
