Althann
Althann (also spelled Althan, Altham or Altheim) is the name of a German noble family from Lower Bavaria. They are one of the oldest extant German noble families, going back to at least 1129. By 1400, they had moved to Austria, where they were created barons, in 1574, and Imperial Counts, in 1610. After Brandenberg-Prussia annexed Silesia in the First Silesian War, a branch of the family joined the Prussian nobility. In the nineteenth century, they had seats in both the Austrian and Prussian "Herrenhauser", or House of Lords.

A list of notable members and possessions of the family may be found in the corresponding German Wikipedia article.
