Mediatised houses
The mediatised houses (or mediatized houses; German: Standesherren) were ruling princely and comital-ranked houses that were mediatised in the Holy Roman Empire during the period from 1803 to 1815 as part of German mediatisation, and were later recognised during the period from 1825 to 1829 by the German ruling houses as possessing considerable rights and rank. With few exceptions, these houses were those whose heads held a seat in the Imperial Diet when mediatised during the establishment of the Confederation of the Rhine in 1806–07, by France in 1810, or by the Congress of Vienna in 1814–15.
