帝国代表者会議主要決議
In the German mediatization between 1803 and 1806, the vast majority of the Estates of the Holy Roman Empire were mediatised. They lost their imperial immediacy and became part of other Estates. The number of Estates was reduced from about three hundred to about thirty. Mediatisation went along with secularisation: the abolition of most of the ecclesiastical Estates. This dissolution of the constitution of the structure of the empire was soon followed by the dissolution of the empire itself, in 1806.
