German mediatisation was the major redistribution and reshaping of territorial holdings that took place between 1802 and 1814 in Germany by means of the subsumption and secularisation of a large number of Imperial Estates, prefiguring, precipitating, and continuing after the dissolution of the Holy Roman Empire. Most ecclesiastical principalities, free imperial cities, secular principalities, and other minor self-ruling entities of the Holy Roman Empire lost their independent status and were absorbed by the remaining states. By the end of the mediatisation process, the number of German states had been reduced from almost 300 to 39.
