About Prince-Bishop of Liege Adolf II Graf von der Mark
The Prince-Bishopric belonged from 1500 on to the Lower Rhenish–Westphalian Circle. Its territory included most of the present Belgian provinces of Liège and Limburg, and some exclaves in other parts of Belgium and the Netherlands.
It briefly became a republic (the Republic of Liège) from 1789 to 1791, before reverting to a Prince-Bishopric in 1791. The role of Prince-Bishop permanently ended when the state was annexed by France in 1795. In 1815 it became part of the United Kingdom of the Netherlands, and in 1830 it was within the part of that kingdom which split off to become Belgium.
