Input: Question: How long had Prussia been a country for the year the French withdrew from the Rhine? Passage:In the course of the French occupation of the lands on the Rhine’s left bank in the wake of the Treaty of Lunéville, Rhaunen was grouped into the Department of Sarre, the arrondissement of Birkenfeld and the canton of Rhaunen. After the French withdrew in 1814, Rhaunen found itself in Prussia’s new Rhine Province, also becoming the seat of a Bürgermeisterei (“mayoralty”) in the Bernkastel-Kues district. Parts of the old high court district, however – Bundenbach, for instance – now belonged to the Principality of Birkenfeld, an exclave of the Grand Duchy of Oldenburg, most of whose territory was in what is now northwest Germany, with a coastline on the North Sea. Even after the First World War, through the Weimar Republic and on through the time of the Third Reich, Rhaunen was the administrative seat for the surrounding villages. In the course of administrative restructuring in the 1960s, the Amt of Rhaunen became the Verbandsgemeinde of Rhaunen in the Birkenfeld district. This arrangement still stands.
