Principality of Birkenfeld as the Principality of Lichtenberg, based in Sankt Wendel, however, it was already ceded to the Kingdom of Prussia. The Principality of Birkenfeld was now completely surrounded by the Prussian Rhine Province. As a result of the abdication and the renunciation of the succession to the throne of Frederick Augustus II, Grand Duke of Oldenburg on November 11, 1918, the Principality became the Birkenfeld district of the Rhine Province. The Saar region was separated from Germany and now administered by France. In 1935 the Saar was reunited with the German Reich under the name "Saarland", once again shuffling the administrative areas. The end of the Second World War in 1945 ushered in another substantial reorganization. Bosen, Eckelhausen, Eisen, Eiweiler, Gonnesweiler, Hirstein, Mosberg-Richweiler, Neunkirchen, Schwarzenbach, Selbach, Sötern, Steinberg-Deckenhardt, Türkismühle, and Walhausen were assigned to the new "Amt" Türkismühle in the Sankt Wendel district. In the joint meeting the mayors of all the towns, with the exception of Hirstein, supported the establishment of a new administrative grouping headquartered in Türkismühle, in the absence of suitable facilities for the temporary administrative headquarters in Gonnesweiler. Due to its geographic location Hirstein preferred a connection to the Namborn. In 1947 the municipality of Hirstein was spun off from the district of Türkismühle and incorporated into the administrative district of Namborn. With the Restructuring Act of 1973, the formerly independent communities were united. The legal successor of the Nohfelden Amt was the municipality (Gemeinde) of Nohfelden with the 13 districts: Bosen, Eckelhausen, Eisen, Eiweiler, Gonnesweiler, Mosberg-Richweiler, Neunkirchen, Nohfelden, Selbach, Sötern, Türkismühle, Walhausen and Wolfersweiler. Community partnerships Since 1996 Nohfelden has been a partner municipality with Jeleśnia, Poland. In April 2006 ten years of partnership was celebrated in Nohfelden with a large delegation from Jelesnia.
