The Earldom of Hanau-Lichtenberg lost most of its population during the 30 Years War. The authorites invited settlers from
Switzerland into the area. Around 3000 Swiss followed the invitation, 2400 from Bern. People from Simmental settled in Obersulzbach, the people from Diemtigtal settled in Rauschenburg and the ones from Oberaargau in Schalkendorf.
