The Ludovingians or Ludowingians (German: Ludowinger) were the ruling dynasty of Thuringia and Hesse during the 11th to 13th centuries.
Their progenitor was Louis the Bearded who was descended from a noble family whose genealogy cannot be precisely determined. Like the related Reginbodo family, they had a close relationship with the Archbishopric of Mainz and also had estates on the Middle Main.
Eisenach (German pronunciation: [ˈaɪzənax] ) is a town in Thuringia, Germany with 42,000 inhabitants, 50 kilometres (31 miles) west of Erfurt, 70 km (43 miles) southeast of Kassel and 150 km (93 miles) northeast of Frankfurt. It is the main urban centre of western Thuringia, and bordering northeastern Hessian regions, is near the former Inner German border. A major attraction is Wartburg castle, which has been a UNESCO World Heritage Site since 1999.
Eisenach was an early capital of Thuringia in the 12th and 13th centuries. St. Elizabeth lived at the court of the Ludowingians here between 1211 and 1228. Later Martin Luther came to Eisenach and translated the Bible into German. In 1685 Johann Sebastian Bach was born here. During the early modern period Eisenach was a residence of the Ernestine Wettins and was visited by numerous representatives of Weimar classicism like Johann Wolfgang Goethe. In 1869 the SDAP, one of the two precursors of the Social Democratic Party of Germany (SPD), was founded in Eisenach.
