Herzogtum Franken
Conrad (died 27 February 906), called the Old or the Elder, was the Duke of Thuringia briefly in 892–93. He was the namesake of the Conradiner family and son of Udo of Neustria. His mother (probably) was a daughter of Conrad I of Logenahe (832–860). He was the count of the Oberlahngau (886), Hessengau (897), Gotzfeldgau (903), Wetterau (905), and Wormsgau (906). He united all of Hesse under his political control and under his heirs this territory became the Duchy of Franconia.
