Finds of golden coins, potsherds and bits of tools dating from Roman times have led to the conclusion that there was already a settlement of some kind here as early as the 3rd century. Deudesfeld had its first documentary mention in 1171 when the knight Ludwig von Deudesfeld was mentioned by name as a witness. Among other things, the founding of the Cistercian Saint Thomas's Convent on the Kyll can be traced back to him in connection with an extensive donation that brought Deudesfeld a dependence lasting centuries. Only when the convent's holdings were sold off under French rule, which began in 1794, was the bond with the ecclesiastical order broken. Deudesfeld's allegiance to the Electorate of Trier also ended with the coming of the French.
