The land around the modern village and what ever settlements were there belonged to the "Herrschaft" of Heimberg in the 13th century. The Heimberg's were under the authority of the Counts of Kyburg. On 11 November 1382, Rudolf II von Kyburg, attempted unsuccessfully to attack Solothurn. His attack started the "Burgdorferkrieg" (also "Kyburgerkrieg") with the Old Swiss Confederacy. Bern used the war to expand north into the Aargau and south into the Oberland. After the Kyburg defeat, as part of the peace treaty, Bern bought the city of Thun and all its surrounding lands including Teuffenthal. Under Bernese rule, the small farming village was part of the distant parish of Hilterfingen until 1928 when it joined the parish of Buchen. In 1935 Teuffenthal became an independent parish.
