The Frickgau is a geographical and political region that was first mentioned in 926 as Frichgowe . It is located in the northwest of what is now the canton of Aargau . When the Carolingians divided their area into Gaue in the 8th century , the Frickgau belonged to the Augstgau . Around the 10th century the Augstgau was then divided into the Sisgau in the west, the Buchsgau in the southwest and the Frickgau in the east. The borders of the Frickgau are formed by the rivers Aare and Rhine and the Möhlinbach in the west. The old border between the Aare and Möhlinbach is practically identical to the current canton border.

Arnold I. von Lenzburg was named as Landgrave in Frickgau in 1064 . In 1073 he was also castvogt of the Säckingen women 's monastery , which may have been closely related. In the 12th century, the lords of Alt-Homberg ( Thierstein-Homberg family ) held the title of Count in Frickgau for a time, but in 1173 Frickgau was again part of the Lenzburg heritage. Because Ulrich IV of Lenzburg appointed the emperor as heir, Friedrich I. Barbarossa lent both the castvogtei and the count's office in Frickgau to the counts of Habsburg on his court day in Säckingen in March 1173 after the Lenzburg family died out .

In 1799 French troops occupied the Fricktal . This ended the 400-year Austrian rule and the name Frickgau, which had been in use until then, was no longer used. On February 20, 1802, the canton of Fricktal was proclaimed a French protectorate . The canton was incorporated into the Helvetic Republic in August 1802 at the request of the cantonal authorities. On February 19, 1803, Napoléon Bonaparte ordered the dissolution of the canton and its connection, together with the canton of Baden , to the newly founded canton of Aargau.

The term "Fricktal" does not come from the name Frickgau; it did not appear as an area designation until the Napoleonic era. In Upper Austria the term Fricktal was only used for the area between Hornussen and Eiken . When the areas of Lower Austria south of the Rhine were finally separated, the French chose a uniform name for the entire area, which at that time was divided into three offices. Since the Fricktal was in the middle, its name was extended to the whole area.
