Eiken

The land was probably already occupied in the Roman era and individual objects from the Alamanni and Frankish Empire eras. Eiken is first mentioned in the first half of the 12th Century as Eitchon. The municipality of Sisseln was originally an expansion of Eichen, and it remained part of the municipality until 1806, when it became independent.

Under the Habsburgs, Eichen was the center of the bailiwick of Eichen. The municipality bought its own Twingherrschaft, which gave it local self-rule and limited court rights, in the 16th century. Eiken belonged to the Austrian Fricktal until 1803 when it went to the newly formed canton of Aargau.
