Widen

At the end of the 12th century a manor called "Wyda" is mentioned the first time, there's no exact year. "Widen", in the way like it's written today, appears the first time during the 14th century.
In medieval times, the manor belonged to Habsburg. 1415 the Eidgenossen conquered the Aargau and Widen then belonged to the Grafschaft Baden. In March 1798 the French conquered Switzerland and proclamated the Helvetic Republic, in which Widen and Eggenwil formed one single municipality in the short-dated canton of Baden. After the foundation of the canton of Aargau 1803, Widen and Eggenwil were separated. Up to that time, there's not much known about Widen, because there are almost no documents left.
