History

In ancient times Zofingen was a settlement of the Celtic Helvetii. In later times the Romans built a manor. The Alemanni settled in the 6th century and formed one of the oldest parishes in Aargau. In the 11th century the House of Frohburg founded a canons monastery. The town was founded in 1201 by the counts of Frohburg. 1231 was the first written mention of Zofingen, which in 1299 came into the possession of the Habsburgs. In 1415 the Bernese conquered the city and in 1528 they introduced the Reformation. Since 1803 Zofingen has belonged to the canton of Aargau and has become a regional center. The neighboring Mühlethal was incorporated in 2002.
