Kloster Muri
Oberwil-Lieli is first mentioned in 1040 as "Willare" in a land grant to Einsiedeln Abbey. During the 12th Century, Engelberg and Muri Abbey were also given grants in the village. The rights to high and low justice were held by the Counts of Habsburg-Laufenburg. Their rights came in the 14th Century to the lords of Schönenwerd and the knight Heinrich Biber, but in 1352 they went to the Family Stagel of Zurich. In 1429, the sovereign rights were granted to Bremgarten. After 1415 Oberwil was under the high justice of the city of Zurich.
