menziken is first mentioned in 1045 as "manzinchouen" though that comes from a 14th century copy of the original document. in 1295 it was mentioned as "menzchon". however, the current site of menziken was settled earlier. both roman era ruins and alamanni graves have been discovered in the municipality. during the high middle ages it was owned by the counts of lenzburg. in 1173 it passed over to the kyburgs and following the extinction of the kyburg line, in 1273 it passed to the habsburgs. the habsburgs held the rights to high justice while their vassals, the lords of reinach, held the rights to low justice. from the conquest of aargau in 1415 until the creation of the helvetic republic in 1798, the village was under bernese domination. at that time, menziken belonged to the district () of lenzburg. with the creation of the canton of aargau through the act of mediation in 1803, menziken became a municipality in the new canton.
