Map - Boniswil

Boniswil is a municipality in the district of Lenzburg in the canton of Aargau in Switzerland.

Boniswil is first mentioned around 1217–22 as Bonoltswile. The village was ruled by the Counts of Lenzburg, then the counts of Kyburg and then the Habsburgs and finally in 1415 the city of Bern. The rights to low justice were held by the Habsburg vassals, the lords of Rinach in the 13th century. These rights, in turn, came in 1486 to the possession of the lords of Hallwyl and passed in 1616 to Bern. Einsiedeln Abbey collected rent on about three fifths of the land in the village.

Religiously, it was part of the Seengen parish until 1842 when it joined Leutwil parish.

In the 18th century, the major economic sources in the village were the cotton industry with home spinning and weaving and agriculture. In the 19th century, cotton was replaced by the straw industry. The construction of the Seetalbahn train line in 1883 brought economic recovery and new industries (tobacco, box factories). Since 1950 a number of new buildings were added to the municipality. In 1990 only 6% of the local jobs were in agricultural sector, while about 53% were in services. 73% of the population commutes outside the municipality for work, while 49% of jobs in the municipality are filled by commuters.
