Mesolithic siliceous rock objects and tools and
Hallstatt era graves indicate that the Othmarsingen area was prehistorically occupied. Othmarsingen is first mentioned around 1184-90 as
Otewizzingin. The modern municipality was formed from the village of Othmarsingen, part of the settlement along the north-west road and the village of Hüttwilen (which was last mentioned as an independent village in 1504). In the
Middle Ages the
high court right was held by the
Habsburgs, and after 1415 it was held by
Bern. The lower court right belonged to various aristocratic families until 1484 when it went to Bern. The court that constituted Othmarsingen also included,
Ammerswil,
Dintikon and
Brunegg in 1539 and was under a
bailiff. During the
Peasants War of 1653 Othmarsingen was heavily damaged. The village laws date from 1680 and 1734. In 1594 a teacher was active in the village and since 1657 there has been a private school. The southern part of the village was in the Ammerswil
parish while the northern part was in the
Staufberg parish. In 1528, the
Protestant Reformation spread into Othmarsingen from Bern. A chapel is mentioned in 1371 and 1421 with
Saint Mary as the patron. In 1593 this chapel was moved. In 1675 a new church was built, and in 1873 it became its own parish. There was a cotton processing factory in the village starting in 1760. Until
World War I there was, also, a
straw products factory. Othmarsingen has always has a good transport connection. In 1770, the expansion of the
Zurich-Bern road came through the village. In 1877, the
National Railway came through and in 1882 it was connected to the
Aargau Southern Railway. In 1975, the
Heitersberg railway line was added. ==Geography==
