Farming conditions in the southern part of the province of Västergötland were frequently poor. Even before the 16th Century, farmers in the area developed a cottage industry in ironwork and woodwork as a way of supplementing their incomes. Later on, wood handicrafts, spinning and weaving were added.
All products were sold to hawkers, called "knallare" in Swedish, who travelled between farms throughout a large area, and visited fairs and permanent outlets. In fact, this type of trade, known as "lands-köp" (trade through intermediaries in rural areas), was prohibited in Sweden at the time.
In 1620, King Gustavus Adolphus II decided that the farmers in Västergötland had to register for census purposes in an existing town, or found a new town where they could be registered.
The following year, a town was formed beside Torpa Church on the River Viskan. The town was probably named after a farm in the area called Buerås – "the farmers by the ridge".
