The Sac, Fox, Potawatomi, and Winnebago tribes had members in the area when settlers arrived. The first Europeans to settle in the area were French traders from Canada. The region about the Yahara River was called Gishkzhegonang by the Potawatomi peoples, and was transcribed into English as "Koshkonong." The Potawatomis called Lake Koshkonong as Éndayang-zagegen, but the early settlers began calling this lake in the Koshkonong region as Lake Koshkonong. The first settlers for farming arrived around 1836. In 1840, Norwegian families from Telemark settled near Lake Muskego in Waukesha County. In 1841, what would become for a time the largest Norwegian-American community in America was founded at Koshkonong in eastern Dane and western Jefferson counties. It was started by settlers from the Jefferson Prairie Settlement and the Fox River settlement. By 1850, over half of the Norwegian immigrants in Wisconsin lived in the Koshkonong settlement, known as Kaskeland in Norwegian.
