Chaska is a city in Carver County, Minnesota, United States. The population was 23,770 at the 2010 census. It is the county seat of Carver County, which is part of the Minneapolis-St. Paul-Bloomington, MN-WI Metropolitan Statistical Area.HistoryChaska's history reflects the influence of the Native American culture. The first inhabitants are believed to be the Mound Builders, whose ancient communities are marked by mounds in City Square. Later, the Dakota (commonly known as the Sioux) were the primary nation in this region known as the Big Woods. Although the Indian mounds located in Chaska City Square indicate the immediate area was inhabited years before 1769, that's the year Chaska's recorded history began.In 1776, Jonathan Carver explored the lands along the Minnesota River and chronicled his journeys. French Canadian fur traders traveled the waterways, trading with the Dakota in the early 19th century. During this time, Jean-Baptiste Faribault established a trading post in Chaska.In 1851, the Treaty of Traverse des Sioux officially opened Little Rapids, as Chaska was then known, to settlement. Soon after, speculators moved into the new territory. Among the earliest was Thomas Andrew Holmes who, in August 1851, claimed a 20acre clearing as the Chaska townsite.
