About Portage Des Sioux
Portage Des Sioux ( POR-tij duh SOO) is a city in St. Charles County, Missouri, United States. The town sits on the Mississippi River roughly opposite Elsah, Illinois, and is the home of the riverside shrine of Our Lady of the Rivers. As of the 2020 census, Portage Des Sioux had a population of 335. The city was founded in 1799 by Spanish Lt. Gov. Zenon Trudeau and François Saucier in reaction to American plans to build a military post about twelve miles (19 km) downstream. The French name derives from the overland escape route between the Missouri River and Mississippi River used by a band of Sioux, fleeing enemies; they used this area as a portage for their canoes, outdistancing their rivals who instead paddled all of the way to the confluence of the rivers.
The Treaties of Portage des Sioux in 1815 were signed here ostensibly settling Native American and United States conflicts in the War of 1812. The treaties consolidated and affirmed the Treaty of St. Louis (1804) in which the Sauk and Meskwaki ceding northeast Missouri and much of Illinois and Wisconsin and the 1808 Treaty of Fort Clark in which the Osage Nation ceded all of Missouri and Arkansas. These treaties were to ultimately result in the Black Hawk War and the tribes being forced to move west of Missouri.
