Background
Before the arrival of the
French missionaries, the swampy area was inhabited by small settlements of Native Americans on the southern coast of Lake Michigan. Their community was made up of
Algonquian people of the
Mascoutens
The Mascouten (also ''Mascoutin'', ''Mathkoutench'', ''Muscoden,'' or ''Musketoon'') were a tribe of Algonquian-speaking Native Americans located in the Midwest. They are believed to have dwelt on both sides of the Mississippi River, adjacent to ...
and
Miamis tribes, which hunted the area. The French missionaries were the first Europeans to come into this region. The settlements of Algonquian people in the area were used as trading posts on the trade routes by the French fur traders and trappers. The word ''Chécagou'' was probably coined by the French from the native word ''shikaakwa'', which means "
wild leek" or "
skunk weed".
History
Seventeenth century settlement attempts
A number of small, temporary fortified trading posts were constructed in the area in the late seventeenth century. The exact location of most of these trading posts is uncertain, and, although they were sometimes referred to as "forts," there is no evidence of a permanent French military fortification in the area during this period.

In a letter written by the explorer
de LaSalle dated June 4, 1683, he notes that two of his men had constructed a temporary
stockade
A stockade is an enclosure of palisades and tall walls, made of logs placed side by side vertically, with the tops sharpened as a defensive wall.

Further evidence that Durantaye's fort was not located beside the Chicago River comes from the journals of
Henri Joutel.
In October 1687 Joutel, and a party of de LaSalle's men left Fort St. Louis bound for Canada. When they arrived at Lake Michigan, however, poor weather prevented them from going any further. After waiting for eight days by the lake at the mouth of the Chicago River, they gave up and returned to Fort St. Louis. They set out again in March 1688, arriving at Chécagou on March 29, and leaving on April 8. Joutel described their stay in the area, but made no mention of any fort.

Myth of a French Fort Chécagou is born
The myth of a French fort at the mouth of the Chicago River emerged following the publication of a map of Lake Michigan by
Louis Hennepin
Louis Hennepin, OFM (born Antoine Hennepin; ; 12 May 1626 – 5 December 1704) was a Belgian Catholic priest and missionary best known for his activities in North America. A member of the Recollects, a minor branch of the Franciscans, he travel ...
in 1698 (see map, above). His map showed
Fort Miami near the mouth of the St. Joseph River, however, he showed the river as emerging from the southernmost tip of the lake. Hennepin's map was widely copied, but cartographers—knowing that there was no river at the southern tip of Lake Michigan—erroneously assumed that Hennepin had intended to show the Chicago River, and so it became widely accepted that there had been a French fort at the mouth of the Chicago River.
