In the seventeenth century the Sauk also maintained close relations with the Potawatomi (Pehkînenîha or Shîshîpêhinenîha). This relation has been found by borrowings of Sauk vocabulary that appear in the Potawatomi language. In a loose coalition of tribes – including Dakota (Ashâha), Ojibwe, Odawa, Potawatomi, Kickapoo (Kîkâpôwa), Meskwaki (Fox), and Sauk, along with the Shawnee (Shâwanôwa), Cherokee (Shanahkîha), and Choctaw (Châkitâha) from the Southeast – they attacked the tribes of the Illinois Confederation ("Illinois/Inoca") (Mashkotêwa) and tried to invade their tribal areas. The "Illinois/Inoca" became their worst common enemies. The coalition warred for years until they destroyed the Illinois Confederation. Later they moved out on the prairie (Mashkotêwi) along the Mississippi and adopted the semi-sedentary lifestyle of Plains Indians (Mashkotêwineniwa). In addition to hunting buffalo, they lived in villages, raised crops, and actively traded with other tribes. The Sauk and allied eastern tribes had to compete with tribes who already occupied this territory. Disputes and clashes arose with the Dakota, Pawnee (Pânîha) and, most of all, the powerful Osage (Washâsha). The Sauk had good relations with the English (Thâkanâsha) through trading. At first, the Sauk had good relations with New France too, until their alliance with the Meskwaki (Fox) made them short-term enemies of the French (Mêmehtekôshîha, Wêmehtekôshîha). A closely allied tribe, the Meskwaki (Fox), were noted for resisting French encroachment, having fought two wars against them in the early 18th century.

Notes
1.^  The name of the Sauk River in Washington State, however, comes from the Sah-kee-ma-hu (Sauk-Suiattle tribe), a group related to the Skagit tribes, not from the Sac tribe of the Midwestern U.S.
