[1] Prior to and following European settlement in Illinois, Tiskilwa (formerly called Indiantown) was a Potawatomi village.

[4][5][6] In 1836, Augustus Langworthy platted and established a town called Windsor where Tiskilwa now stands.

Tiskilwa emerged as a regional economic and cultural center integrating its own administrative capacities, schools, churches and shops serving a small population of townspeople and farm families from the surrounding 3 to 5 miles (5 to 8 km).

It was a small community whose center was three blocks of Main Street around which were located its churches, cafes, taverns, grocery stores, beauty parlors, barbershops and other businesses.

The festival offers fresh berries and strawberry shortcake, live entertainment, children's activities and food vendors in downtown Tiskilwa from late morning through early afternoon.

[citation needed] Tiskilwa celebrates Pow Wow Days annually during first weekend in August.

This is a three-day event with a community concert or big band dancing, children's "Little Spurs Rodeo" (which was discontinued in 2021), a parade, a Native American pow wow, a beer garden, 4-H Club and cheerleader-sponsored food stands, church-sponsored lunches, historical tours, antique automobiles and tractors, and other events.
