A
HistoryA character grade: shown, never part of Edwardsville Township’s overall grade.
Few Illinois towns list much on the Register (a typical Illinois town has 0.5 per 10,000 residents, the U.S. 2.4), so Edwardsville Township’s 104 sits above most of its state (94% of Illinois towns have fewer) while its 422 historic buildings outnumber those of 97% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from B+ to A. The pre-1940 share (±2.0 points) is firm at this size. Two sources give 1818.

What stands out about Edwardsville Township’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
Edwardsville was incorporated in 1818. The first European-American settler was Thomas Kirkpatrick, who came in 1805, laid out a community, and served as the Justice of the Peace. He named the community after his friend Ninian Edwards, then territorial governor of Illinois. (Illinois did not become a state until 1818.) The Edwards Trace, a key trail in the settlement of Central Illinois, used Edwardsville as a northward launching point.
In 1868 The Bank of Edwardsville was founded. It was purchased by Champaign, Illinois-based Busey Bank in 2019.
