The story

How Pekin Township came to be

From Wikipedia’s history of Pekin Township.

Read it all →

Farmer Jonathan Tharp, who came from Ohio, was the first non-native American resident of what would become Pekin, building a log cabin in 1824 on a ridge above the Illinois River at a site near the present foot of Broadway Drive. Franklin School was later erected near this site. Other settlers soon joined him, including his father Jacob Tharp who arrived from Ohio in 1825. They lived near Chief Shabbona's large Indian village of about 100 wigwams, populated primarily by Potawatomi, which was situated along Gravel Ridge, on the eastern shore of what is today Pekin Lake in northwest Pekin.
