The arrival of European settlers in the late 18th century brought significant changes to Hamilton County. Originally part of Montgomery County, it was officially established as a separate county in 1816 and named after Alexander Hamilton, the first Secretary of the Treasury. The county's natural resources, such as timber and waterways, played a vital role in its early development.

In the 19th century, Hamilton County experienced a boom in logging and sawmill operations. The abundant forests attracted industries and workers, leading to the establishment of towns like Indian Lake, Speculator, and Wells. The lumber industry thrived until the early 20th century when the availability of timber declined, causing a shift in the local economy.
