When lead miner William S. Hamilton, the son of Alexander Hamilton, migrated from Illinois to Wisconsin in the late 1820s, he established a lead ore mine that became known as Hamilton's Diggings. He later renamed the settlement Wiota. Hamilton, along with Elias Shook and William Haws, settled the area in 1828 and quickly struck quality deposits of lead ore. During the 1832 Black Hawk War, a fort was erected at Hamilton's Diggings, which was known as Fort Hamilton. Wiota was first platted in 1836 by Hamilton, and though a few buildings were built, the settlement was eventually moved from the Hamilton's Diggings site to its present site, which was platted on July 1, 1858.
