The territory was ceded in the Black Hawk Purchase of 1832. The first European-American settlers established a village they called Lilienthal, after an early tavern and dance hall. The village of Gilbert developed alongside Lilienthal in 1858, honoring Elias Gilbert, who platted the original site. At that time, the residents were predominantly German immigrants and worked as farmers, skilled laborers, and small business owners. The two villages eventually combined to become the town of Gilbert.
