Before European settlers arrived, there was a Native American village in what is today downtown Aurora, on the banks of the Fox River. In 1834, following the Black Hawk War, the McCarty brothers arrived and initially owned land on both sides of the river, but sold their lands to the Lake Brothers on the west side.A post office was established in 1837, officially creating Aurora. Actually, however, Aurora was originally two villages: East Aurora, incorporated in 1845, on the east side of the river, and West Aurora, formally organized on the west side of the river in 1854. In 1857, the two towns joined officially incorporated as the city of Aurora.
