East Bend Township, a civil township, was created in 1860, after Champaign County adopted the township form of government, and originally comprised two survey townships.[5] The area had previously been known as Sodom, after an early post office, and the earliest European American settlers arrived in the late 1830s and early 1840s.[6] The western half of East Bend Township was set off in 1869 to create Brown Township.
