Founded in 1845, Indianapolis reached its peak in the 1880s. After talks of a railroad linkage[2] from Clinton and Oskaloosa fell through, the population began to decline.
Indianapolis contained a post office from 1850 until 1902.[3] Indianapolis was named by settlers from Indianapolis, Indiana in the late 1840s.
