McKinley Park, one of the 77 official community areas of Chicago, Illinois, is located on the city's southwest side. History McKinley Park has been a working-class area throughout its long history. Settlement began around 1836 when Irish immigrants working on the Illinois & Michigan Canal took squatter's rights to small tracts of land in the area. By the 1840s, a few farmers had purchased and drained land, displacing the Irish squatters. Brighton was plotted in 1840 and incorporated in 1851. The completion of the Illinois & Michigan Canal in 1848 and the arrival of the Chicago & Alton Railroad in 1857 spurred further subdivision of the area. The rails amplified the transportation advantages of the area, and during the Civil War, industries grew along the waterways and the railroad. The Union Rolling Mill was founded in 1863 along the south fork of the Chicago River and produced 50 tons of rail per day. Eventually, the firm became part of U.S. Steel. The Rolling Mill employed many newly arrived Welsh immigrants, who lived in nearby homes on Ashland and Archer Avenue's. Many steelworkers lived in the triangle formed by Ashland Avenue, Archer Avenue and 35th Street in an area called Mt. Pleasant. The name was probably ironic, because of the adjacent steel mills, and because much of the area was swampy and undrained. Standing water bred hordes of mosquitoes, and spring flooding was so severe that many houses were built on stilts. Not surprisingly, a portion of McKinley Park was called "Ducktown." Some landowners desperate to elevate their holdings invited scavengers to dump ashes and thereby fill low areas. Unfortunately the scavengers dumped not only ashes, but garbage as well. Thus the area was not only wet, but fetid. Even with these problems, McKinley Park was annexed to Chicago in 1863. The fire of 1871 displaced numerous industrial operations and many relocated to this area. Within five years after the fire, 11 factories opened—most in iron and steel—along with 27 brickyards. During this same period, meatpacking operations just to the south moved into high gear. The result was the creation of the solid working-class community that still exists today. The packing houses fouled the environment and dumped wastes directly into the south fork of the Chicago River. Here the stream was such a hellish mess of decomposing material that a tributary became known as "Bubbly Creek" because of the bubbles that
