United States Housing Corporation (U.S.H.C.) Historic District is a nationally recognized historic district located in Rock Island, Illinois, United States. It was listed on the National Register of Historic Places in 2024. The historic district is made up of two discontinuous units and it includes 393 resources, which consists of 206 contributing buildings and 187 non-contributing buildings. The houses that make up this district were part of 638 houses constructed between 1918 and 1919 by the United States Housing Corporation (U.S.H.C.) in the Tri-Cities, now known as the Quad Cities. The local project area was referred to as the Rock Island District. At the time, there was a housing shortage in the area and a significant number of new workers were needed at the Rock Island Arsenal and other area manufacturers to produce supplies and munitions for the United States Army during World War I. St. Louis landscape architect George Kessler was hired to plan the Rock Island development. Rock Island contractor Henry W. Horst built the houses designed by the local architectural firm of Cervin and Horn. The houses were both single-family detached and semi-detached houses. The Tri-Cities housing committee favored permanent housing over temporary, and the houses were designed in styles that were popular at the time. The project came to an early end when the Armistice to end the war was signed in November 1918. The project in the city of Rock Island was far enough along that it was completed in full. It was one of the few U.S.H.C. projects in the country to be completed. Of the 900 houses planned in the Rock Island District, 110 houses were completed in neighboring Moline, 111 were completed in East Moline, 200 were completed in Rock Island, and 217 were completed across the Mississippi River in Davenport, Iowa. The houses in Iowa were designed by the architectural firm of Temple & Burrows and built by Central Engineering Company, both from Davenport. Initially, the houses were rented. The Rock Island District houses were the first U.S.H.C. houses to be sold, and this local sale set a pattern for the sale of the houses built in the rest of the country.

The Rock Island Arsenal Museum in Rock Island County, Illinois is based around the history of Rock Island Arsenal. It is the second oldest museum of the United States Army, the oldest being the Museum at West Point.

The Rock Island Arsenal comprises 946 acres (383 ha), located on Arsenal Island, originally known as Rock Island, on the Mississippi River between the cities of Davenport, Iowa, and Rock Island, Illinois. It lies within the state of Illinois. Rock Island was previously used as the summer camp site for Sauk Native Americans, and the dispute over tribal ownership led to the Black Hawk War of 1832, after the primary leader of the Sauk, Black Hawk. It is now home of First Army headquarters, and the US Army's Center of Excellence for Additive Manufacturing. The island was originally established as a government site in 1816, with the building of Fort Armstrong. It is now the largest government-owned weapons manufacturing arsenal in the United States. It has manufactured military equipment and ordnance since the 1880s. In 1919–1920 one hundred of the Anglo-American or Liberty Mark VIII tanks were manufactured, although too late for World War I. It is designated as a National Historic Landmark. Established as both an arsenal and a center for the manufacture of leather accoutrements and field gear, today it provides manufacturing, logistics, and base support services for the Armed Forces. The Arsenal is the only active U.S. Army foundry, and manufactures ordnance and equipment, including artillery, gun mounts, recoil mechanisms, small arms, aircraft weapons sub-systems, grenade launchers, weapons simulators, and a host of associated components. Some of the Arsenal's most successful products include the M198 and M119 towed howitzers, and the M1A1 gun mount. About 250 military personnel and 6,000 civilians work there. The 2000 census population was 145.
