Des Moines (/dəˈmɔɪn/ (listen)) is the capital and the most populous city in the U.S. state of Iowa. It is also the county seat of Polk County. A small part of the city extends into Warren County. It was incorporated on September 22, 1851, as Fort Des Moines, which was shortened to "Des Moines" in 1857. It is located on, and named after, the Des Moines River, which likely was adapted from the early French name, Rivière des Moines, meaning "River of the Monks". The city's population was 214,133 as of the 2020 census. The six-county metropolitan area is ranked 83rd in terms of population in the United States with 699,292 residents according to the 2019 estimate by the United States Census Bureau, and is the largest metropolitan area fully located within the state.
Des Moines is a major center of the US insurance industry and has a sizable financial services and publishing business base. The city was credited as the "number one spot for U.S. insurance companies" in a Business Wire article and named the third-largest "insurance capital" of the world. The city is the headquarters for the Principal Financial Group, Ruan Transportation, TMC Transportation, EMC Insurance Companies, and Wellmark Blue Cross Blue Shield. Other major corporations such as Wells Fargo, Cognizant, Voya Financial, Nationwide Mutual Insurance Company, ACE Limited, Marsh, Monsanto, and Corteva have large operations in or near the metropolitan area. In recent years, Microsoft, Hewlett-Packard, and Facebook have built data-processing and logistical facilities in the Des Moines area.
Des Moines is an important city in U.S. presidential politics; as the state's capital, it is the site of the first caucuses of the presidential primary cycle. Many presidential candidates set up campaign headquarters in Des Moines. A 2007 article in The New York Times said, "If you have any desire to witness presidential candidates in the most close-up and intimate of settings, there is arguably no better place to go than Des Moines."
Des Moines was nicknamed the Hartford of the West because like Hartford, Conn., it is an insurance center.
