Springfield, Illinois

Springfield is the capital city of the U.S. state of Illinois.

It sits on a plain near the Sangamon River, just north of Lake Springfield.

The city serves as the county seat for Sangamon County. It is also located along the historic Route 66. As a capital, it houses the government of the entire state. This makes it a vital center for law and administration in the region.

The economy of Springfield is largely driven by government activity. Many residents work for state agencies or firms that support state and county governance. Healthcare and medicine also provide major employment for the city. Several key institutions are located here. These include the Illinois General Assembly and the Illinois Supreme Court. The office of the Governor of Illinois is also based in the city.

The historic Illinois Governor's Mansion is another important state site.

Springfield's history began with trappers and fur traders in 1818.

In 1820, John Kelly built the first cabin in the area. He chose a hill overlooking a creek called Town Branch. He found the area had plenty of deer and wild game. The community was originally named "Calhoun" after Senator John C. Calhoun. In 1821, it became the county seat because of its fertile soil. By 1832, the town changed its name to Springfield. Local history suggests the name came from Spring Creek.

Abraham Lincoln is the most famous person to have lived in Springfield.

He arrived in the area in 1831 but moved to the city in 1837. He lived and worked there for 24 years as a lawyer and politician.

Lincoln and other lawmakers helped make Springfield the state capital in 1839. Before this, the capital was in Kaskaskia and then Vandalia. Today, many tourists visit sites connected to his life. These include the Lincoln Home and the Lincoln Tomb.

Visitors also see the Old State Capitol and his law offices.

During the 19th century, the city's population and politics changed rapidly. Historian Kenneth J. Winkle studied how migration affected local voters. Many people moved in and out of the city during the 1850s. Most residents were short-term visitors who only voted in one or two elections. However, a small group of "persistent" voters stayed and held influence. These people were often wealthier and more highly skilled. They formed a stable core that managed local political affairs. This helped the city remain stable despite frequent population turnover.

The American Civil War turned Springfield into a major center of activity.

Illinois regiments trained in the area, including the first troops under Ulysses S. Grant. Camp Butler opened northeast of the city in August 1861. It served as a training camp and a camp for Confederate prisoners. While businesses grew from the military traffic, some tension existed. Soldiers sometimes caused disorderly outbreaks in the community. After the war ended in 1865, the city became a major hub for the Illinois railroad system. By 1900, the city also became involved in coal mining.

Springfield also features unique architecture and religious history. In 1902, Susan Lawrence Dana commissioned architect Frank Lloyd Wright to build the Dana-Thomas House.

This house was a radical departure from the Victorian style of that time. It used organic designs and featured many art glass panels. The house is a historic site protected by the state for its architectural merit. Additionally, the city became a center for the Lutheran Church–Missouri Synod. The Concordia Theological Seminary moved to Springfield in 1874. This helped serve the spiritual needs of German Lutheran immigrants in the Midwest.

Today, Springfield remains a significant urban center in Central Illinois. The 2020 United States census recorded a population of 114,394 people. This makes it the seventh-most populous city in the state. The larger Springfield metropolitan area has about 208,000 residents. This metropolitan region includes both Sangamon and Menard counties. The city experiences four distinct seasons, typical of middle-latitude locations. From its early days as a frontier settlement to its role as a modern capital, Springfield continues to grow.
