Present - day Springfield was first settled by European Americans in the late 1810s , around the time Illinois became a state . The most famous past resident is Abraham Lincoln , who lived in Springfield from 1837 until 1861 , when he went to the White House as President . Major tourist attractions include a multitude of historic sites connected with Lincoln . The city lies on a mostly flat plain that encompasses much of the surrounding countryside . Hilly terrain lies near the Sangamon River . Lake Springfield , a large artificial lake owned by the City Water , Light & Power company ( CWLP ) , supplies the city with recreation and drinking water . Weather is fairly typical for middle latitude locations , with hot summers and cold winters . Spring and summer weather is like that of most midwestern cities ; severe thunderstorms are common . Tornadoes hit the Springfield area in 1957 and 2006 . The city is governed by a mayor – council form of government . The city proper is also the " Capital Township " governmental entity . In addition , the government of the state of Illinois is also based in Springfield . State government entities located in the city include the Illinois General Assembly , the Illinois Supreme Court and the Office of the Governor of Illinois . There are three public and two private high schools in Springfield . Public schools in Springfield are operated by District No . 186 . The economy of Springfield is marked by government jobs , which account for a large percentage of the city ' s workforce . Early history and the naming of Springfield . Springfield ' s original name was Calhoun , after Senator John C . Calhoun of South Carolina . The land that Springfield now occupies was originally settled by trappers and traders who came to the Sangamon River in 1818 . The settlement ' s first cabin was built in 1820 , by John Kelly . It was located at what is now the northwest corner of Second Street and Jefferson Street . In 1821 , Calhoun became the county seat of Sangamon County due to fertile soil and trading opportunities . Settlers from Kentucky , Virginia , and as far as North Carolina came to the city . By 1832 , Senator Calhoun had fallen out of the favor with the public and the town renamed itself Springfield after Springfield , Massachusetts . At that time , Springfield , Massachusetts was comparable to modern - day " Silicon Valley " — known for industrial innovation , concentrated prosperity , and the celebrated Springfield Armory . Most importantly , it was a city that had built itself up from frontier outpost to national power through ingenuity - an example that the newly named Springfield , Illinois , sought to emulate . Kaskaskia was the first capital of the Illinois Territory from its organization in 1809 , continuing through statehood in 1818 , and through the first year as a state in 1819 . Vandalia was the second state capital of Illinois from 1819 to 1839 . Springfield became the third and current capital of Illinois in 1839 . The designation was largely due to the efforts of Abraham Lincoln and his associates ; nicknamed the " Long Nine " for their combined height of . The Potawatomi Trail of Death passed through here in 1838 . Lincoln . Lincoln and politics . Lincoln arrived in the Springfield area when he was a young man in 1831 , though he would not actually live in the city until 1837 . He spent the ensuing six years in New Salem where he began his legal studies , joined the state militia and was elected to the Illinois General Assembly . In 1837 Lincoln moved to Springfield and spent the next 24 years as a lawyer and politician . Lincoln delivered his Lyceum address in Springfield . His farewell speech when he left for Washington is a classic in American oratory . Winkle ( 1998 ) examines the historiography concerning the development of the Second Party System ( Whigs versus Democrats ) and applies these ideas to the study of Springfield , a strong Whig enclave in a Democratic region , mainly by studying poll books for presidential years . The rise of the Whig Party took place in 1836 in opposition to the presidential candidacy of Martin Van Buren and was consolidated in 1840 . Springfield Whigs tend to validate several expectations of party characteristics as they were largely native - born , either in New England or Kentucky , professional or agricultural in occupation , and devoted to partisan organization . Abraham Lincoln ' s career mirrors the Whigs ' political rise , but by the 1840s Springfield began to fall into Democrat hands , as immigrants changed the city ' s political makeup . By the 1860 presidential election , Lincoln was barely able to win his home city . Population . Winkle ( 1992 ) examines the impact of migration on political participation in Springfield during the 1850s . Widespread migration in the 19th - century United States produced frequent population turnover within Midwestern communities , which influenced patterns of voter turnout and office - holding . Examination of the manuscript census , poll books , and office - holding records reveals the impact of migration on the behavior of 8 , 000 participants in 10 elections in Springfield . Most voters were short - term residents who participated in only one or two elections during the 1850s , and fewer than 1 % of all voters participated in all 10 elections . Instead of producing political instability , however , rapid turnover enhanced the influence of more persistent residents . Migration was selective by age , occupation , wealth , and birthplace . Therefore , more persistent voters were wealthier , more highly skilled , more often native - born , and socially more stable than nonpersisters . Officeholders were particularly persistent and socially and economically advantaged . Persisters represented a small " core community " of economically successful , socially homogeneous , and politically active voters and officeholders who controlled local political affairs while most residents moved in and out of the city . Members of a tightly knit and exclusive " core community , " exemplified by Abraham Lincoln , blunted the potentially disruptive impact of migration on local communities . Business . It has illustrates the important role of the merchant banker in the economic development of central Illinois before the Civil War . Williams began his career as a clerk in frontier stores and saved to begin his own business . Later , in addition to operating retail and wholesale stores , he acted as a local banker and then organized a national bank in Springfield . He was active in railroad promotion and as an agent for farm machinery . Religion . During the mid - 19th century the spiritual needs of German Lutherans in the Midwest were not being tended . As a result of the efforts of such missionaries as Friedrich Wyneken , Wilhelm Loehe , and Wilhelm Sihler , this situation was remedied by the deployment of additional Lutheran ministers , the opening of Lutheran schools , and the creation in Ft . Wayne of the Concordia Seminary in 1846 . The Seminary moved to St . Louis , Missouri , in 1869 , and its practical division moved to Springfield in 1874 . Through this seminary , during the last half of the 19th century and the first half of the 20th , the Lutheran Church Missouri Synod succeeded in serving the spiritual needs of Midwestern congregations by establishing additional seminaries , and by developing a viable synodical tradition . Civil War to 1900 . The American Civil War made Springfield a major center of activity . Illinois regiments trained there , the first ones under Ulysses S . Grant , who marched his soldiers to a remarkable series of victories in 1861 – 62 . The city was a political and financial center of support , and new industries , businesses , and railroads were constructed to help support the war effort . The war ' s first official death was a Springfield resident , Colonel Elmer E . Ellsworth . Camp Butler , seven miles ( 11 km ) northeast of Springfield , Illinois , opened in August 1861 as a training camp for Illinois soldiers , but also served as a camp for Confederate prisoners of war through 1865 . In the beginning , Springfield residents visited the camp to experience the excitement of a military venture , but many reacted sympathetically to mortally wounded and ill prisoners . While the city ' s businesses prospered from camp traffic , drunken behavior and rowdiness on the part of the soldiers stationed there strained relations as neither civil nor military authorities proved able to control disorderly outbreaks . After the war ended in 1865 , Springfield became a major hub in the Illinois railroad system and besides politics and farming , coal mining was a major industry for Springfield by 1900 . 20th century . Utopia . Local poet Vachel Lindsay ' s notions of utopia were expressed in his only novel , " The Golden Book of Springfield " ( 1920 ) , which draws on ideas of anarchistic socialism in projecting the progress of Lindsay ' s hometown toward utopia . The Dana - Thomas House is a Frank Lloyd Wright design built in 1902 – 03 . Wright began work on the house in 1902 . Commissioned by Susan Lawrence Dana , a local patron of the arts and public benefactor , Wright designed a house to harmonize with the owner ' s devotion to the performance of music . Coordinating art glass designs for 250 windows , doors , and panels as well as over 200 light fixtures , Wright enlisted Oak Park artisans . The house is a radical departure from Victorian architectural traditions . Covering , the house contained vaulted ceilings and 16 major spaces . As the nation was changing , so Wright intended this structure to reflect the changes . Creating an organic and natural atmosphere , Wright saw himself as an " architect of democracy " and intended his work to be a monument to America ' s social landscape . It is the only historic site later acquired by the state exclusively because of its architectural merit . The structure was opened to the public as a museum house in September 1990 ; tours are available , 9 : 00 am – 4 pm Wednesdays through Sundays . 1908 race riot . Sparked by the alleged rape of a white woman by a black man and the murder of a white engineer , supposedly also by a black man , in Springfield , and reportedly angered by the high degree of corruption in the city , some white residents took their anxiety and frustration out on blacks . Rioting broke out on August 14 , 1908 and continued for three days in a period of violence known as the Springfield Race Riot . Gangs of white youth and blue - collar workers attacked the predominantly black areas of the city known as the Levee district , where most black businesses were located , and the Badlands , where many black residences stood . Two blacks were lynched and four whites were killed by gunfire when black property - owners sought to defend their homes and businesses . The riot ended when the governor sent in more than 3 , 700 militiamen to patrol the city , but isolated incidents of white violence against blacks continued in Springfield into September . 21st century . On March 12 , 2006 , two F2 tornadoes hit the city , injuring 24 people , damaging hundreds of buildings , and causing $ 150 million in damages . On February 10 , 2007 , then - senator Barack Obama announced his presidential candidacy in Springfield , standing on the grounds of the Old State Capitol .

Lake Springfield is a man - made reservoir owned by City Water , Light & Power , the largest municipally owned utility in Illinois . It was built and filled in 1935 by damming Lick Creek , a tributary of the Sangamon River which flows past Springfield ' s northern outskirts .

It attracts approximately 600 , 000 visitors annually and its of shoreline is home to over 700 lakeside residences and eight public parks . The term " full pool " describes the lake at 560 feet ( 170 . 7 m ) above sea level and indicates the level at which the lake begins to flow over the dam ' s spillway , if no gates are opened .
