Topeka is the capital city of the U.S. state of Kansas and the county seat and most populous city of Shawnee County. It is situated along the Kansas River in the central part of Shawnee County, located in northeast Kansas, in the Central United States. The population was 122,377 at the 2000 census, and it was estimated to be 122,113 in the year 2006. The Topeka Metropolitan Statistical Area, which includes Shawnee, Jackson, Jefferson, Osage, and Wabaunsee counties, had an estimated population of 226,268 in the year 2003. Three ships of the US Navy have been named USS Topeka in honor of the city. The name "Topeka" comes from a Kansas tribal name meaning "a good place to grow potatoes." (The name "potato" in this case refers to the prairie potato, a perennial herb which was an important food for many Native Americans.) The city, laid out in 1854, was one of the Free-State towns founded by Eastern antislavery men immediately after the passage of the Kansas-Nebraska Bill. In 1857, Topeka was chartered as a city.

In the 1840s, wagon trains made their way west from Independence, Missouri, on a 2,000 miles (3,000 km) journey following what would come to be known as the Oregon Trail. About 60 miles (97 km) west of Kansas City, Missouri, three half Kansas Indian sisters married to the French-Canadian Pappan brothers established a ferry service allowing travelers to cross the Kansas River at what is now Topeka. During the 1840s and into the 1850s, travelers could reliably find a way across the river (and plenty of moonshine) but little else was in the area.

In the early 1850s, traffic along the Oregon Trail was supplemented by trade on a new military road stretching from Fort Leavenworth through "Topeka" to the newly-established Fort Riley. In 1854, after completion of the first cabin, nine men established the "Topeka Town Association." Included among them was Cyrus K. Holliday, an "idea man" who would become mayor of Topeka and founder of the Atchison, Topeka, and Santa Fe Railroad. Soon, steamboats were regularly docking at the Topeka landing, depositing meat, lumber, and flour and returning eastward with potatoes, corn, and wheat. By the late 1860s, Topeka had become a commercial hub providing access to many of the Victorian era's comforts.

After a decade of Bleeding Kansas abolitionist and pro-slavery conflict, the Kansas territory was admitted to the Union in 1861 as the 34th state. Topeka was finally chosen as the capital, with Dr. Charles Robinson as the first governor. In 1862, Cyrus K. Holliday donated a tract of land to the state for the construction of a state capitol. Construction of the Kansas State Capitol began in 1866. It would take 37 years to build the capitol, first the east wing, and then the west wing, and finally the central building, using Kansas limestone.

State officers first used the state capitol in 1869, moving from Constitution Hall - Topeka, what is now 427-429 S. Kansas Avenue. Besides being used as the Kansas statehouse from 1863 to 1869, Constitution Hall is the site where anti-slavery settlers convened in 1855 to write the first of four state constitutions, making it the "Free State Capitol." The National Park Service recognizes Constitution Hall - Topeka as headquarters in the operation of the Lane Trail to Freedom on the National Underground Railroad, the chief slave excape passage and free trade road.

Although the drought of 1860 and the ensuing period of the Civil War slowed the growth of Topeka and the state, Topeka kept pace with the revival and period of growth that Kansas enjoyed from the close of the war in 1865 until 1870. Lincoln College, now Washburn University, was established in 1865 in Topeka by a charter issued by the State of Kansas and the General Association of Congregational Ministers and Churches of Kansas. In 1869, the railway started moving westward from Topeka. General offices and machine shops of the Atchison, Topeka, and Santa Fe Railroad system were established in Topeka in 1878.

During the late 1880s, Topeka passed through a boom period that ended in disaster. There was vast speculation on town lots. The 1889 bubble burst and many investors were ruined. Topeka, however, doubled in population during the period and was able to weather the depressions of the 1890s.

Early in the 20th Century, another kind of boom, this time the automobile industry, took off, and numerous pioneering companies appeared and disappeared. Topeka was not left out. The Smith Automobile Company was founded there in 1902, lasting until 1912.

Home to the first African-American kindergarten west of the Mississippi River, Topeka became the home of Linda Brown, the named plaintiff in Brown v. Board of Education which was the case responsible for eliminating the standard of "separate but equal," and requiring racial integration in American public schools.

It is interesting to note that, at the time the suit was filed, only the elementary schools were segregated in Topeka, and that Topeka High School had been fully integrated since its inception in the late 1890s. It is also interesting to note that Topeka High School was the only public high school in Topeka. Highland Park High School became part of the Topeka school system in 1959 along with the opening of Topeka West High School in 1961. A Catholic high school—Assumption High School, later renamed Capitol Catholic High School, then Hayden High School after its founder, Father Francis Hayden in 1939—also served the city beginning in 1911.

Monroe Elementary, a segregated school that figured in the historic Brown v. Board of Education decision, is now Brown v. Board of Education National Historic Site with interpretive exhibits. The national historic sitewas opened by President George W. Bush on May 17, 2004.

Topeka has struggled with the burden of racial discrimination even after Brown. New lawsuits attempted unsuccessfully to force suburban school districts that ring the city to participate in racial integration with the inner city district. In the late 1980s a group of citizens calling themselves the Task Force to Overcome Racism in Topeka formed to address the problem in a more organized way.

On June 8, 1966, Topeka was struck by an F5 rated tornado, according to the Fujita scale. It started on the southwest side of town, moving northeast, passing over a local landmark named Burnett's Mound. According to a local Indian legend, this mound was thought to protect the city from tornadoes. It went on to rip through the city, hitting the downtown area and Washburn University. Total dollar cost was put at $100 million making it, at the time, one of the costliest tornadoes in American history. Even to this day, with inflation factored in, the Topeka tornado stands as one of the costliest on record. It also helped bring to prominence future CBS and A&E broadcaster Bill Kurtis, who became well known for his televised admonition to "take cover, for God's sake, take cover" on WIBW-TV during the tornado. (The city is, by the way, home of a National Weather Service Forecast Office that serves 23 counties in north-central, northeast, and east-central Kansas).

Like a Phoenix rising from the ashes, Topeka recovered from the 1966 tornado and has sustained steady economic growth. For example, Washburn University, which lost several historic buildings from the tornado, received financial support from the community and alumni to make possible the rebuilding of many school facilities during the coming years. Today, university facilities offer more than one million square feet of modern academic and support space.

In 1974, Forbes Air base closed and more than 10,000 people left Topeka, impacting the city’s growth patterns for years to come. During the 1980’s, Topeka citizens voted to build a new airport and convention center and to change the form of city government. West Ridge Mall opened in 1988 and in 1989 Topeka became a motorsports mecca with the opening of Heartland Park Topeka. The Topeka Performing Arts Center opened in 1991. In the early 1990’s the city experienced business growth with Reser’s Fine Foods locating in Topeka and expansions for Santa Fe and Hill’s Pet Nutrition.

During the 1990’s voters approved bond issues for public school improvements including magnet schools, technology, air conditioning, classrooms, and a sports complex. Voters also approved a quarter-cent sales tax for a new Law Enforcement Center, and then in 1996 approved an extension of the sales tax for the East Topeka Interchange connecting the Oakland Expressway, K-4, I-70, and the Kansas Turnpike. During the 1990’s Shawnee Countians voted to extend tax support to the County for the expansion of the Topeka and Shawnee County Public Library. The Kansas Legislature and Governor also approved legislation to replace the majority of the property tax supporting Washburn University with a countywide sales tax.

In 2000 the citizens again voted to extend the quarter-cent sales tax, this time for the economic development of Topeka and Shawnee County. In August, 2004, Shawnee County citizens voted to repeal the 2000 quarter-cent sales tax and replace it with a 12-year half-cent sales tax designated for economic development, roads, and bridges. Each year the sales tax funds provide $5 million designated for business development job creation incentives, and $9 million for roads and bridges.

Planning is under way to continue to redevelop areas along the Kansas River, which runs west to east through Topeka. In the Kansas River Corridor through the center of town, Downtown Topeka has experienced apartment and condominium loft development, and façade and streetscape improvements. On the other side of the river, Historic North Topeka has benefited from a major streetscape project and the renovated Great Overland Station, regarded as the finest representation of classic railroad architecture in Kansas. The Great Overland Station is directly across the river from the State Capitol, which is undergoing an eight-year, $283 million renovation.

In 2006, construction began to redevelop the historic College Hill district. The district, just north of Washburn University, has been transformed into a vibrant area of retail shops, apartments, and townhomes.
