Landscape & places

Tallgrass Prairie National Preserve protects part of the Flint Hills. Much of North America’s tallgrass prairie was converted to farms and towns; the preserve shows the grassland ecosystem that once covered a much wider area.

03

Land and water

The total area includes 211,754 km² of land and 1,346 km² of water, according to Census area measurements.

How the landscape works

The Flint Hills preserve helps explain the difference between a remnant ecosystem and a landscape that was always rare. Tallgrass prairie once covered a much wider area. A protected remnant gives evidence of that larger past distribution. Grassland is an ecosystem with interacting plants, animals, soils, and disturbance, not simply land waiting to become a farm.

History

Why Kansas became a battleground over slavery

The Kansas–Nebraska Act of 1854 removed the existing restriction on slavery in the area and allowed settlers to decide whether slavery would be permitted. Because control of territorial government could influence that decision, proslavery and antislavery groups competed to bring supporters into Kansas and win elections.

Election fraud, rival governments and armed attacks followed. The period became known as Bleeding Kansas. The conflict included attacks on antislavery Lawrence and killings by John Brown’s group at Pottawatomie Creek. Kansas finally entered the Union as a free state on January 29, 1861. Popular sovereignty had shifted the fight into the territory rather than resolving it peacefully.

Why this mattered

Popular sovereignty meant allowing settlers to decide whether slavery would be permitted. That policy did not remove the conflict over slavery; it moved the struggle into the territories. Proslavery and antislavery groups competed to influence Kansas’s political future, and violence followed. A procedure presented as a solution can intensify conflict when the underlying issue remains unresolved.

People and place

Indigenous history and communities today

The Prairie Band Potawatomi Nation provides a present-day tribal perspective from Kansas. The territorial conflict over slavery is important, but it is not a complete account of the peoples whose lives and lands are part of the state.

Economy

Main activities

In 2025, manufacturing was the largest of the broad industry groups compared here by current-dollar output. Other major groups included real estate and rental and leasing, government and government enterprises, and professional and business services.

Total economic output was $241.4 billion in current dollars in 2025.

Production, jobs and wages answer different questions

The industry chart measures the value of production. It does not count workers. An industry with a large share of GDP need not employ the most people or pay the highest wages. Employment and wage data would be needed to answer those questions.

Read the trend, then ask what explains it

Kansas’s population increased by about 1.3% between 2020 and 2025 in this series. That shows the size of the change. The chart alone cannot tell us how much came from births, deaths or migration.

Real GDP adjusts for changes in prices, so it helps compare production over time. Current-dollar GDP includes price changes. Neither measure tells us how income is distributed among residents.
