History of Sumner County

Early Days in Kansas

For thousands of years, the Great Plains of North America were home to nomadic Native American groups. They moved around to hunt and find food.

From the 1500s to the 1700s, France claimed a lot of land in North America. After a big war called the French and Indian War in 1762, France secretly gave this land to Spain.

In 1802, Spain gave most of the land back to France. But Spain kept about 7,500 square miles.

How Kansas Became Part of the USA

In 1803, the United States bought a huge area of land from France. This was called the Louisiana Purchase. It was 828,000 square miles, and it cost about 2.83 cents per acre. Most of what is now Kansas was part of this purchase.

Later, in 1848, after the Mexican–American War, the Treaty of Guadalupe Hidalgo added more land to the United States. This included parts of southwest Kansas. In 1854, the Kansas Territory was set up. Then, in 1861, Kansas officially became the 34th U.S. state.

Sumner County is Created

Sumner County was officially created on February 26, 1867. It was formed from parts of Marion County and Butler County.

It was named after Charles Sumner. He was a U.S. Senator from Massachusetts. Senator Sumner strongly believed that Kansas should be a free state, meaning it would not allow slavery.

Railroads Arrive

In 1887, the Chicago, Kansas and Nebraska Railway built a train line. It ran north and south from Herington to Caldwell. This line connected many towns, including Wellington in Sumner County.

By 1893, this train line reached all the way to Fort Worth, Texas. Over the years, different railroad companies owned this line. Today, it is part of the Union Pacific Railroad system. Many local people still call it the "Rock Island" line.

Recent Developments

In December 2011, the Kansas Star Casino opened. It is located near Mulvane in Sumner County. It is close to an exit on the Kansas Turnpike.
