Early history

For many millennia, the Great Plains of North America was inhabited by nomadic Native Americans. From the 16th century to 18th century, the Kingdom of France claimed ownership of large parts of North America. In 1762, after the French and Indian War, France secretly ceded New France to Spain, per the Treaty of Fontainebleau.

19th century

In 1802, Spain returned most of the land to France. In 1803, most of the land for modern day Kansas was acquired by the United States from France as part of the 828,000 square mile Louisiana Purchase for 2.83 cents per acre.

In 1854, the Kansas Territory was organized, then in 1861 Kansas became the 34th U.S. state. In 1860, Saline County was established within the Kansas Territory, which included the land for modern day Gypsum.

The community was founded as a Templer community called Tempelfeld.^[4] Gypsum was named after Gypsum Creek.^[5] The Gypsum post office has operated under that name since 1886.^[6]
