Today in LeFlore County History: Sept. 21

A look at people, places and events connected to Sept. 21 in LeFlore County history.

1830: The Treaty Negotiations at Dancing Rabbit Creek

The very existence and settlement of modern LeFlore County traces directly to the week of September 21, 1830.

• What happened: Representatives of the United States and leaders of the Choctaw Nation—including Chief Greenwood LeFlore (the county’s namesake)—were assembled in Mississippi in the climactic days of negotiating the Treaty of Dancing Rabbit Creek.
• The Impact on the Area: On September 21, the contentious terms outlining land reservations (specifically Article 14) were being drafted and debated before the formal signing days later. Under this treaty, the Choctaw ceded their remaining lands east of the Mississippi in exchange for 11 million acres in Indian Territory—leading directly to the Trail of Tears removals that established the communities, council grounds, and settlements across what is now LeFlore County.

1861: Organization of the 1st Choctaw and Chickasaw Mounted Rifles

During the opening months of the Civil War, the Choctaw and Chickasaw Nations allied with the Confederate States.

• What happened: On September 21, 1861, companies were formally mustered and organized under Douglas H. Cooper and prominent regional leaders (including members of the LeFlore and McCurtain families) into the 1st Choctaw and Chickasaw Mounted Rifles.
• The Impact on the Area: These mounted troops operated throughout the valleys of the Poteau and Arkansas rivers, defending frontier supply lines and participating in area skirmishes, including the lead-up to the Battle of Devil’s Backbone along Backbone Ridge near Pocola.

1898 — Spiro post office established

On Sept. 21, 1898, a post office was established at Spiro in Indian Territory.

At the time, Spiro was located in Skullyville County, part of the Moshulatubbee District of the Choctaw Nation. The community had developed as a railroad station after the Kansas City, Pittsburg and Gulf Railroad reached the area in the 1890s.

The establishment of the post office helped mark Spiro’s development into one of the communities that would become part of present-day LeFlore County.

1922: Heavener’s Municipal Improvement Drive

In late September 1922, as Heavener was emerging as a vital railroad division hub on the Kansas City Southern line, civic leaders enacted major municipal milestones:

• What happened: Reports published on September 21, 1922, documented the town council’s unanimous votes to authorize modernized street improvements and expand utility and sanitation works following a period of post-World War I rail expansion.
• The Impact on the Area: These infrastructure bonds helped pave the way for Heavener’s transformation from a rough-hewn timber and rail camp into an established commercial downtown hub in southern LeFlore County.
