Day County was one of the original counties of Oklahoma Territory. Day County was in the western part of the territory, along the Texas border. When it was originally established in 1890, it was known as E County. It was later named for Charles Day, the contractor who built the first courthouse in the county seat, the now-defunct town of Ioland, Oklahoma.
The community of Ioland was named as the temporary county seat when County E was first established in 1890, but this location proved unsatisfactory for several reasons. First, the water tasted bad, and no better source was available. Second, Ioland was not a convenient location for the majority of county residents, who lived on the other side of the Canadian River. Third, the temporary courthouse at Ioland mysteriously burned down during the night of November 12, 1893. The dayafter the fire, the three county commissioners ordered that the county seat be reestablished at Grand. The county commissioners voted to move the seat to Grand, Oklahoma, along the banks of the Canadian River, which ran through the middle of the county.
"Free Grass" ''vs''. "Herd Law"
The burning political issue in Day County was the question whether land should be free-range or whether the movement of cattle should be restricted. Most of the large cattle ranches had started when the land was still controlled by Texas. However, Texas law did not apply when the U. S. created Oklahoma Territory. Most of the settlers who moved in during the territorial days were small farmers. Initially, the cattlemen had the political advantage. If a farmer found that free-range cattle had eaten his crops, he had no recourse to be compensated for his loss. As a result, there were many charge by cattlemen that some farmers had put poison in the waters where cattle drank. The Arapaho Bee reported on May 17, 1901 that a posse of cattlemen lynched a resident of Ioland, after he had been accused of poisoning roaming cattle.
Dissolution of county
When Oklahoma was granted statehood, effective November 16, 1907, Day County was abolished and several county lines were redrawn. Among the changes were Day County being split along the Canadian River. The section of the county north of the river became part of Ellis County, while the area south of the river is now northern Roger Mills County. Also, a narrow strip of land in the northeast of the old county now falls within the boundaries of Woodward County. Grand, now a defunct town, served as county seat of Roger Mills County until a 1908 election moved that function to the town of Arnett. Grand's townsite is south of Arnett. Most of the inhabitants moved away by 1914. No remains are visible at the townsite.
Geography
Day County encompassed the Antelope Hills, a historical landmark.
