Pottawatomie County was carved out of land originally given to the Creek and Seminole after their forced removal from Georgia and Florida. After the Civil War, the Creek and Seminole were forced to cede their lands back to the federal government, and the area of Pottawatomie County was used to resettle the Iowa, Sac and Fox, Absentee Shawnee, Potawatomi and Kickapoo tribes. Non-Indian settlement began on September 22, 1891 when all the tribes except the Kickapoo agreed to land allotment, where communal reservation land was divided and allotted to individual members of the tribes. The remaining land was opened to settlement. During the land run, Pottawatomie County was organized as County "B" with Tecumseh as the county seat. In 1892, the voters of the county elected to rename County "B" as Pottawatomie County after the Potawatomi Indians. In 1895, the Kickapoo gave up their land rights and their land was given away to white settlers in the last land run in Oklahoma. In 1930, Shawnee, now bigger in size than Tecumseh, was approved by the voters to become the new county seat. The Pottawatomie County Court House was built in 1934 by the Public Works Administration. The court house project cost $250,000.00 to complete. On May 19, 2013, during an outbreak of tornadoes, a mobile home park was nearly destroyed killing a 79-year-old man and injuring at least 6 others as well as damaging at least 35 structures. Frame and brick homes west of Shawnee were also affected.
