A county seat war is an American phenomenon that occurred mainly in the Old West as it was being settled, although similar incidents elsewhere, such as in southeastern Ohio, have also been recorded.  As new towns sprang up and county lines were drawn, there was intense competition for the status and tax benefits bestowed by becoming a county seat.  These "wars" often involved nothing more than lining up at the ballot box, but sometimes partisans for a particular town would resort to voter fraud, intimidation or violence. The McIntosh County Seat War was a dispute in Oklahoma over the location of the McIntosh County seat that took place between 1907 and 1909.  Following a pair of elections that resulted in the town of Checotah being designated as the new county seat, the people of Eufaula refused to hand over the county records.  As a result, a group of heavily armed men from Chectotah attempted to seize the records, but were forced to surrender during the gunbattle that ensued.  One year later, after another close election, Eufaula became the permanent county seat.
