Feb. 28 – On this day in Montana history in 1925 Petroleum County became the final county created from splitting up other counties from the original nine giant counties created by the Territorial Legislature in 1865. It became the 56^th county in Montana. By the 1930s and up until today, many politicians began to argue that the state has too many counties and that consolidation and elimination of some of them would save taxpayer dollars and improve the efficiency of local government and providing services.
