Ion Mihalache was a Romanian agrarian politician who founded the Peasants' Party in 1918 and led it as well as its successor, the National Peasants' Party. He served as a schoolteacher and lieutenant in the Romanian army. As a politician, Mihalache supported preserving Romania's rural economic base through voluntary farming cooperatives while allowing for some peasant-based industry, taking a left-wing corporatist position. He believed large-scale agricultural enterprises were not necessary for economic success and that dividing land did not necessarily decrease production.
