The area of the Unna district belonged to the earldom Mark, which after its end changed to belong to Prussia. In 1753 its organization was reformed and the first Hamm district was created. During the napoleonic times it was part of the ruhr departement, but afterwards Prussia the district was recreated, however with several changes. In 1901 the city Hamm left the district to become district-free city, however the administration of the district stayed in Hamm until 1929. Together with the move of the administration the district also changed its name to reflect the new center Unna. Later reorganization changed the district further, the last one in 1975 finally added the cities Lünen, Schwerte, Selm and Werne to form today's district.
