Milo S was created in 1966 along with five other military districts as part of a reorganisation of the administrative divisions of the Swedish Armed Forces. It can be seen as the successor of the I Military District (I. militärområdet) created in 1942, but that did not have the same tasks as Milo S. The military district consisted of the land covered by the above-mentioned counties, with the exception of a small part of northern Kalmar County which instead was part of the Eastern Military District (Milo Ö) until 1983 when the whole county's area was incorporated into Milo S. In 1993, the number of military districts of Sweden was decreased to three, and as a consequence of that, Western Military District (Milo V) was merged with Milo S to form a new southern military district. In 2000, these last three military districts were disbanded and the command for the whole of Sweden was placed at the Swedish Armed Forces Headquarters, in accordance with the Defence Act of 2000.
