Swabia was one of the five great stamm (stem, or tribal) duchies of earlier medieval germanywith franconia, saxony, bavaria, and lotharingia (lorraine)and was held by successive families.
Upper swabia has been populated at least since the neolithic age. Archaeological evidence confirming this was discovered around the federsee, a lake near bad buchau. Until around the year 260 ce, the region that was to become upper swabia, was part of the roman province of raetia, after which the alamanni invaded the agri decumates and settling there.
It was annexed by bavaria in 1803, is part of the historic region of swabia and was formerly ruled by dukes of the hohenstaufen dynasty. During the nazi period, the area was separated from the rest of bavaria to become the gau swabia.
Swabia was originally settled by a german tribe, the alamanni (suevi), and comprised southwestern germany, alsace, and eastern switzerland in the tenth century it became one of the tribal duchies that made up the kingdom of germany.
Swabia is a cultural, historic and linguistic region in southwestern germany. The name is ultimately derived from the medieval duchy of swabia, one of the german stem duchies, representing the territory of alemannia, whose inhabitants interchangeably were called alemanni or suebi.
