This represented the first occasion when two individuals both peaceably held the title dux at any one time in any of the original German provinces.The dukes of Zhringen developed considerable political influence in central Europe before their extinction in the male line in 1218.Aargau was the area which lay south of the river Rhine and the town of Basel in the north, north of the Valais in the south, west of Zurichgau, and east of the Rudolfian kingdom of Burgundy.Its territory was more extensive than the present-day Swiss canton which bears the same name.The Hunfriding were succeeded by the Franconian Konradiner dynasty in 926, when Hermann was appointed duke by Heinrich I King of Germany.
Over the succeeding 150 years, no single family established itself as dukes of Swabia for more than three generations.
Some of these families used their small Swabian bases as a springboard to extend their activities on a broader European scale.
Two obvious examples were the Staufen and Zollern dynasties.
The Swabian nobility constituted a much less cohesive group than the nobility in the neighbouring province of Bavaria.
This was probably due originally to the disparate nature of the Swabian duchy which consisted of three distinct geographical areas: most of what is today the German state of Baden-Wrttemberg, the German-speaking part of Switzerland, and Alsace.
