It comprised the region between the Rliine and the Lech and part of Switzerland. The office of duke was fre- quently kept in the royal family. In 1079 the duchy passed to the House of Holienstaufen, being bestowed by the Emperor Henry IV. upon Fred- erick of Staufen. Under the rule of this house, which occupied the Imperial throne of Germany from 1138 to 1254, Swabia was the most wealthy and powerful of the German duchies. In 1090 Frederick of Staufen was compelled to give up to Berthold of Ziihringen the Breisgau and the Imperial bailiflship in Zurich. On the extinc- tion of the Hohenstaufen dynasty in 12G8 disin- tegration took place and the ducal vassals (cities, prelates, counts, etc.) claimed independence ex- cept for their allegiance to the emperors. The Count of Wiirttemberg occupied the leading place among the petty rulers. The numerous lesser lords were for the most part obliged to accept the overlordsliip of the House of Ziihrin- gen or of Austria. The cities, of which many had become wealthy and powerful, were striving for local independence. In 1376 some of them formed the first Swabian League, which extended beyond the bounds of Swabia. In 1405 Wiirt- temberg, Baden, and seventeen cities joined to- gether in the League of JIarbach. The two Leagues were of little importance as political powers, but they paved the way for the Great Swabian League, formed in 1488, which und r the leadership of the Count of Wiirttemberg exer- cised administrative and judicial authority over the whole country. During this long period of strife a consideraljle portion of old Swabia had passed into the power of Bavaria. In 1512 Swa- bia became one of the ten circles into which Ger- many was divided for administrative piirjioses by Maximilian I. The dissolution of the Great Swabian League took place in 1533. Among the many citj* commonwealths which arose in Swa- bia were Augsburg, Ulm, and Constance. The southwestern Ciovernment District of Bavaria bears the name of Swabia (or Swabia and New- burg). Its capital is Augsburg. The best gen- eral history is Stiilin, Oesehichte W'Urttemberr/s (Gotha, 1882-87). SWADLINCOTE, swod'lin-kot.
