Note {46} — I. THE GERMANS AND THE EMPIRE TO 1073

The overthrow of Tassilo, duke of Bavaria, is a part of the policy of Karl to reduce the great duchies to control. In order to keep these outlying provinces in subjection and to govern them efficiently Karl divided them into counties over which he placed officials dependent directly upon himself and not upon a duke. This policy was carried out in Alamannia, Aquitaine, and Saxony as well, the purpose being to prevent the formation of independent power in the large divisions of the empire. It was successful under Karl, but later the civil wars among his descendants gave opportunity for the rise of similar great rulers in the same provinces (see nos. 24 and 25).
