While Berengar's armies were maintaining the situation at the border, Berengar himself was able to thoroughly enjoy the peaceful nature brought about by the stability of his lands. Though several of the other Lords of Tyrol in which he had subjugated in his conquests were primarily upset by the many reforms he had forced upon them, due to his careful deployment of troops in every central region, they had little power to rebel against him.
Most of them, of course, were wise enough not to take such an action while the Bavarians ravaged the rest of Austria. Berengar may be a Tyrant who stripped them of several of their feudal powers, but he provided a stable and economically efficient realm in a time of chaos and destruction. As such, the benefits they gained from Berengar's economic ventures outweighed the disadvantages they gained by surrendering their authority to raise their own troops.
