The only planets which escaped the destruction of their governments were those few anarchical states which had no governments in the first place. But for other populations the effect was to reduce the cohesion and organization of their social fabric to a level below that of the anarchistic worlds. For most, the Butlerian Jihad meant anarchy without any preparation for that state. More billions died after the Jihad. Under such conditions, the rise of military and economic entrepreneurs was inevitable. A complete breakdown of all facets of social structure created a void into which personal relationships m&ved, and when personal ties replaced the normal workings of a state in such matters as military organization, taxation and legal systems, feudalism emerged. This form of government has historically arisen when no state is strong enough to maintain order and protect the weak against the strong. Most of the feudal, powers began as economic or military units but, with a very few exceptions, those that lasted became a combination of both. Such exceptions as the Sardaukar, who depended for their power upon simple force majettr. or the planet of Dendros, whose enormous forests provided a continuing source of wealth for some few million militarily unorganized citizens, were very rare; indeed, die Sardaukar were unique. In the normal case, successful feudal powers, especially those that managed to gain control of a planet, based their power upon a combination of dominance of die world's economy and control of its military forces, Some worlds managed to escape subjection by a feudal power, whether foreign or home grown. Two of the most famous are Tupile and Tleilax. but they were permitted to survive as non-feudal only because they rendered the Imperium some special service which demanded that they remain outside the Imperium, The Tteilaxu provided that forbidden commodity, technology, while the Tupile entente provided a refuge for defeated Houses, Without such a refuge, such Houses would have been destroyed. The House Comno lasted as long as it did by avoiding such extremes whenever possible. Feudal states are imperialistic insofar as their power and their opponents will permit, and these new governments were no exception. The wealthier or more militarily powerful expanded their boundaries as swiftly as they could, and the weaker soon fell prey to the strong. There were certain limits upon this expansion, though. For a time the possibility of interstellar empire was gone with the machines that had been the object of the Butlerian Jihad.
