In this way it was hoped the impending dangers would be effectually guarded against. With these objects in view the Grand Cyclops of the Pulaski Den sent out a request to all the dens of which he had knowledge, to appoint delegates to meet in convention at Nashville, Tenn., in the early summer of 1867.[37] At the time appointed this convention was held. Delegates were present from Tennessee, Alabama, and a number of other States. A plan of reorganization, previously prepared, was submitted to this convention and adopted. After the transaction of some further business, the convention adjourned, and the delegates returned home without having attracted any attention. At this convention the territory covered by the Klan was designated as the "Invisible Empire." This was subdivided into "realms" coterminous with the boundaries of States. The "realms" were divided into "dominions," corresponding to Congressional districts; the "dominions" into "provinces" coterminous with counties; and the "provinces" into "dens." To each of these departments officers were assigned. Except in the case of the supreme officer, the duties of each were minutely specified. These officers were: The Grand Wizard of the Invisible Empire and his ten Genii. The powers of this officer were almost autocratic. The Grand Dragon of the Realm and his eight Hydras. The Grand Titan of the Dominion and his six Furies. The Grand Cyclops of the Den and his two Night Hawks. A Grand Monk. A Grand Scribe. A Grand Exchequer. A Grand Turk. A Grand Sentinel. The Genii, Hydras, Furies, Goblins and Night Hawks were staff officers. The gradation and distribution of authority was perfect. But for one source of weakness, the Klan, under this new organization, was one of the most perfectly organized orders that ever existed in the world. As we shall see presently, it was vulnerable and failed because of the character of its methods. Secrecy was at first its strength. It afterwards became its greatest weakness. As long as mystery was conjoined with it, it was strength. When masks and disguises ceased to be mysterious, secrecy was weakness. One of the most important things done by this Nashville convention was to make a positive and emphatic declaration of the principles of the order. It was in the following terms: "We recognize our relations to the United States Government; the supremacy of the Constitution; the constitutional laws thereof; and the union of States thereunder."
