The Ur-Quan Hierarchy, also known as the Hierarchy of Battle Thralls or simply the Hierarchy, is a system created by the Ur-Quan Kzer-Za to manage their series of conquests that perpetuates the Path of Now and Forever. In our region of space, the Hierarchy consists of the races which offered to obey Kzer-Za commands and act as Kzer-Za agents to help subdue other species, and thus keep some degree of political autonomy and freedom to travel through space rather than being confined under a slave shield.
It is unknown how this system has operated in past regions conquered by the Kzer-Za; they did not bring along the ships of any previously conquered races upon attacking our region, though it is possible that at least part of the crew of their Dreadnoughts originates from other regions. Also, the growing instability of our own Hierarchy near the time of the Doctrinal Conflict suggests that it might be dangerous for the Ur-Quan to keep Battle Thralls outside their direct supervision and control.
All species that decline to formally join the Hierarchy as Battle Thralls are relegated to the status of Fallow Slaves and immediately slave-shielded. Fallow species are still required to indirectly serve the Hierarchy by providing resources and labor in the form of Starbases maintained around their planets for the construction, repair, and refueling of Hierarchy vessels. Transport to and from planetary surfaces are performed only under Ur-Quan supervision.
The Kzer-Za have a policy of modifying alien cultures to varying degrees in order to pacify them and make them useful to the Hierarchy after conquest. The extent of this most likely depends highly on the situation; for instance, the Kzer-Za were forced to take radical steps to prevent a nuclear war among the Thraddash — replacing Culture 18 with Culture 19 — while apparently leaving the Yehat clan system intact after both of those species became Battle Thralls. On Earth, they destroyed all Human dwellings, monuments and archaeological sites older than 500 years, including some of which the Humans were not even aware, apparently to forcibly uproot a culture they found troublesome and allow it to be completely replaced with a more Ur-Quan-friendly one. How often this was practiced for conquered worlds is unknown, though the Spathi claim to have undergone a similar process. The Kzer-Za also threaten The Captain with the decimation of Earth should he continue to violate the Oath of Fealty.
