A principality is a part of a kingdom which has the right to select a reigning Prince and Princess by combat. The populace who physically reside within this principality, are subjects of both realms, their principality and their kingdom and are responsible for upholding the laws of both. Realistically, the notion of principality for an area usually grows out of a collective identity, personality, and unity of purpose and activity within the membership of a branch or contiguous group of branches.
Principalities grow and develop naturally over the years.
An area which begins to display a definite trend toward eventual principality status can be encouraged and rewarded by their kingdom by declaring the establishment of a Crown principality. Its only laws are those of the kingdom and its officers are regional deputies to the kingdom officers. However, the special designation as a Crown principality does give it extra emotional reality. The kingdom can allow it to have a champion and develop customs of its own, steps which will ease the eventual transition to full principality. The procedure for creating a Crown principality is under the control of the kingdom, provided the kingdom does not attempt to delegate functions reserved to the royalty and officers of Sovereign principalities.
