The Amarr Emperors use life extension procedures that allow them to have long live spans. These extended lifespan of the Amarr noble does not make him immortal, despite the bet efforts of the doctors of the Amarr Empire. The Empire choose a new ruler several centuries ago. Khandi II failed to obtain the throne and should have committed suicide. His desire to live was much stronger than his desire to follow the traditions of the empire.
Khanid II broke away from the Empire and stole two Titans. The Empire he deserted did not react initially, as the new ruler was busy trying to consolidate his rule over the portions of his empire. The enraged Amarr Navy sent a fleet to reconquer the lands held by Khanid, but it managed to recapture only a small portion of the systems controlled by the rebelling nobleman. Khanid II modeled his government after the one that he had willfully deserted. The Kingdom occupies a small portion of space near the fringes of the Empire.
