Aristocrat

Aristocrats are high members of society, such as the nobility and upper class.

Sangheili
In Sangheili culture, Aristocrats are those who are skilled enough in the use of Energy Swords to be given personal swords of their own. Once an Aristocrat receives his sword, he is no longer eligible for marriage for ceremonial reasons, but may mate with any female they wish, married or unmarried, in order to pass his "swordsman" genes down to the next generation. This rank applies to all sword wielders, from Special Operation Elites to Councilors. The only stated Aristocrat was Soha 'Rolamee.

Humans
Originally, the term Aristocrat was used to describe the young men of the ruling class in Athens, Greece, who lead their armies with their swords down. It later passed into usage as an alternate word for the "nobility" of the Middle-Ages and is today recognized as the description of a descendant of one of 7,000 families with hereditary titles in Britain and other European countries that still acknowledge hereditary titles. As a Knight and Lord, Fleet Admiral Hood can be considered a human Aristocrat.
