Nobles

The Nobility is the highest social class in Britannia's aristocracy with the exception of royalty. They possess more acknowledged privileges and higher social status than any other class in Britannian society, with membership thereof typically being hereditary, though there have been cases such as Villetta Nu where a rank is granted for services. The nobility showcase absolute power over everyone that is not gentry, even native Britannians. Most are extremely wealthy, far above most native and Honorary Britannians, though their economic positions are not necessarily inherited of the noble's previous family as evidenced that some nobles are born into nobility while others are awarded titles. The method by which such great wealth is attained isn't specified, though it could be that all nobles have high paying posts, that all nobles receive economic tribute through taxes, or a combination of both. Several powerful noble families have ties with or lead mega corporations such as the Weinberg and Steiner Families with Steiner Konzern. Politically, the nobility are the ones who govern all aspects of the Holy Britannian Empire, though militarily and secretly, it is the Emperor and the Geass Cult who have final say.

After Lelouch vi Britannia ascended the throne, the Britannian aristocracy was abolished, plutocratic cliques were broken up, and the Numbers were liberated. With the exception of the nobility attending court that were Geassed by Lelouch, many nobles attemptted to overthrow Lelouch, only to be quickly vanquished. After Emperor Lelouch destroys the Imperial Mausoleum, a Britannian newscaster quotes a former earl saying that the Mausoleum's destruction was a "childish and violent act."
