Arthan Imperialism (The Old Republic)

Arthan Imperialism is the term which is typically used to describe Emperor Arthus' style of rule after his ascendance to the Imperial throne after the death of Empress Acina. Arthan Imperialism emphasized power ultimately vested in an active Emperor (unlike Vitiate's apathetic rule), a neutered Dark Council that existed only for subservient administration and advisory purposes, incorporation of Aliens into the Empire as full citizens with an increase of social mobility for non-Sith, and the crackdown of backstabbing and cutthroat politics that prevented the Sith Empire from remaining united against the Republic. Because of these changes, some people regarded the Emperor as somewhat liberal, however in reality he was far from it.

Authoritarianism
Arthan Imperialism was very much in line with the Sith ideologies of the past, and the attitudes towards leadership and who ought to rule. Emperor Arthus believed as much as his predecessors did that the right to choose your leaders was a ridiculous notion, and that the best and most fit of the Empire (which would naturally come from the Sith) have a natural right to rule. This type of rule is believed to be more efficient for several reasons, such as the lack of worrying about appeasing the majority in order to win re-election, the lack of an excessive bureaucracy to stifle the necessary response of the head of state to issues affecting the nation, and the lack of bribery of the head of state by corporations (the Emperor is the most wealthy and powerful person in the Empire, what need is there to be corrupt?)

Dark Council
Under Emperor Arthus, the Dark Council functioned much like it did under Empress Acina: as a subservient administration tool and advisory board, rather than the unofficial collective leaders of the Empire who schemed and undermined each other at the detriment of the Empire as a whole under Vitiate.
