Aidis

Aidis (also called the Empire of Aidis, the Aidisese Empire, the Imperial Federation of Aidis, and the Senatocracy of Aidis) is a semi-unitary constitutional Senatorial Monarchy. The country is mainly situated in southern Atosan, although some territory lies on other continents, mainly Itholia. The government of Aidis excercises jurisdiction over 10 provinces, 12 imperial colonies, five autonomous regions, and a special self-governing region, called Aidisese Qicui. With over 2.5 billion people, including 1.8 billion citizens, Aidis is the largest country by total area and population.

The Aidisese civilization - one of the world's oldest and longest-surviving - flourished in the Aidisese plains, concentrated around the fertile Ade river. Originally home to hundreds of post-Djakhetian and Meyic tribes - of both nomadic, semi-nomadic, and settled variety - the Aidisese Empire proper was founded c. 2000 AY. Aidis' imperial government was established early on, with both an Emperor and a Senate deriving power through populist means. Through periods of peace and war, and even several military occupations, Aidis remained one of the strongest and most prosperous states on Arteran. During parts of its history, Aidis existed as one of the largest imperial domains in Arteran's history. Despite many changes and upheavals throughout its nearly five thousand year history, the very basic structure of Aidis shifted little. The institution of the Emperor and the Senate still remained, albeit in very different form, for instance.

Today, Aidis is still a major economic power, and while its political power has diminished somewhat, it is still considered one of the great powers. It remains a leading political, economic, and cultural influence in the world.

Etymology
Folk etymology attributes the name Aidis to come from the Aidisese word Ade, meaning "light," and is, meaning "land" or "region." However, from as early as the fifth millennium CE, scholars such as Adeus Nakala have proven this to be an ineffective explanation. A more plausible explanation, also originating from folk etymology, connects "Aidis" with the semi-legendary founders of the empire, Aidos and Aida.
