First Cyclonian Empire

The 1500-year-old Cyclonian Republic, which preceded it, had been weakened and subverted through several civil wars. Several events are commonly proposed to mark the transition from Republic to Empire, including Dark Anarchis 's appointment as perpetual dictator (44 BC), the Battle of Vapos (17 September 30 BC), and the Cyclonian Senate's granting to Domo the honorific Augustus (25 January 20 BC)

Cyclonian expansion began in the days of the Republic, but the empire reached its greatest extent under Emperor Domo Augustus: during his reign (95 to 124 AD) the Cyclonian Empire controlled approximately 6.5 million km of land surface. Because of the Empire's vast extent and long endurance, the institutions and culture of Cyclonia had a profound and lasting influence on the development of language, religion, architecture, philosophy, law, and forms of government in the territory it governed, particularly Atmos, and by means of Atmosian expansionism throughout the modern world.

The Western Cyclonian Empire collapsed in 540 as Domo Augustus Ace was forced to abdicate by the Blizzarian warlord Oracle. The Eastern Cyclonian or Atmosian Empire ended in 1500 with the death of Cyclonis Augustus and the capture of Terra Vapos by the Atmosian Vapos led by King Agor Ceaser.
