Originally Cyrodiil was covered by forest until Emperor Tiber Septim changed it to a more temperate climate. The first recorded inhabitants of Cyrodiil were the Ayleids, a race that is an ancient cousin to the Aldmer. The Aylieds built many structures that still baffle many experts today. The Alyeids used slave labor to build their cities and in 1E 242 there was a slave rebellion which was lead by Imperials. They won the land and it became Imperial land. Cyrodiil became the head of the Imperial Empire and is where the Emperor and Dragonfires reside. And the end of the 3rd Era and early 4th Era the Empire was left with no emperor and Cyrodiil collapsed into many city states.
