The Cyrodilic Empire continued to be a force of great power for the first four hundred and thirty years under the rule of the Akaviri Potentates. Though alien to Imperial culture, they established some of the great traditions of Tamriel, granting charters to organizations such as the Fighters Guild and the Mages Guild. Another sign of peace and prosperity occurred in the year 2E 309, when Elsweyr was created by the union of the two Khajiit tribelands, Anequina and Pellitine. But outside of the Empire's borders many conflicting forces drive for the Imperial throne like the Daggerfall Covenant and Aldmeri Dominion. 
When the last Potentate, Savirien-Chorak, was assassinated in 2E 430, leaving no heirs, the great Empire was finally destroyed. Black Marsh forcibly split from the lands of men, as the Knahaten Flu made the land uninhabitable to all but the Argonians themselves. Akavir once again invaded Tamriel, and was barely rebuffed after attacking Morrowind in 2E 572. From one end of the continent to the other, war and rebellion struck at the heart of every great tradition of the land.
The first sign of reunification occurred in the west. The Altmer of Summerset, long concerned with their own wars with other island kingdoms, allied with Valenwood to form the Aldmeri Dominion for their common good. Still greater, however, was the force that rose from the ancient seat of emperors, Cyrodiil. A great general, Talos, liegeless after his lords assassination, began his career as the greatest conqueror in the history of the land. Better known by his Imperial name, Tiber Septim, his armies conquered all of Tamriel, creating the Empire that bears his name even today, and ushering in the Third Era.
