So far: The Camlornian Empire
The Kingdom of Daggerfall was destroyed in a rebellion led by Moric Lothaire, a nobleman from Camlorn. The rebellion occurred in response to the "Camlorn Massacre", in which Daggerfall troops slaughtered twenty citizens who were rioting over a tax increase.
Camlornian (and yes, I may have made that up) press spread the word through the Kingdom and soon, Camlorn, Pharnhelm, and Northpoint united to remove the Gaerings from power and became known as the Camlornian Alliance. Following their declarations of Freedom, the major cities of Farrun and Tehanna joined forces with the Camlornian Alliance.
The troops of Camlorn came up with a song to boost morale and this song would became a chant of every soldier before a battle
"Daggerfall! Daggerfall!
By the dagger ye shall fall!
Tax the poor, kill them too,
We'll return it all to you!"
After a 2 year civil war, the Camlornian Alliance lay siege to Daggerfall which resulted in the final fall of the Kingdom of Daggerfall. Camlorn was awarded the city of Daggerfall after the siege. Shortly thereafter, Camlorn hosted the Conference of Prosperity in which Camlorn, Pharnhelm, Northpoint, Farrun, and Tehanna agreed to the Treaty of Peace which united the cities into one Empire ruled out of Camlorn by Moric Lothaire.
The major cities of Wayrest and Evermor, meanwhile, formed their own alliance to maintain their independence.
(still working on it, obviously)
