The great empire of Nerath rose approximately 1500 years ago, encompassing all of the Kendish peninsula and stretching into the continent to the north east.
While the Emporer was human, the empire was able to unite the many races into one egalitarian regime. It broke down the historical isolationism of the races, spreading them throughout the area under Imperial control.
The Empire fell about 500 years ago, which left the civilization it had spread shattered. Cities and towns were left to their own devices.
