Sigismund II, known more commonly as Sigismund the Conqueror reigned as Emperor of the Empire of Man from 479 IC to 505 IC. The ascension of the Reiklander Elector Sigismund to the Imperial throne was marked by the people of Reikdorf with celebration. In recognition of its importance, Emperor Sigismund II renamed the city of Reikdorf into Altdorf and re-instituted the Imperial Government to the capital of the Reikland. During his reign as Emperor, Sigismund had embarked on a grand building program within the confines of his capital city, but his real achievements during this age of conquest and prosperity was his participation in a period Imperial historians call "the Drive to the Frontiers".
