With the loss of Miska Khan, the Gospodar seemed to accept the rule of the Norse around Erengrad, while the Talabec Barons still ruled elsewhere. However, after some fifty years of relative peace, the Gospodar rebelled against the Barons, uniting under the leadership of one Alexandr Njevski Khan. Albertus of Brizban writes in The Lost Lands:

Now, rebellions against Imperial authority spread amongst the Gospodar like fire. Kislev lay in the lands of the false Otillian Emperor in Talabheim, Dieter III, who sent an army to fight the uprisings. However, the Gospodar had united under the capable Alexandr Njevski Khan, and they annihilated the Ulrican army of Dieter III. Soon, in the year 1602 IC, Alexandr forced through a treaty with the imposter in Talabheim, which conceded all the demands of the Gospodar that had caused the initial rebellion and appointed Alexandr as Dieter's regent in the lands between the Urskoy and the Lynsk.

Kislevite sources, such as Pitemkin's Kislevan Chronicle and Turgenevych's The History of Kislev, assign even more power to Alexandr Njevski, whom they describe as an independent ruler of Kislev and the equal of Dieter III. According to Pitemkin, Dieter III acknowledged Alexandr as Tsar of Kislev, while in the Talabheim annals, Dieter III appointed one Alexander von Pelzburg as Margrave of Kislev, liege of all Barons, in 1602 IC, with the consent of the Peerhaus. The Kislevite claims are validated by a copy of the original treaty from 1602 IC in the Imperial Library in Kislev, but scholars of The Empire have questioned its authenticity. Much confusion seems to stem from the use of the title Tsar, a Gospodar term unknown to citizens of The Empire at the time. The entry in the Talabheim annals and the treaty in Kislev (if it is authentic) are the first written accounts of the name Kislev for the lands between the Lynsk and the Urskoy.

Kislevite legends now have a line of Gospodar Tsars from Alexandr up until the arrival of the Ungols, which have been included in the Kislevite school of history. However, following the death of Alexandr, there is no further mentioning of a Margrave of Kislev in the Talabheim annals, and the Sigmarite school only mention the following Tsars as a piece of folklore, if at all. In general, Imperial sources are so caught up in the turmoil of the rival Emperors of this era that little was written on the events of this remote corner of the Old World.

From the accounts of the Taalite monks it seems clear that by the time of Alexandr Njevski the Gospodar had given up their former nomadic life style, replacing their herds with a fairly advanced agricultural production.

The Invasion of the Ungols

In 1750 IC, a great horde of the Ungols crossed the World's Edge Mountains, the very tribe that some three centuries before had pushed the Gospodar east. The capable Ungol horse warriors charged all over Kislev and across the Urskoy into eastern Talabecland. In the north, the Norse warriors drove them back, but the rest of Kislev fell to the Ungols, as did the eastern parts of Talabecland which is now the League of Ostermark. In the words of Albertus of Brizban:

These were years of utter tragedy. Wild hordes of barbaric Ungols from the East invaded the land and peoples of Sigmar. The Empire was weak, as the false Ulrican Emperors in Middenheim and Talabheim did their best to tear down the realm that Lord Sigmar himself had built, and brave successors such as St Sigismund II had strengthened. The Ottilian imposter in Talabheim, Helmut II, had neither the courage nor the strength to face the invaders, and a humiliating treaty was concluded in Pelzburg in 1751 IC. It installed the supreme Ungol leader, the infamous Dengis Khan, as ruler of Kislev, vassal of the Talabheim Emperor only in name. Thus, another giant step had been taken towards this tragic loss of Sigmarite land.

The divide in the Kislevite school is most drastic in their descriptions of the Ungols. Norse writers describe them as brutal and unlawful invaders, while the Gospodar usually regard them as one of the Kislevite tribes joining their brothers in the new kingdom. Thus, Pitemkin writes:

As the Kislevites celebrated the 250 year anniversary of the foundation of their Kingdom, the lost tribe of the Ungols finally arrived in the West. They united with their Kislevite brothers, and the brave Ungols cleansed the Kingdom of the Barons from The Empire who had gained ground since the glorious days of Tsar Alexandr Njevski. A huge tribal council was called in Pelzburg and the Kislevite Tsar Alexandr IV generously offered the throne to the mighty Dengis Khan of the Ungol tribe. In honour of the new Tsar, they renamed Pelzburg as Dorogo. Within a year, the new Tsar of Kislev had entered into a new treaty with Emperor Helmut II in Talabheim which reaffirmed all the rights that had originally been bestowed upon Tsar Alexandr.

Sigmarite scholars hold this view in strong contempt, and in this case they seem right to do so. There are few indications that the Gospodar played any active role in the Ungol overthrow of the Talabec Barons, and there is neither mention of Alexandr IV nor any reference to the 1602 treaty in the treaty of 1751 IC. As an aside, Dorogo seems to be derived from the Ungol tongue, its meaning lost today.

The Ungols established themselves as a military ruling class in central and southern Kislev, alongside some of the Talabec Barons, who acknowledged the supremacy of the Khan. The Gospodar remained the farming lower class, they had turned into under the Barons from The Empire. The Ungols seem to have had few strong religious beliefs, and readily accepted the worship of Taal and Rhya that had gained a strong following amongst the Gospodar. In 1900 IC, Uttila Khan mustered his army and led a military campaign all the way to the gate to Talabheim. Albertus of Brizban reports:

The long way to disaster had come to an end. The imposter in Talabec, the self-proclaimed Emperor Gregory Dissell, was left with little choice when he found himself caught as a mouse in his hole, with Ungol hordes surrounding Talabheim. Thus, Gregory shamefully signed the treaty that gave the Ungol ruler, Uttila Khan, sovereignty over all land east of Talabheim. Finally, the land of Sigmar had been given away, not a single arm raised to defend it.
