Short tenures

At the time Edigi was the Chief with the power to elect or depose kings in Tartary. From The Bondage and Travels of Johann Schiltberger, a Bavarian who at the time was a slave of Zeggra:

Then Edigi elected a king named Polet, who reigned one year and a half.

Then there was one named Segelalladin, who expelled Polet;

and after this, Polet’s brother was king, and he reigned fourteen months.

Then came his brother, named Thebachk, who fought with him for the kingdom, and killed him, and then there was no king.

But he had a brother called Kerumberdin, who became king, and reigned five months.

Then came his brother Theback, and he expelled Kerimberdin and became king.

Then came Edigi and my lord Zeggra, and they drove away the king, and Edigi made my lord the king as he had promised. He was king for nine months.

Then came one named Machmet, and he fought with Zeggra and with Edigi. Zeggra fled to a country called Distihipschach, and Machmet became king.

Then came one named Waroch; he expelled Machmet and became king.

After that, Machmet recovered, and he drove away Waroch and was again king.

Then came one named Doblabardi, who drove away Machmet and became king, and was king for three days only.

Then came the same Warach, who expelled Doblabardi, and again became king.

Then came my lord Machmet, and he overcame Waroch and again became king. After that, came my lord Zeggra, and he fought with Machmet and was killed.
