Since Kolomna was a border town, it is likely that one of the Ryazan princes was the prince of Kolomna, but the mention of the rulers of the land is rather meager.

In 1186-1188 the prince of Kolomna was prince Vsevolod Glebovich.

After 1237, information about the Kolomna princes is lost. In 1301, Kolomna was conquered by the Grand Prince of Moscow Daniil Alexandrovich and annexed to the Grand Principality of Moscow. In 1385, Kolomna was captured by the Ryazan Prince Oleg Ivanovich, but a year later she again returned to the Grand Principality of Moscow..

In 1433, Kolomna was singled out as a lot for Basil II Vasilievich Dark, overthrown by Prince Yuri Dmitrievich Zvenigorodsky, who seized the throne of Moscow. However, a few months later, Vasili returned to Moscow. After this, Kolomna was not allocated as anappanage.
