Kozlov

Kozlov was a small fortified town on the Zhizhala east of Vyazma, in the lands contested by Lithuania and Moscow. Its district belonged to princes of the Kozlovsky family. A treaty of 1494 names one branch among Moscow's subjects, while descendants of another remained in Lithuanian service and retained claims to the district. The town's history reflects the divided loyalties of frontier princes as the balance of power shifted across the Smolensk lands.
