Yazhelbitsy
Yazhelbitsy is a village ( selo) in Valdaysky District of Novgorod Oblast, Russia, located on the M 10 highway south-east of Veliky Novgorod.
It is probably most famous as the site of the 1456 Treaty of Yazhelbitsy between Grand Prince Vasily II (r. 1425-1462) and Novgorod the Great, in which Novgorod's political independence was strictly curtailed. Failure to abide by the treaty led to Novgorod's defeat at Shelon River in 1471 and its final subjugation by Moscow in 1478.
