It was called Yama or Yamsky Gorodok, after the Ingrian (ethnic Finnic group) name Jaama. The environs of the town are still cited as the main location of speakers of the nearly extinct Ingrian language. The citadel withstood sieges by the Swedes in 1395 and by the Teutonic Knights during the 1444–1448 war.15-16th centuryThe town became the most important economic center of the Vodskaya pyatina of the Novgorod Republic. There were 201 homesteads in the 15th century in the town; its total population can only be evaluated roughly based on the estimates of three to five persons per homestead. At the end of the Livonian War, it was ceded to Sweden, only to be returned twelve years later, in 1595.
