Kurmysh was founded in 1372 when Prince Boris Konstantinovich of Nizhny Novgorod-Suzdal ordered its establishment on the Sura River ("постави город на Суре Курмыш нарече").[5] It was the easternmost Russian settlement for almost two centuries and it helped to consolidate Russian influence in the Volga region.[5] As a result, it bore the brunt of attacks from the east.[5]
In 1406–1407, Grand Prince Vasily I of Moscow, bequeathed "Kurmysh with everything that came with it" to his son.[5] In 1445, Vasily II was released from Kurmysh after being captured by Ulugh Muhammad of the Kazan Khanate and forced to pay a ransom.[5]
Following the capture of Kazan in 1552 by Ivan the Terrible, Kurmysh's position declined as the Russian fortress of Alatyr was established to the south.[5] From the 1560s, it served as the administrative center of Kurmyshsky Uyezd within the Russian tsardom until 1708.[4] In the second half of the 16th century and in the 17th century, it was mainly made up of service class people.[4]
Kurmysh further lost its significance when the majority of the service class people were transferred to the border near Simbirsk.[4] The lower categories of service class people, including Cossacks and streltsy, became state peasants in the early 18th century.[4] By 1804, it had a population of 695.[4] According to the 1897 census, about 3,200 people lived there.[4]
