Kostroma is one of the most ancient cities in Russia, with a history closely interwoven with the key events of the state's formation. Its past is rich in significant milestones, from princely internal conflicts to the rise of a new ruling dynasty.
Foundation and first mentions. The official founding date of Kostroma is considered to be 1152, an event linked to the activities of Prince Yuri Dolgorukiy, who was strengthening the borders of the Rostov-Suzdal Principality. Although this date was proposed by historian V. N. Tatishchev and lacks direct chronicle confirmation, archaeological findings also point to the existence of a settlement in the mid-12th century. The first reliable mention of the city in chronicles dates back to 1213 in connection with princely feuds, when Kostroma was burned by Prince Konstantin of Rostov.
Key factors in the formation of Kostroma were its geographical location, trade, and political role. The city was founded as a fortress in a strategically important place — at the confluence of the Volga and Kostroma rivers, which allowed for control over busy trade routes. Thanks to its location on the Volga transit route, Kostroma grew rapidly economically and by the 17th century became the country's third-largest craft and trade centre after Moscow and Yaroslavl. The city acquired special significance when it became the capital of the independent appanage Kostroma Principality in 1246, and later, during the Time of Troubles, the "cradle" of the Romanov dynasty. It was here, at the Ipatiev Monastery in 1613, that Mikhail Romanov was called to the throne.
Early cultural and economic features of the city are closely tied to craftsmanship. By the 17th century, textile (especially linen), leather, soap-making, and jewellery industries were flourishing here. Later, in the 18th century, Kostroma became Russia's leader in the volume of linen fabric production. Powerful fortress-monasteries were erected around the city, such as the Ipatiev and Nikolo-Babaevsky monasteries, which served not only as spiritual centres but also as important defensive structures.
