The history of the city of Gagarin (which bore the name Gzhatsk until 1968) is inextricably linked to the era of Peter the Great's reforms. Its appearance on the map was the result of the strategic vision of Emperor Peter I. In the early 18th century, the new capital, St. Petersburg, required a steady supply of food from the central provinces. Recognizing the navigable potential of the Gzhat River, the sovereign ordered the establishment of a transit point here. The official starting point of the city's history is considered to be the decree of 1719 regarding the opening of the Gzhatsk Pier, which began the regular movement of grain barges toward the Baltic.
Several factors contributed to the rapid transformation of the river pier into a wealthy trading center. Chief among them was its favorable geographical position on the waterway connecting the Volga basin with the Baltic Sea via the Vyshny Volochyok system. Furthermore, development was bolstered by state policy: by order of the Tsar, wealthy merchants and craftsmen from other cities were resettled here, ensuring a rapid influx of capital. The fertile lands surrounding the area yielded bountiful harvests, making grain the primary export commodity.
Thanks to successful commerce, the settlement flourished. In 1776, Empress Catherine II granted Gzhatsk Sloboda the status of a district town and approved its coat of arms: a barge loaded with grain on a silver field. This image symbolized the city's key role as the "breadbasket" for St. Petersburg. Gzhatsk developed as a typical merchant city with sturdy stone buildings; local patrons actively built churches and public buildings, some of which have survived to this day, creating the historical character of modern Gagarin.
