The subsequent collapse of the Napoleonic Empire resulted in the establishment of a new order in Europe, as well as within the Polish territories, including Konin. The Congress of Vienna, assembled in 1814–1815 to arrange political changes on the continent, awarded Russia the majority of territories formerly held by the Polish–Lithuanian Commonwealth. Konin itself was incorporated into Russia as a part of Congress Poland (formally the "Kingdom of Poland"), a pseudo-autonomous region that was a Russian dependency and which recognized the tzar as its ruler. The town was also designated as the capital of a sector within the Kalisz Governorate; the sector encompassed two counties, Konin County and Pyzdry County. From an administrative standpoint, Konin's sector constituted the westernmost territory of the Russian state.
