Peace of Nystad — Russia Proclaimed an Empire

The Peace of Nystad, signed on 10 September 1721 in the Finnish town of Nystad (now Uusikaupunki), concluded the Great Northern War (1700–1721) and formalised the reordering of Baltic power. Sweden ceded to Russia the provinces of Livonia, Estonia, Ingria, and part of Karelia — the eastern Baltic littoral that controlled the sea approaches to Saint Petersburg — in exchange for Finland and a cash payment of 2 million thalers. The treaty transformed Russia into the dominant Baltic power and, implicitly, a major European state whose influence could no longer be confined to the eastern periphery. Peter celebrated the treaty in Saint Petersburg with three weeks of fireworks and festivities; the Senate voted him the titles 'Father of the Fatherland,' 'Peter the Great,' and 'Emperor of All Russia' — the last title marking the formal elevation of the Russian state from tsardom to empire, a claim that took decades to win full recognition from Western European courts. The emergence of Russia as a great power fundamentally altered the diplomatic calculations of Central and Eastern Europe, contributing to the conditions that would eventually produce the partitions of Poland (1772, 1793, 1795).
