rakennemassan
Rakennemassan, also known as the Great Northern War or the Great Northern War, was a significant conflict that took place between 1700 and 1721. The war was primarily fought between Sweden and a coalition of Denmark-Norway, Russia, and Saxony-Poland. The conflict was sparked by Sweden's alliance with France during the War of the Spanish Succession, which led to Denmark-Norway's intervention on Sweden's behalf. The war resulted in Sweden's defeat and the loss of its empire, marking the beginning of Sweden's decline as a major European power. The Treaty of Nystad, signed in 1721, officially ended the war, with Sweden ceding Estonia, Livonia, Ingria, and Karelia to Russia, and ceding Pomerania to Denmark-Norway. The war had significant implications for the balance of power in Europe and the subsequent geopolitical landscape.
