What do you see as the reasons for the Northern War?

The Great Northern War was a conflict in Europe that lasted from 1700 to 1721. The reasons for this war were the desire of the powers of the Northern Alliance, which included the Russian kingdom, the Danish kingdom and Poland, to weaken the Swedish kingdom. Peter the Great wanted to return Ingermanlandia and Karelia, as well as get access to the Baltic Sea. Saxony wanted to get Livonia. Biographers of the Russian tsar claim that Peter decided to go to war after being humiliated by a cold reception in Riga. It was after this war that the Treaty of Nystadt was signed, which propelled Russia to the leading European powers and made it possible to proclaim the empire, and Peter the emperor.
