What is the historical significance of the Northern War?

The Great Northern War lasted from 1700 to 1721 between the Northern Alliance, which included the Russian Kingdom, Denmark, Saxony and Poland against the Kingdom of Sweden. The Swedish monarch Charles the Twelfth was young and inexperienced. Rivals in the region tried to take advantage of this to weaken Sweden. The result of this war and a historically significant fact was the exit of the Russian state to the Baltic, the receipt of ports and the continuation of the reform by Peter of the state, which from 1721 began to be called the Russian Empire, and the tsar – the emperor.
