How can you explain the series of military successes of Russia in the Northern War?

The success of the Russian army in the Northern War can be explained by a number of factors.

First, Peter 1 replaced the archers with a regular army. Recruitment for the army has begun in Russia. Of the recruits, 27 regiments were formed.

Secondly, special military educational institutions were opened to train officers.

Thirdly, for the first time in Russia a strong and efficient navy was created.

Fourth, the production of weapons, including cannons, was established. The supply of the army has also improved.

Not the last factor can be called the personal participation of Peter in military operations. The soldiers and sailors fought with enthusiasm and courage, when the sovereign of the Russian state fought shoulder on shoulder with them.
