Tsardom of Russia.

The Tsardom of Russia was the Russian was the name of the centralized Russian state that was formed by Ivan IV. It was formed in 1547, It lasted until 1721 when it was proclaimed the Russian Empire. After it was proclaimed The Russian Empire it was also considered a European Country based on it's masses of land now overflowing into Europe. The government of the Tsardom of Russia was of course Tsar's. The two Tsars of Russia that lasted in the Tsardom Era were Ivan IV and Peter I. I would go into more depth about this time but It is quite a complicated era with a lot of problems and wars so I will just sum up some of the main events of the era.
I will start off with the Time of troubles(1598–1613). This was a period of which around a third of the population died from lack of food. This is often considered the start of the revolution because of the masses of unrest caused by it. This is considered one of the down points in Russian history of late. My other key event will be the Treaty of Nystad(10 September 1721).  This is the point in time where Russian invaded large parts of Sweden and a treaty was formed so that Sweden could still exist while Russia still controlled a large part of Sweden. This could be linked to unrest in Russia from the larger amount of land and also the immigrants.
