Tsarists Russia was a huge country, with a diverse popularity, which made it a difficult country to govern.
In 1900, an overwhelming majority of the population was peasants.
Russia was an autocracy, ruled by a Tsar who was the head of a vast and unresponsive bureaucracy.
The Tsars used repressive measures to keep control but despite this, a number of oppositions parties developed.
The last Tsar, Nicholas II, was an ineffective and weak leader, unable to cope with the pressure of modernising Russia whilst trying to retain autocratic institutions.
The task of modernising Russia was one of that even the ablest leader would have found difficult, as it was so far behind the rest of Europe.
Nicholas received a warning in 1905 when revolution broke out all over Russia. He survived the 1905 revolution by making the move to become more democratic, representative form of government.
WW1 put the Tsar and his regime under tremendous pressure and in February 1917 it collapsed.
