Which is the most important reason for why the Tsars rule ended in 1917?

The Tsar took charge of the army in 1915. He appointed his uncle to take command of the Armed Forces. Millions of men were called up into the army leaving know one to look after the farms. As well as being run badly, the army was very poorly equipped because of the shortage of weapons and clothing. Soldiers had no enthusiasm for fighting and had to go battle without weapons. This reflected badly on the Tsar as he was in charge. Soldiers began to desert the army and give up.

Peasants fled to towns to make to make a living making weapons for the war leaving behind their farms. Because of the huge rush into cities and towns there was much fewer farms producing food. Germany had also advanced into Russia taking a great deal of farmland. Prices of food rose dramatically until it was almost 4 times the amount. The lack of transport for food did not help the situation. As the problem developed cities began to starve and riots broke out.

The Tsars rule ended in 1917 because of the huge strikes in Petrograd, however I think that was the collapse of the army was the most important reason forcing the strikes to become bigger causing so much chaos and causing the government to loose control.

The Government were not capable of organizing the war effectively. There was a lot of suffering in the army and 3 million soldiers were lost. When the Russian people realised this they blamed the Tsar and grew even angrier starting larger strikes. They had completely lost faith in their leaders.

In March 1917 the soldiers joined the rioters in Petrograd because they were also angry at the way the war had been managed. Middle classes also joined in the strikes. There was no one left to defend the Tsar so the he was forced to abdicate. A revolution had happened. If the army had not suffered so much, the strikes for food shortages and discontent with the Tsar might not have been at such a great extent.
