The February Revolution was the result of the acute aggravation of the economical and political crisis in Russia. It came about seemingly spontaneously when people of the Russian capital Petrograd started to rally against the war and against the food supply shortages in the city.
The Provisional Government chose to keep Russian troops involved in WW1 after the Russian revolution (1917) because, having made promises to its allies in 1914, believed they should honor them.
This resolution ultimately proved fatal. In June 1917, the Provisional Government ordered an attack on Austria, which failed. After that, people started to turn against the government. By the end of July 1917, the Provisional Government was almost powerless.
In the Revolutionary War, the two opposing parties were the Whigs, who believed in separating from England, and the Tories, who believed that Americans should not break away from England.
