Why were the russian people unhappy with their country’s involvement in world war l ?

Russians were generally unhappy with their government. The poor perfomance of the Russian army in the war catalysed this bitter feeling.

High levels of death and a devastating economy.

Russia was sending millions of untrained soldiers to the war with not enough supplies which led to a very high death count in Russia. Nicholas II spent much of Russia's money on the war leaving the rest of the country in poverty.
