The Tsar of Russia became unpopular because of his cruel and harshly rule. He increase the taxes for the people. And the French Revolution had brought a drastic change to the society and thus Tsar became unpopular.

The Tsar of Russia, Nicholas II, became increasingly unpopular during the First World War due to a combination of military failures, economic hardships, and his autocratic ruling style. Here are the key reasons why he lost support and faced growing discontent among the Russian people:

Military Failures:
- In the early stages of the war, Russia suffered several major military defeats against Germany and Austria-Hungary, leading to the loss of significant territories and casualties.
- The lack of effective leadership and outdated military strategies resulted in heavy losses and undermined the morale of the Russian soldiers.
- The Tsar's decision to personally take command of the Russian army further worsened the situation as his lack of military experience and poor decision-making contributed to the military failures.

Economic Hardships:
- The war put a strain on the Russian economy, leading to inflation, shortages of essential goods, and rising food prices.
- The government's inability to address these economic challenges exacerbated the suffering of the Russian people, particularly the working class and peasants who faced extreme poverty and hunger.
- The Tsar's refusal to share power or listen to the demands of the people further contributed to the growing discontent.

Autocratic Ruling Style:
- Nicholas II was an absolute monarch who ruled with little regard for democratic principles or the needs of the people.
- He resisted political reforms and limited the power of the Duma (the Russian parliament), leading to a lack of representation and a sense of exclusion among the population.
- The Tsar's wife, Empress Alexandra, was of German descent, and her influence on government affairs further fueled suspicions and rumors of German sympathies, undermining the Tsar's credibility.

Growing Unrest and Opposition:
- As the war dragged on and the hardships intensified, opposition to the Tsar's rule grew. Strikes, protests, and riots erupted across the country, demanding an end to the war and improved living conditions.
- Political groups, such as the Bolsheviks led by Vladimir Lenin, capitalized on the discontent and gained support by promising radical change and an end to the monarchy.
- The Tsar's decision to personally take command of the army also created a power vacuum in the capital, allowing political unrest to escalate and further destabilize the government.

In conclusion, the Tsar of Russia became unpopular during the First World War due to his military failures, economic hardships, autocratic ruling style, and the growing opposition and unrest among the Russian population. These factors ultimately contributed to the downfall of the Romanov dynasty and the Russian Revolution of 1917.
