Final answer:
The provisional government in Russia after the Czar abdicated was not popular due to its perceived weakness and lack of representation for the majority of the population. It was eventually overthrown by the Bolsheviks.
Step-by-step explanation:
The provisional government that took over after the Czar abdicated in Russia was not popular for several reasons. First, the government was seen as weak and ineffective in addressing the needs of the people. It was unable to provide food and relief to the hungry population and failed to end Russia's involvement in World War I, which resulted in continued suffering for the people. Second, the provisional government was dominated by middle-class politicians and did not represent the interests of the majority of the Russian population, including workers and peasants. This lack of popular support undermined the government's legitimacy.
Eventually, the provisional government was overthrown by the Bolsheviks, a group of revolutionaries led by Vladimir Lenin. The Bolsheviks promised to end the war and address the grievances of the workers and peasants. Their message resonated with the majority of the Russian population, leading to the overthrow of the provisional government and the establishment of a communist state.
