The Provisional Government that replaced the tsar's government in March 1917 faced several major problems. It had to share power with the Petrograd Soviet and was therefore only a temporary "dual government". It did not carry out significant reforms and mainly just abolished the Okhrana secret police and censorship. Continuing the unpopular war further eroded its support. It also failed to address issues like food shortages, fuel shortages, and the land problem in the countryside. As a result, the Provisional Government lost the support of workers and peasants, and its opponents like the Bolsheviks gained popularity by promising to solve these issues.
