If I were to go back in time and advise Russian czars on how to avoid the Revolution of 1905, I would suggest a number of different actions they could take.
Firstly, I would advise them to implement more comprehensive and effective land and economic reforms. The vast majority of the Russian population were poor peasants and they were heavily impacted by the lack of land and economic opportunities. By implementing these reforms, the government could have helped to reduce poverty and improve the standard of living for many people, which would have reduced the level of discontent and dissatisfaction with the government.
Secondly, I would recommend the Czars to implement more liberal political reforms, such as granting more civil liberties, rights, and freedoms to the people. This could have included freedom of speech, press, and assembly, which would have allowed people to express their grievances and frustrations with the government more openly and peacefully, which would have reduced the likelihood of violent rebellion.
Finally, I would advise Czars to build a better relationship with the working class and the intelligentsia. Many of the revolutionaries in 1905 came from these groups, and by building a better relationship with them, the government could have reduced their sense of alienation and marginalization and reduced the likelihood of rebellion.
I hope that, by taking these actions, the Czars could have avoided the Revolution of 1905 and prevented the loss of lives and property that resulted from it. Additionally, these actions could have helped to create a more stable and prosperous Russia, which would have benefited all of its citizens.
