After the 1905 Revolution in Russia, the elected representative body that was formed was the State Duma.

State Duma:
- The State Duma was established in 1906 as a result of the October Manifesto issued by Tsar Nicholas II.
- The purpose of the Duma was to serve as a legislative body, representing the various social classes in Russia and providing a platform for the expression of public opinion.
- The Duma consisted of elected representatives from different political parties, including liberals, conservatives, and socialists.

Root of all evils in society according to socialism:
According to socialism, the root of all evils in society is the capitalist system. Socialists believe that capitalism leads to exploitation, inequality, and the concentration of wealth in the hands of a few. Here is an explanation of this viewpoint:

Exploitation:
- Socialists argue that capitalism inherently exploits the working class. They claim that capitalists, who own the means of production, extract surplus value from the labor of workers.
- Workers are paid wages that are lower than the value they produce, with the difference being the profit for capitalists.
- This creates a class divide, with capitalists accumulating wealth and power while workers struggle to make ends meet.

Inequality:
- Socialists contend that capitalism perpetuates inequality in society. The accumulation of wealth by capitalists leads to a concentration of economic and political power.
- This concentration of power allows capitalists to control resources, influence government policies, and maintain their privileged position in society.
- As a result, socialists argue that the gap between the rich and the poor widens, creating social and economic disparities.

Alienation:
- Socialists criticize capitalism for causing alienation among workers. They argue that the division of labor and the pursuit of profit lead to a loss of human connection and fulfillment in work.
- Workers are reduced to being mere cogs in the capitalist machine, performing repetitive tasks without a sense of purpose or control over their own labor.

Conclusion:
In summary, the root of all evils in society according to socialism is the capitalist system. Socialists argue that capitalism leads to exploitation, inequality, and alienation, which perpetuate social and economic injustices. The formation of the State Duma in Russia after the 1905 Revolution marked a significant step towards political representation and the expression of public opinion in the country.
