1. Most industry and banks were nationalised in November 1917. This meant that the government took over ownership and management.
2. Land was declared social property and peasants were allowed to seize the land of the nobility.
3. In cities, Bolsheviks enforced the partition of large houses according to family requirements.
4. They banned the use of the old titles of aristocracy.
