In Finland, this legal division existed until 1906, still drawing on the Swedish constitution of 1772. However, at the start of the 20th century most of the population did not belong to any Estate and had no political representation. A particularly large class were the rent farmers, who did not own the land they cultivated but had to work in the land-owner's farm to pay their rent (unlike Russia, there were no slaves or serfs.) Furthermore, the industrial workers living in the city were not represented by the four-estate system.
