The political system was reformed as a result of the Finnish general strike of 1905, with the last Diet instituting a new constitutional law to create the modern parliamentary system, ending the political privileges of the estates. The post-independence constitution of 1919 forbade ennoblement, and all tax privileges were abolished in 1920. The privileges of the estates were officially and finally abolished in 1995, although in legal practice, the privileges had long been unenforceable. As in Sweden, the nobility has not been officially abolished and records of nobility are still voluntarily maintained by the Finnish House of Nobility.
