The war of 1809 split up Sweden into two states and it lost Finland to Russia. The Grand Duchy of Finland received its own House of Nobility in 1818. The Swedish noble families who had chosen to remain in Finland were registered, and the Czar-Grand Duke continued to raise deserving Finnish citizens to the nobility.
The main task of the House of Nobility today is to take care of the palace of the nobility and its collections and to keep personal data of all Finnish noblemen from the Middle Ages onwards. It also publishes the Pedigree Book, which comprises data of all living members of the nobility.
