Grand Duke of Finland Grand Duke of Finland or the Grand Prince of Finland (Finnish: "Suomen suuriruhtinas" , Swedish: "Storfurste av Finland" ), was from around 1580 to 1809 a title in use by most Swedish monarchs. Between 1809 and 1917, it was the official title of the head of the autonomous Grand Duchy of Finland, who was the Emperor of Russia. The anachronistic female form of the title in English is usually "Grand Princess of Finland" (Swedish: "Storfurstinna av Finland" , Finnish: "Suomen suuriruhtinatar" ). The only women to have used the title were the Swedish Queens regnant Christina and Ulrika Eleonora. A few crown princes of Sweden also were called "Grand Prince of Finland".
