The Constitutional Democratic Party, also called Constitutional Democrats and formally the Party of People's Freedom, was a centrist, liberal political party in the Russian Empire that promoted Western constitutional monarchy — among other policies — and attracted a base ranging from moderate conservatives to mild socialists. Party members were called Kadets from the abbreviation K-D of the party name. Konstantin Kavelin's and Boris Chicherin's writings formed the theoretical basis of the party's platform. Historian Pavel Miliukov was the party's leader throughout its existence.
