The Constitutional Democratic Party (Russian: Конституцио́нно-демократи́ческая па́ртия, romanized: Konstitutsionno-demokraticheskaya partiya, K-D), also called Constitutional Democrats and formally the Party of People's Freedom (Russian: Па́ртия Наро́дной Свобо́ды), was a 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 (or Cadets) from the abbreviation K-D of the party name.
