Ukaz or Ukase (Russian: указ, pl: указы) in Imperial Russia was a proclamation, edict, or ordinance of the tsar, government, or a religious leader, such as the patriarch of the Orthodox Church of Russia, that had the force of law. Popularly, Ukaz became a term for any official decree, and is generally translated as “decree”.
The term Ukaz came from the verb ukazat, the perfective form of the verb ukazyvat, which has the meaning of to show, announce, or prescribe.
The term was also in use in Soviet Russia and Soviet Union.
In politics of modern Russian Federation, a ukaz has a specific meaning of the presidential decree.
