Incorporation of Königsberg

Date: December 31, 1757 • Location: Moscow, Russia

Empress Elizabeth I of Russia issues her ukase incorporating Königsberg into Russia.

Elizabeth or Elizaveta Petrovna was Empress of Russia from 1741 until her death in 1762. She remains one of the most popular Russian monarchs because of her decision not to execute a single person during her reign, her numerous construction projects, and her strong opposition to Prussian policies. She was the last person on the agnatic line of the Romanovs as her nephew ascended, thus creating the house of Holstein-Gottorp-Romanov.
