Death of Friedrich Wilhelm IV in Sanssoci Palace, Potsdam, Germany. He was the King of Prussia during the Revolution of 1848. His conservative politics were one of the factors leading to the revolution. In union with Austria, he saw the Habsburg domination as a natural law of history. In 1849 he was offered the imperial crown by the national assembly in Frankfurt. He refused it, for he felt that only the aristocracy (not an assembly) had the right to offer it.
Wilhelm I becomes the Prussian King. In 1871 he would become the first emperor of the new German Empire.
The 28 nations now at war with the Axis powers pledged that there would be no separate peace made.
