A Peace conference opens in Paris after the Crimean War.

The Congress of Paris was an 1856 diplomatic meeting held in Paris, France, between representatives of the great powers in Europe to make peace almost three years after the Crimean War had started.

The Congress was attended by diplomatic representatives from the nations of France, Great Britain, Russia, Austria, and Prussia, as well as from the Ottoman Empire and Sardinia-Piedmont. The agreement resulted in continued recognition of the Ottoman Empire and the return to pre-war territorial borders for Russia and the Empire.
