The Springtime of Nations (28 March 1854)

Historical Map of Europe

In 1853, Russia occupied the Ottoman vassal states of Moldavia and Wallachia. After the Russians refused an ultimatum to withdraw, the Turks declared war, but quickly lost control of the Black Sea when the Russians defeated their navy at Sinop. Unable to accept Russian dominance over the Ottoman Empire, France and Britain formed an alliance and entered the war a few months later.
