In November, at the Livadia Palace, near Yalta, Crimea, Mr. Putin unveiled a monument to Russia's Tsar Alexander III, who ruled from 1881 to his death in 1894. The monument is as symbolic as its location. The Livadia Palace had once been the summer residence of the Romanov dynasty — Russia's ruling family. It was also the venue of the 1945 Yalta Conference, where U.S. President Franklin D. Roosevelt, British Prime Minister Winston Churchill and Soviet leader Joseph Stalin decided the fate of post-war Europe. In 2014, Russia annexed the Crimean Peninsula, provoking international condemnation. By unveiling a contemporary monument to a Russian tsar in Crimea, Moscow seeks to signal historical continuities with the peninsula.
