"The Cold War stemmed from war, from the violence, fear and paranoia that conflict fostered, and from defeat and victory in two successive struggles, World War One and the Russian Civil War. Defeat at the hands of Germany and, even more, the social and political strain of conflict on an unprecedented scale in World War One (1914–18) led, in March 1917, to the fall of the Romanov dynasty in Russia and its replacement by a provisional, republican government. The dynasty had responded more successfully to the challenge of the Thirteen Years’ War with Poland in 1654–67, to the Great Northern War with Sweden in 1700–21, to wars with the Turks, Sweden and France between 1806 and 1815, and even to the brief French occupation of Moscow in 1812, than it was to do to war of a very different type with Germany."
