Nicholas II or Nikolai II, known as Saint Nicholas in the Russian Orthodox Church, was the last Emperor of Russia, ruling from 1 November 1894 until his forced abdication on 15 March 1917. His reign saw the fall of the Russian Empire from one of the foremost great powers of the world to economic and military collapse. He was given the nickname Nicholas the Bloody or Vile Nicholas by his political adversaries due to the Khodynka Tragedy, anti-Semitic pogroms, Bloody Sunday, the violent suppression of the 1905 Russian Revolution, the executions of political opponents, and his perceived responsibility for the Russo-Japanese War (1904-1905). Soviet historians portray Nicholas as a weak and incompetent leader whose decisions led to military defeats and the deaths of millions of his subjects.

In a state of total war, the major participants threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. World War II was the deadliest conflict in human history, marked by 50 to 85 million fatalities, most of whom were civilians in the Soviet Union and China. It included massacres, the genocide of the Holocaust, strategic bombing, premeditated death from starvation and disease and the only use of nuclear weapons in war.
