Nicholas II, or Nikolai II Alexandrovich Romanov (18 May [O.S. 6 May] 1868 – 17 July 1918), was the last Emperor of Russia, reigning from 1 November 1894 to 15 March 1917. Revered as Saint Nicholas the Passion-Bearer in the Russian Orthodox Church, he also held the titles of King of Congress Poland and Grand Duke of Finland. His reign marked the end of the Romanov dynasty's 304-year rule over Russia. Though Nicholas supported economic and political reforms proposed by his prime ministers, Sergei Witte and Pyotr Stolypin, his adherence to authoritarianism and reluctance to empower the Duma stymied significant progress. His reign was further undermined by aristocratic resistance and military defeats during the Russo-Japanese War and World War I, which eroded public confidence in his leadership.

Internationally, Nicholas sought to bolster Russia's position through alliances and diplomatic agreements. He signed the Anglo-Russian Convention of 1907, aiming to counter German influence in the Middle East and end the longstanding Great Game rivalry with Britain. Earlier, he had initiated the Hague Convention of 1899, a pioneering but ultimately unsuccessful effort to promote disarmament and peaceful conflict resolution. These measures were part of his broader vision to solidify the Franco-Russian Alliance and strengthen Russia's global standing.

Domestically, however, Nicholas' reign was plagued by crises and controversies. He faced widespread criticism for his government's repressive policies, particularly during moments of significant unrest. The Khodynka Tragedy, a catastrophic stampede at his coronation celebrations, set a grim tone for his rule. His apparent complicity in anti-Jewish pogroms, the violent crackdown on Bloody Sunday in 1905, and the brutal suppression of the Russian Revolution that same year further tarnished his reputation.
