Nicholas II (Nikolai Alexandrovich Romanov; 18 May [O.S. 6 May] 1868 – 17 July 1918) was Emperor of Russia, King of Congress Poland, and Grand Duke of Finland from 1 November 1894 until his abdication in 1917. His reign of over 22 years marked the final chapter of the Romanov dynasty, which had ruled Russia for more than three centuries. Nicholas married Alix of Hesse (later Alexandra Feodorovna), and they had five children: four daughters, Olga, Tatiana, Maria, and Anastasia, and a son, Alexei, the Tsesarevich.
Born in Tsarskoye Selo, Nicholas was the eldest son of Emperor Alexander III and Empress Maria Feodorovna. He was educated privately and trained for military service, but was widely considered ill-prepared for the demands of ruling a vast empire. As a constitutional monarch, he resisted political reform and retained autocratic control, despite the establishment of the Duma. His reign saw significant industrial growth and diplomatic engagement, including the Hague Conventions and the Anglo-Russian Convention of 1907, but was also marked by domestic unrest, military defeats, and widespread criticism.
