query: Who was the Czar before the Russian Revolution?
passage: Nicholas II of Russia
Nicholas II or Nikolai II (Russian:Николай II Алекса́ндрович, tr.Nikolai II Aleksandrovich; 18 May [O.S. 6 May] 1868 – 17 July 1918), known as Saint Nicholas the Passion-Bearer in the Russian Orthodox Church, was the last Emperor of Russia, ruling from 1 November 1894 until his forced abdication on 15 March 1917.[1] 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 execution of political opponents, and his perceived responsibility for the Russo-Japanese War (1904–1905).[2][3] Soviet historians portrayed Nicholas as a weak and incompetent leader whose decisions led to military defeats and the deaths of millions of his subjects.[4]
passage: Finnish gunboat Klas Horn
Klas Horn (ex-"Posadnik") was the flagship and an escort ship for the Russian Czar's yacht. "Posadnik" was built in Prussia in 1892 for the Montenegrin king Nicholas I. The ship was purchased by the Russian Czar after Nicholas' money ran out. After the Russian revolution, the ship was taken over by the Finnish Navy and renamed "Klas Horn", after a 16th-century admiral. She initially served as a minelayer, but was rebuilt into a gunboat in the 1920s. "Klas Horn" ended her Finnish navy service in the 1930s and served as a mothership for sea surveying.
