YaltaYalta (: Я́лта) is a resort city on the south coast of the Crimean Peninsula surrounded by the Black Sea. It serves as the administrative center of Yalta Municipality, one of the regions within Crimea. Yalta, along with the rest of Crimea, is internationally recognised as part of Ukraine, and is considered part of the Autonomous Republic of Crimea. However, it is under the control of Russia, which annexed Crimea in 2014 and regards the town as part of the Republic of Crimea.
Narodnaya VolyaNarodnaya Volya (Наро́дная во́ля) was a late 19th-century revolutionary socialist political organization and left-wing terrorist group operating in the Russian Empire, which conducted assassinations of government officials in an attempt to overthrow the autocratic Tsarist system. The organization declared itself to be a populist movement that succeeded the Narodniks. Composed primarily of young revolutionary socialist intellectuals believing in the efficacy of terrorism, Narodnaya Volya emerged in Autumn 1879 from the split of an earlier revolutionary organization called Zemlya i Volya ("Land and Liberty").
Reinsurance TreatyThe Reinsurance Treaty was a diplomatic agreement between the German Empire and the Russian Empire that was in effect from 1887 to 1890. Only a handful of top officials in Berlin and St. Petersburg knew of its existence since it was so secret. The treaty played a critical role in German Chancellor Otto von Bismarck's extremely complex and ingenious network of alliances and agreements, which aimed to keep the peace in Europe and to maintain Germany's economic, diplomatic and political dominance.
DumaA duma (дума) is a Russian assembly with advisory or legislative functions. The term boyar duma is used to refer to advisory councils in Russia from the 10th to 17th centuries. Starting in the 18th century, city dumas were formed across Russia. The first formally constituted state duma was the Imperial State Duma introduced to the Russian Empire by Emperor Nicholas II in 1905. The Emperor retained an absolute veto and could dismiss the State Duma at any time for a suitable reason.
