Alexander's most significant reform as emperor was the emancipation of Russia's serfs in 1861, for which he is known as Alexander the Liberator (Алекса́ндр Освободи́тель).
Nicholas II of RussiaNicholas II (Nikolai II Alexandrovich Romanov; 1868 - 17 July 1918), known in the Russian Orthodox Church as Saint Nicholas the Passion-Bearer, was the last Emperor of Russia, King of Poland and Grand Duke of Finland, ruling from 1 November 1894 until his abdication on 15 March 1917. During his reign, Nicholas gave support to the economic and political reforms promoted by his prime ministers, Sergei Witte and Pyotr Stolypin. He advocated modernization based on foreign loans and close ties with France, but resisted giving the new parliament (the Duma) major roles.
Estonian War of IndependenceThe Estonian War of Independence, also known as the Estonian Liberation War, was a defensive campaign of the Estonian Army and its allies, most notably the United Kingdom, against the Bolshevik westward offensive of 1918–1919 and the 1919 aggression of the Baltische Landeswehr. The campaign was the struggle of the newly established democratic nation of Estonia for independence in the aftermath of World War I. It resulted in a victory for Estonia and was concluded in the 1920 Treaty of Tartu.
Northern CrusadesThe Northern Crusades or Baltic Crusades were Christian colonization and Christianization campaigns undertaken by Catholic Christian military orders and kingdoms, primarily against the pagan Baltic, Finnic and West Slavic peoples around the southern and eastern shores of the Baltic Sea, and also against Orthodox Christian Slavs (East Slavs). The most notable campaigns were the Livonian and Prussian crusades. Some of these wars were called crusades during the Middle Ages, but others, including most of the Swedish ones, were first dubbed crusades by 19th-century romantic nationalist historians.
Gulf of FinlandThe Gulf of Finland (Soome laht; Suomenlahti; Фи́нский зали́в; Finska viken) is the easternmost arm of the Baltic Sea. It extends between Finland to the north and Estonia to the south, to Saint Petersburg in Russia to the east, where the river Neva drains into it. Other major cities around the gulf include Helsinki and Tallinn. The eastern parts of the Gulf of Finland belong to Russia, and some of Russia's most important oil harbors are located farthest in, near Saint Petersburg (including Primorsk).
