World War IWorld War I or the First World War, often abbreviated as WWI or WW1, known contemporaneously as the Great War, was a major global conflict lasting from 1914 to 1918. It was fought between two coalitions, the Allies and the Central Powers. Fighting took place throughout Europe, the Middle East, Africa, the Pacific, and parts of Asia. The first decade of the 20th century saw increasing diplomatic tension between the European great powers.
Kingdom of ItalyThe Kingdom of Italy (Regno d'Italia, ˈreɲɲo diˈtaːlja) was a state that existed from 17 March 1861, when Victor Emmanuel II of Sardinia was proclaimed King of Italy, until 2 June 1946, when civil discontent led to an institutional referendum to abandon the monarchy and form the modern Italian Republic. The kingdom was established through the unification of several states over a decades-long process, called the Risorgimento. That process was influenced by the Savoy-led Kingdom of Sardinia, which can be considered Italy's legal predecessor state.
Russian EmpireThe Russian Empire, also known as Imperial Russia, was the final period of the Russian monarchy from its proclamation in November 1721, until its dissolution in late 1917. It consisted of most of northern Eurasia. The Empire succeeded the Tsardom of Russia following the Treaty of Nystad. The rise of the Russian Empire coincided with the decline of neighbouring rival powers: the Swedish Empire, the Polish–Lithuanian Commonwealth, Qajar Iran, the Ottoman Empire, and Qing China.
Battle of TsushimaThe Battle of Tsushima (Цусимское сражение, Tsusimskoye srazheniye), also known in Japan as the Battle of the Sea of Japan, was the final naval battle of the Russo-Japanese War, fought on 27–28 May 1905 in the Tsushima Strait. A devastating defeat for the Imperial Russian Navy, the battle was the only decisive engagement ever fought between modern steel battleship fleets and the first in which wireless telegraphy (radio) played a critically important role.
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.
Allies of World War IThe Allies, or the Entente Powers, were an international military coalition of countries led by France, the United Kingdom, Russia, the United States, Italy, and Japan against the Central Powers of Germany, Austria-Hungary, the Ottoman Empire, and Bulgaria in World War I (1914–1918). By the end of the first decade of the 20th century, the major European powers were divided between the Triple Entente and the Triple Alliance. The Triple Entente was made up of the United Kingdom, France, and Russia.
Franz Joseph I of AustriaFranz Joseph I or Francis Joseph I (Franz Joseph Karl fʁants ˈjoːzɛf ˈkaʁl; Ferenc József Károly ˈfɛrɛnt͡s ˈjoːʒɛf ˈkaːroj; 18 August 1830 – 21 November 1916) was Emperor of Austria, King of Hungary, and the ruler of the other states of the Habsburg monarchy from 2 December 1848 until his death on 21 November 1916. In the early part of his reign, his realms and territories were referred to as the Austrian Empire, but were reconstituted as the dual monarchy of the Austro-Hungarian Empire in 1867.
Russian Revolution of 1905The Russian Revolution of 1905, also known as the First Russian Revolution, began on 22 January 1905. A wave of mass political and social unrest then began to spread across the vast areas of the Russian Empire. The unrest was directed primarily against the Tsar, the nobility, and the ruling class. It included worker strikes, peasant unrest, and military mutinies. In response to the public pressure, Tsar Nicholas II was forced to go back on his earlier authoritarian stance and enact some reform (issued in the October Manifesto).
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.
February RevolutionThe February Revolution (Февра́льская револю́ция), known in Soviet historiography as the February Bourgeois Democratic Revolution and sometimes as the March Revolution, was the first of two revolutions which took place in Russia in 1917. The main events of the revolution took place in and near Petrograd (present-day Saint Petersburg), the then-capital of Russia, where long-standing discontent with the monarchy erupted into mass protests against food rationing on 23 February Old Style (8 March New Style).
