The Three Caesars' Alliance or League of the Three Emperors (German: "Dreikaiserabkommen" , Russian: Союз трёх императоров ) was an alliance between the German Empire, the Russian Empire and Austria-Hungary, from 1873 to 1887.
 Chancellor Otto von Bismarck took full charge of German foreign policy from 1870 to his dismissal in 1890.
 His goal was a peaceful Europe, based on the balance of power.
 Bismarck feared that a hostile combination of Austria, France and Russia would crush Germany.
 If two of them were allied, then the third would ally with Germany only if Germany conceded excessive demands.
 The solution was to ally with two of the three.
 In 1873 he formed the League of the Three Emperors, an alliance of the Kaiser of Germany, the Tsar of Russia, and the Kaiser of Austria-Hungary.
 Together they would control Eastern Europe, making sure that restive ethnic groups such as the Poles were kept in control.
 It aimed at neutralizing the rivalry between Germany’s two neighbors by an agreement over their respective spheres of influence in the Balkans and at isolating Germany’s enemy, France.
 The Balkans posed a more serious issue, and Bismarck's solution was to give Austria predominance in the western areas, and Russia in the eastern areas.
The Austro–Serbian Alliance of 1881 was a secret political alliance signed on 28 June 1881 between the Austro-Hungarian Empire and the Principality of Serbia.
 It resulted in the effective association of Serbia with Austria-Hungary and the coming Triple Alliance.
 The Balkans had been divided into spheres of influence, where Austria took the western part (including Serbia) and Russia took the eastern part (including Bulgaria).
 The treaty came after the railway convention of 6 April 1881 for the construction of the Belgrade–Niš section of the Vienna–Constantinople railway, and the trade treaty of 6 May 1881 which made Austria-Hungary virtually the sole market for agricultural products from Serbia and thereby dominant.
The Dual Alliance was a defensive alliance between Germany and Austria-Hungary, which was created by treaty on 7 October 1879 as part of Bismarck's system of alliances to prevent or limit war.
 The two powers promised each other support in case of attack by Russia.
 Also, each state promised benevolent neutrality to the other if one of them was attacked by another European power (generally taken to be France, even more so after the Franco-Russian Alliance of 1894).
 Germany’s Otto von Bismarck saw the alliance as a way to prevent the isolation of Germany and to preserve peace, as Russia would not wage war against both empires.
The Reinsurance Treaty, (June 18, 1887), a secret agreement between Germany and Russia arranged by the German chancellor Otto von Bismarck after the German-Austrian-Russian "Dreikaiserbund" or League of the Three Emperors, collapsed in 1887, because of competition between Austria-Hungary (Franz Joseph I) and Russia (Alexander III) for spheres of influence in the Balkans.
 The treaty provided that each party would remain neutral if the other became involved in a war with a third great power, though this would not apply if Germany attacked France or if Russia attacked Austria.
 Bismarck showed the Russian ambassador the text of the German-Austrian alliance of 1879 to drive home the last point.
 Germany paid for Russian friendship by agreeing to the Russian sphere of influence in Bulgaria and Eastern Rumelia (now part of southern Bulgaria) and by agreeing to support Russian action to keep the Black Sea as its own preserve.
 When the treaty was not renewed in 1890, a Franco-Russian alliance rapidly began to take shape.
Q1 of "Hamlet", or the "First Quarto" as it is also called, is a short early text of the Shakespearean play.
 The intended publication of the play is entered in the Stationers' Register in 1602 by James Roberts, but Q1 was not published until summer or autumn 1603.
 It was published by the booksellers Nicholas Ling and John Trundell, and printed by Valentine Simmes.
 Roberts later printed the "Second Quarto" (Q2).
The Reichstadt agreement was an agreement made between Austria-Hungary and Russia in July 1876, who were at that time in an alliance with each other and Germany in the League of the Three Emperors, or "Dreikaiserbund".
 Present were the Russian and Austro-Hungarian emperors together with their foreign ministers, Prince Gorchakov of Russia and Count Andrassy of Austria-Hungary.
 The closed meeting took place on July 8 in the Bohemian city of Reichstadt (now Zákupy).
 They agreed on a common approach to the solution of the Eastern question, due to the unrest in the Ottoman Empire and the interests of the two major powers in the Balkans.
 They discussed the likely Russo-Turkish War of 1877–1878, its possible outcomes and what should happen under each scenario.
The Anti-Coup Alliance (also known as the National Alliance Supporting Legitimacy) is a coalition in Egypt formed to defeat the ouster of former president Mohamed Morsi.
 The coalition is made up of approximately 40 Islamist parties and groups.
 The coalition has called upon the opposition to break ties with figures they call "corrupt" from the Mubarak regime.
 Notably, the political wing of the group (the Building and Development Party) and the Wasat Party did not take part in protests held by pro-Morsi forces during the week of 18 October 2013.
 The alliance offered a new reconciliation initiative that does not include the reinstatement of Morsi on 26 October 2013; al-Gama'a al-Islamiyya, Egyptian Islamic Jihad and the Homeland Party are not calling for the reinstatement of Morsi, while the Virtue Party, Authenticity Party and the Muslim Brotherhood are still demanding that Morsi be reinstated as president.
 The group has reached out to what it called "fellow revolutionaries" to cooperate with them against the protest law in Egypt in order to jointly organize protests; Kefaya objected to the call for cooperation.
 Members of the Building and Development Party, the political arm of al-Gama'a al-Islamiyya, wanted to meet with Yasser Al Borhamy, the deputy head of the Salafist Call as well as Emad Abdel Ghaffour, who is the head of the Homeland Party.
 Al Borhamy reportedly could not meet with the members, while Ghaffour asked them to stop demonstrations before talks could begin and rebuffed their demands for the reinstatement of Morsi and the bringing back of the Shura Council that was dissolved.
 Borhami denied being asked to serve as a mediator, though he stated that he would act as a mediator if there were no preconditions.
 The alliance has said it will boycott the 2014 constitutional referendum.
 Various groups and parties within the alliance including al-Gama'a al-Islamiyya, the Building and Development Party, the Islamic Party, the Freedom and Justice Party and the Virtue Party have criticized the Nour Party for its support of the draft constitution.
 The Islamic Party has not participated in meetings with the group because of what Mohamed Abu Samra (the secretary-general of the party) called the "brotherhood's radical thought".
 The Salafist Front issued a statement on 30 April 2014 that called on the alliance to temporarily stop its actions in order to avoid more violence; the alliance did not suspend its activities in response.
 Egyptian Prime minister Ibrahim Mahlab issued a decree on 16 October 2014 banning the alliance.
 Another decree was issued on 30 October 2014 which dissolved the alliance.
 A court postponed the appeal of the dissolution of the alliance until 13 November 2014.
The Triple Alliance, also known as the Triplice, was a secret agreement between Germany, Austria-Hungary, and Italy formed on 20 May 1882 and renewed periodically until it expired in 1915 during the Diplomatic history of World War I.
 Germany and Austria-Hungary had been closely allied since 1879.
 Italy sought support against France shortly after it lost North African ambitions to the French.
 Each member promised mutual support in the event of an attack by any other great power.
 The treaty provided that Germany and Austria-Hungary were to assist Italy if it was attacked by France without provocation.
 In turn, Italy would assist Germany if attacked by France.
 In the event of a war between Austria-Hungary and Russia, Italy promised to remain neutral.
The Central Powers (German: "Mittelmächte" ; Hungarian: "Központi hatalmak" ; Turkish: "İttifak Devletleri" or "Bağlaşma Devletleri" ; Bulgarian: Централни сили "Tsentralni sili" ), consisting of Germany, Austria-Hungary , the Ottoman Empire and Bulgaria – hence also known as the Quadruple Alliance (German: "Vierbund" ) – was one of the two main factions during World War I (1914–18).
 It faced and was defeated by the Allied Powers that had formed around the Triple Entente.
 The Powers' origin was the alliance of Germany and Austria-Hungary in 1879.
 The Ottoman Empire and Bulgaria did not join until after World War I had begun, although the Ottoman Empire retained close relations with both Germany and Austria-Hungary since the beginning of the 20th century.
The Holy Alliance (German: "Heilige Allianz" ; Russian: Священный союз , "Svyashchennyy soyuz"; also called the Grand Alliance) was a coalition created by the monarchist great powers of Russia, Austria and Prussia.
 It was created after the ultimate defeat of Napoleon at the behest of Tsar Alexander I of Russia and signed in Paris on 26 September 1815.
 The intention of the alliance was to restrain liberalism and secularism in Europe in the wake of the devastating French Revolutionary Wars, and the alliance nominally succeeded in this until the Crimean War (1853–1856).
 Otto von Bismarck managed to reunite the Holy Alliance after the unification of Germany but the alliance again faltered by the 1880s over Austrian and Russian conflicts of interest with regard to the dismemberment of the Ottoman Empire.
