三帝同盟
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.
