The Austrian, Prussian, and Russian monarchist superpowers joined together to form the Holy Alliance.
It was established at the request of Russian Emperor (Tsar) Alexander I and signed in Paris on September 26, 1815, following Napoleon's final defeat.
Following the catastrophic French Revolutionary War and the Napoleonic War, the alliance sought to contain liberalism and secularism throughout Europe, and up until the Crimean War, it looked to have been successful in this endeavour.
Following the unification of Germany in 1871, Otto von Bismarck was able to bring the Holy Alliance back together, but by the 1880s, conflicts of interest between Russia and Austria over the collapse of the Ottoman Empire caused the alliance to break down once more.
