The late 19th century saw the creation of several alliances in Europe. Germany, Italy, and Austria-Hungary formed a secret defensive alliance called the Triple Alliance. France and Russia also developed strong relations with one another, due to the financing of Russia's Industrial Revolution by French capitalists. Although it did not have a formal alliance, Russia supported the Slavic Orthodox nations of the Balkans and the Caucasus, which had been created in the 19th century after several wars and revolutions against the Ottoman Empire, which by now was in decline and ruled only parts of the southern Balkan Peninsula. This Russian policy, called Pan-Slavism, led to conflicts with the Ottoman and Austro-Hungarian Empires, which had many Slavic subjects. Franco-German relations were also tense in this period due to France's defeat and loss of land at the hands of Prussia in the Franco-Prussian War. Also in this period, Britain ended its policy of isolation from the European continent and formed an alliance with France, called the Entente Cordiale. Rather than achieve greater security for the nations of Europe, however, these alliances increased the chances of a general European war breaking out. Other factors that would eventually lead to World War I were the competition for overseas colonies, the military buildups of the period, most notably Germany's, and the feeling of intense nationalism throughout the continent.
