一八三〇年代の四国同盟

――ロシアの対イギリス政策の視点から――

抄録

The Quadruple Alliance, which was signed by Russia, Great Britain, Austria and Prussia on November 20, 1815, established the foundation of the Congress System. However, the main object of this Alliance was the prevention of another instance of French aggression. In the 1830s, the international order was threatened by the French July Monarchy, which wanted to influence neighboring countries through ideas of liberalism. The autocrat of Russia, Tsar Nicholas I, who was afraid of these ideas, tried to prevent the spread of French influence. Many previous studies have emphasized that he strengthened relationships with the Holly Alliance. However, this study focuses on Russia’s relationship with Great Britain and reveals the Russo-British partnerships in the Quadruple Alliance for the defense of the Vienna System when Britain was governed by the liberal Whig Party during most of the 1830s.

Although there was a liberal ideological identity, in both Great Britain and France in the 1830s, the two countries had many conflicts of interest in Europe and the Near East. The Whig government never permitted France to expand its influence over Belgium and Syria. For example, when a son of the King of France was recommended as the new Belgian king in January 1831, the British Foreign Secretary Palmerston rejected this idea, because Britain could not agree to the practical annexation of Belgium by France. In addition, since Britain showed negative attitudes to France in 1831, Russia could be sure of Britain’s commitment to the Continent through the Quadruple Alliance. Although in 1832 the ideological differences between Russia and Britain appeared with the passing of the Reform Act in Britain and by means of Belgian independence, Russia relied on Britain to deflect French aggression to neighboring countries. However, after the Treaty of Unkiar-Skelessi, which was signed by Russia and the Ottoman Empire on July 8, 1833, Britain approached France because they did not agree with the expansion of Russia’s influence in the Near East.

Nevertheless, during the Second Syrian Crisis, when the divergent and conflicting of Anglo-French interests in the Near East resurfaced, Russia approached Britain and took the initiative to develop the First Straits Convention, signed without France on July 15, 1840. Since “disgraced” France was threatening its neighboring countries into signing another convention, Russia demanded Britain’s commitment to defend Europe. Britain agreed to deflect the French invasion, although it did not want to sign a formal agreement. Russia used the Quadruple Alliance as a tool for involving liberal Britain in consistent defense against France in the 1830s. This Alliance contributed to the preservation of the Vienna System even after the collapse of the Congress System through the continued solidarity of the Four Powers against France.
