who had the support of France, the Netherlands and (indirectly) Spain. A favoured British diplomatic strategy involved subsidising the armies of continental allies (such as Prussia), thereby turning London's enormous financial power to military advantage. Britain relied heavily on its Royal Navy for security, seeking to keep it the most powerful fleet afloat, eventually with a full complement of bases across the globe. British dominance of the seas was vital to the formation and maintaining of the British Empire, which was achieved through the support of a navy larger than the next two largest navies combined, prior to 1920. The British generally stood alone until the early 20th century, when it became friendly with the U.S. and made alliances with Japan, France and Russia. Germany was now the main antagonist. 1814–1914 The 100 years were generally peaceful--a sort of Pax Britannica enforced by the Royal Navy. There were two important wars, both limited in scope. The Crimean War (1853–1856) saw the defeat of Russia and its threat to the Ottoman Empire. The Second Boer War (1899–1902) saw the defeat of the two Boer republics in South Africa. London became the world's financial centre, and commercial enterprise expanded across the globe. The "Second British Empire" was built with a base in Asia (especially India) and Africa. First World War 1920s After 1918 Britain was a "troubled giant" that was less of a dominant diplomatic force in the 1920s than before. It often had to give way to the United States, which frequently exercised its financial superiority. The main themes of British foreign policy included a leading role at the Paris Peace Conference of 1919–1920, where Lloyd George worked hard to moderate French demands for revenge on Germany. He was partly successful, but Britain soon had to moderate French policy toward Germany further, as in the Locarno Treaties of 1925. Furthermore, Britain obtained "mandates" that allowed it and its dominions to govern most of the former German and Ottoman colonies. Britain became an active member of the new League of Nations, but its list of major achievements was slight. Disarmament was high on the agenda, and Britain played a major role following the United States in the Washington Naval Conference of 1921 in working toward naval disarmament of the major powers. By 1933 disarmament agreements had collapsed and the issue became rearming for a war against Germany. Britain was partially successful in
