Foreign relations of the United Kingdom

The United Kingdom was the world's foremost power during the 19th and early 20th centuries, most notably during the so-called "Pax Britannica"—a period of unrivaled supremacy and unprecedented international peace during the mid-to-late 1800s.

The country continued to be widely considered a superpower until the Suez crisis of 1956 and the dismantling of the British Empire left the UK's dominant role in global affairs to be gradually diminished.

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.

[1] 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.

Hitler however cut a deal with Joseph Stalin to divide Eastern Europe (23 August 1939); when Germany did invade Poland in September 1939, Britain and France declared war, and the British Commonwealth followed London's lead.

In August 1941, Churchill and Roosevelt met and agreed on the Atlantic Charter, which proclaimed "the rights of all peoples to choose the form of government under which they live" should be respected.

The cumulative costs of fighting two world wars, however, placed a heavy burden upon the home economy, and after 1945 the British Empire rapidly began to disintegrate, with all the major colonies gaining independence.
