The history of the foreign relations of the United Kingdom covers English, British, and United Kingdom's foreign policy from about 1500 to 2000. For the current situation since 2000 see foreign relations of the United Kingdom.
Britain from 1750 to the 1910s took pride in an unmatched economic base; comprising industry, finance, shipping and trade that largely dominated the globe. Foreign policy based on free trade (from the 1840 to 1920s) kept the economy flourishing. The overseas First British Empire was devastated by the loss of the thirteen American colonies in a war when Britain had no major allies. The Second British Empire was built fresh in Asia and Africa and reached its zenith in the 1920s. Foreign policy made sure it was never seriously threatened. The Statute of Westminster granted effective independence to Britain's self governing Dominions in 1931. In the era of Pax Britannica, 1815 to 1914, The British dominated world trade, finance and shipping. In what historians call "The Imperialism of Free Trade", London had a strong political voice in many nations in Latin America and Asia. The Royal Navy was used to help suppress the African slave trade, and to reduce piracy.
A favoured diplomatic strategy against France before 1815 was subsidising the armies of continental allies, such as the Kingdom of Prussia, thereby turning London's enormous financial power to military advantage. After 1815 the British Empire was kept secure by reliance on the Royal Navy. It remained the most powerful fleet afloat with a vast network of bases across the globe. London ensured it was larger than the next two largest navies combined.
