the large-scale expansion of British imperial power. By 1830, the British empire had, of course, existed for centuries, and had already experienced many boons and setbacks. Perhaps the most significant blow to its power occurred in the late 18th century with the successful revolt of its 13 American colonies, an event which would eventually result in the formation of the United States as we now know it. During the 19th century, the British empire extensively expanded its colonial presence in many parts of Africa, in India, in the middle-east and in other parts of Asia. This process has had many long-term effects, including the increased use of the English language outside of Europe and increased trade between Europe and distant regions. It also, of course, produced some long-standing animosity in colonized regions.
