Final answer:
The British Empire's vast economic influence in the 19th century not only propelled industrialization and technological advancement but also established Britain as a global authority. This era of dominance, however, began to wane as other nations industrialized and the international competition for resources intensified, leading to the decline of British economic supremacy.
Step-by-step explanation:
The British Empire's economic influence profoundly impacted both Europe and other parts of the world during its peak in the 19th century. By the end of that century, the British Empire controlled a significant portion of global territory and population, exerting its control over a fifth of the world and twenty-five percent of its population. This not only set the stage for widespread industrialization but also promoted free market ideals and advanced technological development, such as the establishment of global shipping lines and telegraph cables, facilitating quick communication and trade.
Moreover, the might of the British Royal Navy ensured a period known as Pax Britannica, which allowed the British to arbitrate international affairs and to a great extent stop the slave trade. Nonetheless, as other nations like Germany and the United States began to industrialize, they started challenging British economic supremacy, marking the beginning of the empire's decline. Countries sought natural resources, established colonies, and the global economy became increasingly interconnected as a result of competitive imperialism, reducing the dominance of Britain.
