Final answer:
Britain had limited control over different parts of the world from an economic standpoint around 1500. However, by the 19th century, the British Empire exerted extensive control over territories and became a dominant force.
Step-by-step explanation:
In 1500, Britain had limited control over different parts of the world from an economic standpoint. However, by the 19th century, the British Empire had become a dominant force, exerting extensive control over territories such as Canada, South Africa, parts of Africa, islands, Egypt, India, and ports in China. The empire's control spanned around a fifth of the world, including a quarter of its population.
With the defeat of Napoleon in 1815, the Royal Navy was able to establish British supremacy in trade and control the oceans. The British ideals of free markets helped fuel the industrial revolution and economic growth, further expanding their control and influence.
While the British Empire had extensive control during this time, it faced challenges towards the end of the century, including the crumbling Ottoman Empire, the Crimean War, and the industrialization of Germany and the United States, leading to the decline of British dominance.
