The reason why Britain rose to become an "imperial empire" in the19th century is that Britain not only maintained the stability of the balance of power in the European continent through the seven-year war, but also destroyed the maritime power of France and Spain again and seized almost all the colonies of France in the North American continent and India.

Churchill said that after the Seven Years' War, "Britain became the master of the sea and land outside Europe", and he quoted horace Walpole, a British politician, as saying, "It took the Romans 300 years to conquer the world, and we conquered the world after only three wars, but now the world is twice as big as the Roman era".

Since the middle of19th century, the word "empire that never sets" has been widely used in English-speaking countries, and its application targets clearly include Britain and the United States. Its significance is not only manifested in the possession of territory, but also extends to the fields of language (English), culture (Christian culture) and art (Western art).

For example, Alexander Campbell gave a speech at 1852. Later, the word was applied to American sphere of influence. An earlier example is "boasting" in an article by 1897: "Uncle Sam's sun never sets."

In recent years, this word has been avoided and introduced into American political language. The book A Guide to American History describes how the original thirteen colonies became independent from the "wave of the British Empire", and then goes on to say that "the United States of America itself has become an empire, and its influence has finally surpassed the greatest British hegemony.

After more than two centuries of independence, the sun will never set on the territory owned by the American government, citizens and overseas troops, nor will it set over the countries within the sphere of American influence under the control of American hegemony. "
