The bare use of power is imperialism. Since your strength is only an accident that resulted from other people's weaknesses, Joseph Conrad wrote in his 1902 novel "Heart of Darkness," For the sake of obtaining what was available, they seized every opportunity. In 1823, the Monroe Doctrine declared that the United States would protect the Americas from European imperialism. It created the groundwork for continuing American meddling in the Western Hemisphere. Spanish colonial rule in the Western Hemisphere was put to an end in 1898 by the Spanish-American War. Spanish claims to Cuba were dropped, and the United States assumed control of Guam, Puerto Rico, and the Philippines.

Age of imperialism
A few years later, it defeated Filipino nationalists. Even though Puerto Ricans are citizens of the United States, neither independence nor full statehood have been granted to the island. Between 1870 and 1900, a fifth of the world's landmass—roughly 9 million square miles—was seized by European nations. At that time, imperialism affected about 150 million people. World War I was a result of European imperialism. Imperialism had been a major source of wealth for Germany, Austria-Hungary, France, Russia, and Great Britain. Southeast European nations bordering Russia were a part of the Austro-Hungarian Empire. The empires of Germany and Italy both included nations in Africa, as well as the former French provinces of Lorraine and Alsace. The majority of eastern Europe, including Serbia, was part of the Russian Empire, which the Allies represented.

The French Empire controlled Vietnam and the majority of northern Africa, while the British Empire controlled nations in Africa, Asia, and the Americas. When Germany and Austria-Hungary occupied small countries like Bosnia and Morocco, the Allies felt threatened. Before World War I, nationalism was also rising among conquered countries. Poles, Czechs, and Slovaks were particularly fed up with living as outcasts in the German and Austro-Hungarian empires. Bosnia and Herzegovina were under Austro-Hungarian rule when Serbian nationalists wanted it to end. When a Serbian nationalist killed Archduke Franz Ferdinand, Austria-Hungary declared war on Serbia. As a result, Russia and eventually the other Allies joined in. To defend their empires, they turned to militarism, but the results were disastrous.

Imperialism sees economics as a "zero-sum" game where there are only so many resources available. According to this theory, someone must become poorer for someone else to become richer. Imperialism uses the concept of "survival of the fittest," or social Darwinism, to justify its use of force in its expansion. The early 20th-century economist J.A. Hobson wrote in his book "Imperialism: A Study" that history has demonstrated that imperialism frequently takes advantage of the resources of the conquered nation. This could serve as the economic justification for conquering other countries and establishing an empire. Because nature is seen as nothing more than a resource to be exploited for the smallest profit, imperialism has also contributed to climate change. In a zero-sum economy, someone must lose out due to resource depletion or pollution for businesses in the developed world to succeed.

Control by one power over a dependent region or population is known as colonialism, and it frequently entails settling newcomers in another nation. Its root is the farmer-related Latin word colonus. The settlers maintain their allegiance to their home country even though they intend to live there permanently. The ancient Greek, Roman, and Ottoman empires saw the beginnings of colonialism. In the sixteenth century, improved ships allowed it to grow internationally. These ships made it possible to transport substantial numbers of colonists from one nation to another while also enslaving the colonized people. Important: Although "imperialism" and "colonialism" are frequently used interchangeably, they are not the same thing. Through various forms of control, imperialism enables one nation to rule over another. If the occupying nation does not send in settlers, it may take place without colonialism. In the late 19th century, Europeans grew their empires in Africa without planning to colonize it fully. That doesn't lessen the terrible impact imperialism had on Africa, though. Additionally, there was no colonization associated with American expansion into the Philippines and Puerto Rico.
