United States, in which the indigenous people were exterminated to the extent that they became a small minority in their lands.

We should be careful to distinguish between European settlers seeking independence from the states that founded their countries (as happened in the revolutionary war) and the struggle between indigenous people and imperial powers seeking to dominate them. While conditions for poor British settlers in the colonies that are now the United States may have included mistreatment and poverty, it would be a mistake to call this an imperial relationship, as a crucial part of imperialism is that one power is dominating another people, their land, and their resources.

Centering the power struggle between European settlers and Britain obscures the fact that both were committed to the extermination and/or subjugation of the indigenous people of North America in order to gain access to their land and extract its resources. Such instances can be understood as examples of settler colonialism, in which a core function of colonies is to provide a place for members of the ruling colonial power to settler. Settler colonies often experience conflict between settlers and the colonial power, with both sides competing to wield imperialist power over the indigenous people of the land where the colonies exist.

While the specifics of imperialism vary the history of world powers is the history of imperialism: from the Roman Empire to the Ottoman Empire, European colonial powers, Japan, the United States, and the USSR. States wielding their power to subjugate others has been nearly omnipresent over the course of recorded history.

Imperialism has been present throughout much of world history. The Roman Empire might be the most famous example. Over hundreds of years, the Roman Empire expanded, taking over large territories across Europe and parts of Africa and Asia. While the empire was stable for a long time, eventually in-fighting and the division of the empire lead to its collapse.

The Japanese also formed an empire that lasted between 1868 and 1947. During the Meiji Restoration period of the late nineteenth century, Japan underwent massive industrialization and militarization which helped make it a world power. Led on by a rise in nationalistic feeling, Japan took territories in Korea, the Philippines, and China as part of its empire. World War II played a large role in the empire's eventual dissolution.

There are many examples of imperialism. Imperialism is when a country controls another country politically and/or economically, often against the will of the people of the country. One example of imperialism is when the British established colonies in North America. The British established thirteen colonies in what is now the United States. The British established these colonies for the benefit of Great Britain. The colonies provided British industries with raw materials and resources. The British industries could then sell the finished products to the colonies. The British also made rules, laws, and policies for the operation of the colonies. By having colonies, Britain was able to have more power in the world. Eventually, the colonists didn’t want to be ruled by Great Britain and had to fight for their freedom.

Another example of imperialism is when the United States fought Spain in the Spanish-American War. The United States was looking to become a world power. We wanted to get colonies that we could control. As a result of the Spanish-American War, we got control over Puerto Rico, Guam, and the Philippines. The people of the Philippines wanted to become independent and weren’t happy when we took them over. We were able to use these colonies as places where our navy could stop and dock in order to get supplies and fuel. We also were able to trade with our colonies.

Other countries like Spain, France, and the Netherlands had colonies throughout the world. Spain controlled much of Central and South America for reasons similar to those of Britain. Spain benefited economically, politically, and militarily by having colonies in Central and South America. The French had colonies in North America and Africa. The Dutch had colonies in Africa and Asia. Countries established colonies for their benefit, even if the people didn’t want to be colonized by these countries.

Imperialism is the process initiated by a dominant country aiming to impose its ideas, agenda, and interests on another country considered less dominant.

The disagreement between the United States and the Union of Soviet Socialist Republics with regards to capitalism and communism led to the Cold War, which became a front for imperialism by the two countries involving other states in far-flung regions. Both the United States and the USSR sought support from different countries. They imposed their ideas on these countries and supported governments and rebels in order to enforce and protect their interests. 

The United States sanctions against Cuba and the conflict staged during the Bay of Pigs are considered acts of imperialism. The United States employed its vast resources in attempts to overturn a sovereign nation’s decision.

The word "imperialism" describes a process where a nation attempts to expand its influence beyond its own borders by gaining control of territories or peoples. This can come in a number of different guises, most of which were interrelated.

One obvious example of imperialism would be when a nation annexes another territory, as the United States did with the Philippines and Puerto Rico after the Spanish-American War. These territories had belonged to Spain, and the United States, as the victors, formally annexed them rather than allowing them their independence. Another classic example of this form of imperialism would be the control of India by Great Britain from the mid-eighteenth to the twentieth century.

Another form of imperialism would be economic imperialism. This can take many forms, but one of the most blatant historical examples of economic imperialism was the process of carving China up into "spheres" of economic influence among the powers of Europe in the late nineteenth century. Great Britain, Germany, France, Japan, and other nations each controlled trade in Chinese ports, and they alone could dictate the terms of trade. The attempt by the United States to open markets by what was called an "Open Door" policy, but this too, was only a means of opening Chinese markets to Western goods on terms imposed by Western powers. 

Imperialism in all forms usually involved "cultural" imperialism, where the imperial power attempts to impose, usually in the name of modernity and charity, aspects of its own culture on people around the world. This has proven especially true of religion. 

Imperialism is defined as "one country taking over the people and resources of another country"

The United States became an imperial power as a result of the Spanish American War.  The U.S. took control of the Philippines, Guam and Puerto Rico.  

European powers such as Spain, Portugal and England carved up most of Africa by the turn of the 20th century.   

One country definitely comes to mind when I think of imperialism.  Britain. According to Angus Maddison's book "The World Economy," by 1922 the British Empire had just about one fifth of the world's population under its influence and covered almost a quarter of the Earth's total land areas.  

The British Empire was not just a few colonies in the new world Americas and modern Canada.  Great Britain had large influences over Australia, which was founded as a British penal colony.  Britain also had a massive presence in India and Burma.  Many of the Caribbean islands owe their start and governance to the British Empire.  Africa was not immune from Britain's influence either.  South Africa, Egypt, Nigeria, and Kenya all were part British imperialism.   

Britain still holds claim to many places to this day.  The British Virgin Islands for example.  Sure, you can claim that the U.S. is an example of imperialism, and I don't disagree.  I do believe that Britain is the best example though.
