Imperialism derived from the Latin originated word Imperium, meaning Supreme power or Sovereignty or simply rule. It came into normal usage in late 1870 in Britain as a negative connotation. This term is associated with western political and economic dominance in Asian and African regions. Imperialism is defined as the act of a country, empire or state extending or dominating a state by the use of power through extending its territories. It also includes the factor of exploiting, looting and plundering the colonized states and its resources and people. Imperialism leads to colonialism.
Imperialism operates when a powerful or a strong nations try to dominate the cultural life, politics, economy and or trade of a weak nation or region. After the era or the emerging industrial revolution in late 18’s or 19th century, imperialism became an essential practice for looting and capturing the resources of the weak nation by the powerful ones. It became a common practice of European nations looting the best sources of raw material for their manufacturing products.
“Industrialized countries of the west sought to expand their economies by obtaining raw materials which could be transported back to factories, turned into manufacturing goods, and shipping back to the colonies markets for sale”
Imperialism is considered as an act of moral reprehension because it is in modern times used as an act of controlling and degrading financial and foreign policies the oppressors. Never in the history of mankind did any anyone see or heard or read about a mission of civilizing a nation as Europeans did. The traces of imperialism links back in times when Spain and Portugal partitioned the world by signing the treaty of Tordesillas in 7th June 1494, to which they later clearly declared as an act of hegemony. Chinese imperialism is also famous for its expansion. Similarly, we can trace its operations in the late 1870s and Asia and Africa, when British came in the Subcontinent and Africa. In the name of so-called White Man’s burden to civilize the whole world or bunch of all those countries and states which for them were not either civilized or were undeveloped. In Sub Continent they came by the excuse to trade as an East India Company and then slowly invaded and plundered the whole continent.
Imperialism has played very much of its important role in the major regions of the world including Asia, specifically China, Japan, Assyria, Egypt, Rome, France, Ottoman Empire. Also in the era of Mongols, imperialism is considered to be the fundamental component of their conquests and powerful invasions. Genghis Khan and some other famous warlords used it as tactics to predate other weak states. Some historically recognized the wave of imperialism also hit Muslim state and region. Jerusalem, currently known as Palestine and Kashmir are also counted in those states which are extremely affected by the invasion of the more powerful; neighboring states. 
Che Guevara famous speech on behalf of Cuban Government to the Ministerial meeting is also the proof of the consequences face by the Cuban people from imperialism,
“Cuba is on the alert, distinguished delegates because she knows that imperialism would perish enveloped in flames…The situation of the worlds intense”.
Not only Asia and Africa but also some part of the Europe also had a part of Imperialism and colonization. North America which is now known as Canada had also faced the impacts and consequences of Imperialism in its times. There were many poems and stories written by those Red Indians who were the natives and are considered to be the natives of the region, depicting the harsh and brutal treatment of the colonizers with the colorized ones.
Although imperialism is normally used by the more powerful political lords or states to forcefully invade the regions which are either politically or financially unstable or are considered to be as the nations which are not relying on or flourishing under a unified law or system. This is the basic or most commonly used tactics by the powerful nation on the weak ones. Not only financial or political but also cultural and economic invasion and suppression is also the part of the Imperialism. It is for most of the times being done through either by sea route or trade routes. The very European World System Theory used by the invaders as tools to Imperialism. The terms core and periphery are applied to the nation that is imperialized or invaded. The core is the area or nation which is considered to be as rich and high area of Income and Profit. Contrary to this the Periphery is the nation or state that is being invaded or highly likely to be invaded, that is the area of low profit and income.
Three important eras of imperialism have changed the history of the world. In the period of between 15th to 18th centuries, major powerful nations including England, France, and Spain had built their power franchises in the regions of Africa, India and East Indies. This very building of invasion has led the suppressed nation to rise against the imperialism. This expedition and invasion have caused or molds the world into new order.
SPREAD AND IMPACTS
Imperialism lasts its effects on minds and histories for many years and some time for centuries. The very impact of some major imperialist invasions in the history of Mankind has affected in great. Its impact has changed the scenario of the world within no time. Imperialism has affected many cultures and civilizations badly and has almost altered their lifestyle and social construct. The use of force and violence in imperialism affects the psychological pattern of the inhabitants of the affected area majorly. The very brought and the lifestyle of the natives of the particular area completely changes into a new spectrum. Like, British invasion in the subcontinent was largely focused on the collection of resources and empowerment.
Many students of history are interested in studying Joseph Conrad’s Heart of darkness because of its importance in fiction. It displays many important themes like Psychological and Metaphysical the most interesting theme is imperialism which is widely read and appreciated. The novel shows the Brutal and harsh dealing of Whiteman with Blacks. Under the garb of Whiteman’s burden to civilize the world which is not so unified under the one law or state. 
“The title I am thinking of is The Heart of Darkness, but the narrative is not gloomy. The criminality of inefficient and pure selfishness when tackling the civilizing work in Africa is a justifiable idea.” 
Conrad goes on criticizing the attempt to imperialize Africa by British is that it only takes a brutal force to end the peace and to begin the wave of violence and killing. When you have force and capital, all is yours. Since the very claim of power is nothing but the weaknesses of others to accept your command and suppression. Imperialism not only stays in Politics and Economic. It also reaches to the zenith of Cast, Creed, and Color. White only takes possession of Black’s life, wealth, and resources by feeling superior in Color cast or creed. This very conquest of taking possession of things or plundering or taking from those just because they have a little flatter nose or their complexion is not so attractive than invaders.
We are living now in a concept of Globalization. The idea that declares the acceptance, prosperity, and peace for all itself contradict in many ways. It tells us about the acceptance of all the global cultures and nation and their beliefs under on umbrella of peace and prosperity. But in fact, what globalization is the only an instrument used to beat or boast of the victory of powerful nations or states. It is used to highlight the importance and vastness of the cultures and values of the powerful nations and to hide the miseries and importance of the working class or underdeveloped countries. Under the rule of international organizations and Media, it is attempting to hide their hideous or illegal crimes and to present them as legitimate ones.
The 19th-century Globalization is the modern form of Globalization because it involves industrial scale growth. The evolution of Industrial trade made the Imperialist to attain the policy of globalization cum Imperialism for the cheap production with the rapid growth of the economy. Imperialism also effects in another way around in the form of Modern banking and modern financial crisis. The modern agents of Globalization Imperialism include some renowned international organizations including IMF, World Bank, etc. they aimed at creating loans for the underdeveloped or poor states so to meet up their financial needs or to balance their deficit. But it all comes up with some imposed rules and regulations to that capture or hijack the running economy of the states and make them bankrupt. 
“The Critics believe that the conditions? Strategies are imperialistic strategies to capture the developing economies. An economist, Joseph Stiglitz, (a Nobel prize winner ND former Chief Economist at the World Bank) argued against the IMF for the policies that he says often make the fund’s clients worse not better off.”(Globalization_capitalist_imperialism).
Imperialism spreads its wings to cultural spectrum also. It also predates the cultural upbringing and conscious of the people of powerfully weak tradition. Imperialist considering them as the salt of the earth makes them to spread their cultural values forcefully and to dominate others on cultural regimes. The most dominant cultures or powers of the world are not ready to accept the growing cultures of other nations or inferior ones. The modern use of technology and media has made an easy excess effect other growing cultures.
“The principal target of cultural imperialism is the political and economic exploitation of youth. Imperial entertainment and advertisement target young people who are most vulnerable to U.S. commercial propaganda. The message is simple and direct: ‘modernity’ is associated with consuming U.S. media products.” 
Imperialism is not a new concept in the modern world. It was the when some mother nations or states started to take control of the smaller country or state ort colony for political, cultural and economic domination. Imperialism has, with all other factors, changed or reshaped the world order. It has greatly affected and reshaped the global system. As there are a variety of opinions and views about Imperialism depending upon the reference point or perspectives of thinking from different constructs. Imperialism has always effected in the form of colonization. This is a negative view. I can be seen from the arguments that the powerful still suppress the weak. There is no point in civilizing the smaller colonies or states. In the name of Civilizing, all there is hard work, cheap labor, violence, and suffering. These events lead to post-traumatic effects in their psychology. The colonies and the natives were not allowed to live their lives according to their beliefs and traditions. They have usually deprived off their freedom. There were exploitation and hunger everywhere.
Natives were forced to live in these conditions. They were forced to accept the culture, tradition and sometimes religion of dominating powers, failure to do so resulted in killing innocent lives. The lives of the children, women and old people also became gloomy. The children were put to work salve as the best source for the cheap labor. Millions of people had died from this. They have deprived off all their lands, their houses were burnt, and their resources were plundered from them. They were looted from all their valuables, even life.
Imperialism is never a matter of good cause and effect. Natives are heavily exploited and forced to live. All African and Asian were deprived of their basic rights. They were forced to accept the new culture. Imperialist powers took all their assets and gave nothing in return. Imperialist wanted resources, raw material, national glory and their so-called white man’s burden to civilize them. In their view, what they were doing is helping those poor colonies. But in reality, all they were doing is hurting and exploiting them. They were creating chaos among the smaller communities, causing anarchy and civil war among them. This was never productive.
Imperialist is just like a landowner who has a slave or a worker for him working five out of seven days in a week. Their looting and plundering changed the world into a place which is now pretty much harder to live in. It wasn’t just looting. If they had to steal it from mother nature that was not a problem. But they let and forced natives to dig and produce for them. They have imperialized the world 100 years back, but still, we are facing and experiencing the effects of it greatly.
