Invade, from the Latin "Invasion" this term refers to an action not only human, but also of various organisms of nature. Invade means occupying a space that is not reciprocated, in general, whoever invades a place should not be there since the conditions established there indicate private property. The different organisms that can occupy a space that is not theirs do so for some need, either biological or cultural, then we will take a brief walk through the history of human society where we will find different feelings, causes and consequences of a invasion.
The invasions in history show us a human capacity to always want to dominate a territory, to prevail in life with a portion of the domain, either land or over any group of people, it was really important to the point of committing everything type atrocities, damages and crimes. If we go to a specific event as an example, The Second World War was an event in which one of the largest and most important invasions in the world was enshrined, the separation of a country, entailed the imposition of norms and laws that did not correspond to the human rights of any person, therefore, it was an invasion. The Jews eradicated in the country by being considered a scum were invading a space that for the Nazis was their own.
Civilizations and society are in integrity the best example of invasion, but there are organisms that act as invaders in certain spaces that, as the generic concept dictates, should not be there. Diseases caused by pathogens are caused by invasions of these into the body. They are generally called bacteria, strains or viruses that survive in a given environment.
The results of an invasion may vary depending on the objectives of the invaders and defenders, the success of the invasion and the defense, and the presence or absence of an agreement between the contestants. The most typical result is the loss of territory, almost always accompanied by a change in government and often by the loss of direct control of the government by the loser. This sometimes implies that the country becomes a satellite state, often with the requirement to pay compensation or tribute to the winner. In rare cases, the result of a successful invasion is simply a return to the status quo; This can be seen in wars of attrition, where the main strategic objective is the destruction of supplies and people.
