often blurs the differences. If a state can preserve the fiction that migrations are the result of innumerable "personal" decisions, the state may be able to claim that it is not to blame for the displacement.
Often the affected population is
transferred by force to a distant region, perhaps not suited to their way of life, causing them substantial harm. In addition, the process implies the loss of immovable property and substantial amounts of movable property when rushed. This transfer may be motivated by the more powerful party's desire to make other uses of the land in question or, less often, by disastrous environmental or economic conditions that require relocation.

Ancient Assyria in the 13th century BCE. The single largest population transfer in history was the

Specific types of population transfer
Population exchange
Population exchange is the transfer of two populations in opposite directions at about the same time. In theory at least, the exchange is non-forcible, but the reality of the effects of these exchanges has always been unequal, and at least one half of the so-called "exchange" has usually been forced by the stronger or richer participant. Such exchanges have taken place several times in the 20th century:
* The
partition of India and Pakistan

Ethnic dilution
Ethnic dilution is the practice of enacting immigration policies to relocate parts of an ethnically and/or culturally dominant population into a region populated by an ethnic minority or otherwise culturally different or non-mainstream group to dilute and eventually to transform the native ethnic population into the mainstream culture over time.

" (written during the
World War II evacuation and expulsions in Europe), observed:
:"In our time, political speech and writing are largely the defence of the indefensible. Things... can indeed be defended, but only by arguments which are too brutal for most people to face, and which do not square with the professed aims of political parties. Thus political language has to consist largely of euphemism, question-begging and sheer cloudy vagueness.... Millions of peasants are robbed of their farms and sent trudging along the roads with no more than they can carry: this is called ''transfer of population'' or ''rectification of frontiers''."

of German Nazi leaders declared forced deportation of civilian populations to be both a war crime and a crime against humanity. That opinion was progressively adopted and extended through the remainder of the century. Underlying the change was the trend to assign rights to individuals, thereby limiting the rights of states to make agreements that adversely affect them.
There is now little debate about the general legal status of involuntary population transfers: "Where population transfers used to be accepted as a means to settle ethnic conflict, today, forced population transfers are considered violations of international law." No legal distinction is made between one-way and two-way transfers since the rights of each individual are regarded as independent of the experience of others.

An interim report of the United Nations Sub-Commission on Prevention of Discrimination and Protection of Minorities (1993) says:
The same report warned of the difficulty of ensuring true voluntariness:
"some historical transfers did not call for forced or compulsory transfers, but included options for the affected populations. Nonetheless, the conditions attending the relevant treaties created strong moral, psychological and economic pressures to move."
The final report of the Sub-Commission (1997) invoked numerous legal conventions and treaties to support the position that population transfers contravene international law unless they have the consent of both the moved population and the host population. Moreover, that consent must be given free of direct or indirect negative pressure.
