Colonization or colonisation is defined as "the act or process of sending people to live in and govern another country". The term "colonization" is sometimes used synonymously with the word "settlement".

Settler colonialism is a type of colonization structured and enforced by the settlers directly, while their or their ancestors' metropolitan country (metropole) maintains a connection or control through the settler's activities. In settler colonization, a minority group rules either through the assimilation or oppression of the existing inhabitants, or by establishing itself as the demographic majority through driving away, displacing or outright killing the existing people, as well as through immigration and births of metropolitan as well as other settlers. Karl T. Muth notes in The Oxford Handbook of Global Policy and Transnational Administration that "Under the colonial framework, the administrative functions of government are partitioned according to the political convenience (and, often, economic interest) of the parent state rather than at the behest of the colony's residents."

The European colonization of Australia, New Zealand, and other places in Oceania was fueled by explorers, and colonists often regarding the encountered landmasses as ("empty land", or literally "nobody's land" in Latin). This resulted in laws and ideas such as Mexico's 1824 General Colonization Law and the United States' manifest destiny doctrine which furthered colonization.

Etymology The term colonization is derived from the Latin words ("to cultivate, to till"), ("a landed estate", "a farm") and ("a tiller of the soil", "a farmer"), then by extension "to inhabit". Someone who engages in colonization, i.e. the agent noun, is referred to as a colonizer, while the person who gets colonized, i.e. the object of the agent noun or absolutive, is referred to as a colonizee,Riordan, John P.

Pre-modern colonization

Classical period

In ancient times, maritime nations such as the city-states of Greece and Phoenicia established colonies in other parts of the Mediterranean.

Another period of colonization in ancient times was during the Roman Empire. The Roman Empire conquered large parts of Western Europe, North Africa, and West Asia. In North Africa and West Asia, the Romans often conquered what they regarded as 'civilized' peoples. As they moved north into Europe, they mostly encountered rural peoples/tribes with very little in the way of cities. In these areas, waves of Roman colonization often followed the conquest of the areas. Many of the current cities throughout Europe began as Roman colonies, such as Cologne, Germany, originally called Colonia Claudia Ara Agrippinensium by the Romans, and the British capital city of London, which the Romans founded as Londinium.

Middle Ages The decline and collapse of the Roman Empire saw (and was partly caused by) the large-scale movement of people in Eastern Europe and Asia. This is largely seen as beginning with nomadic horsemen from Asia (specifically the Huns) moving into the richer pasture land to the west, thus forcing the local people there to move further west and so on until eventually the Goths were forced to cross into the Roman Empire, resulting in continuous war with Rome which played a major role in the fall of the Roman Empire. During this period there were large-scale movements of people establishing new colonies all over western Europe. The events of this time saw the development of many of the modern-day nations of Europe like the Franks in France and Germany and the Anglo-Saxons in England.

In West Asia, during the reign of the Sassanid Empire, some Persians established colonies in Yemen and Oman. The Arabs also established colonies in Northern Africa, Mesopotamia, and the Levant.Pact Of UmaSelect Spread Of Islam, The"At the Prophet's death, according to the Muslim historians, the religion that he had brought was still confined to parts of the Arabian Peninsula. The Arabs, to whom he had brought it, were similarly restricted, with perhaps some extension in the borderlands of the Fertile Crescent. The vast lands in southwest Asia, northern Africa, and elsewhere, which in later times came to constitute the lands of Islam, the realms of the caliphs and, in modern parlance, the Arab world, still spoke other languages, professed other religions, and obeyed other rulers. Within little more than a century after the Prophet's death, the whole area had been transformed, in what was surely one of the swiftest and most dramatic changes in the whole of human history. By the late seventh century, the outside world attests the emergence of a new religion and a new power, the Muslim empire of the caliphs, extending eastward in Asia as far as and sometimes beyond the borders of India and China, westwards along the southern Mediterranean coast to the Atlantic, southwards towards the land of the black peoples in Africa, northwards into the lands of the white peoples of Europe. In this empire, Islam was the state religion, and the Arabic language was rapidly displacing others to become the principal medium public life." Lewis, Bernard. THE MIDDLE EAST: A Brief History of the Last 2,000 Years, Touchstone Simon and Schuster, New York, 1995. pp 54-55

The Vikings of Scandinavia also carried out a large-scale colonization. The Vikings are best known as raiders, setting out from their original homelands in Denmark, southern Norway, and southern Sweden, to pillage the coastlines of northern Europe. In time, the Vikings began trading and established colonies. The Vikings first came across Iceland and established colonies there before moving onto Greenland, where they built settlements that endured until the 15th century. The Vikings launched an unsuccessful attempt at colonizing an area they called Vinland, which is probably at a site now known as L'Anse aux Meadows, Newfoundland and Labrador, on the eastern coastline of Canada.

Colonial era

In the colonial era, colonialism in this context refers mostly to Western European countries' colonization of lands mainly in the Americas, Africa, Asia, and Oceania. The main European countries active in this form of colonization included Spain, Portugal, France, the Tsardom of Russia (later Russian Empire), the Kingdom of England (later Great Britain), the Netherlands, the Kingdom of Italy, the Kingdom of Prussia (now mostly Germany), Belgium, Denmark, and Sweden-Norway, and, beginning in the 18th century, the United States. Most of these countries had a period of almost complete power in world trade at some stage in the period from roughly 1500 to 1900. Beginning in the late 19th century, the Empire of Japan also engaged in settler colonization, most notably in Hokkaido and Korea.

While some European colonization focused on shorter-term exploitation of economic opportunities (Newfoundland, for example, or Siberia) or addressed specific goals such as settlers seeking religious freedom (Massachusetts), at other times long-term social and economic planning was involved for both parties, but more on the colonizing countries themselves, based on elaborate theory-building (note James Oglethorpe's Colony of Georgia in the 1730s and Edward Gibbon Wakefield's New Zealand Company in the 1840s).

Colonization may be used as a method of absorbing and assimilating foreign people into the culture of the imperial country. One instrument to this end is linguistic imperialism, or the use of non-indigenous colonial languages to the exclusion of any indigenous languages from administrative (and often, any public) use.

20th–21st century on Earth

Soviet Union

In the 1920s, the Soviet regime implemented the so-called korenizatsiia policy in an attempt to win the trust of non-Russians by promoting their ethnic cultures and establishing for them many of the characteristic institutional forms of the nation-state. The early Soviet regime was hostile to even voluntary assimilation, and tried to de-Russify assimilated non-Russians. Parents and students not interested in the promotion of their national languages were labeled as displaying "abnormal attitudes". The authorities concluded that minorities unaware of their ethnicities had to be subjected to Belarusization, Polonization, etc.

By the early 1930s, the Soviet government introduced limited Russification; allowing voluntary assimilation, which was often a popular demand. The list of nationalities was reduced from 172 in 1927 to 98 in 1939, by revoking support for small nations in order to merge them into bigger ones. Russians were now presented as the most advanced and least chauvinist people of the Soviet Union.

The Soviet control of Königsberg area of East Prussia (modern Kaliningrad Oblast), given to the Soviet Union at the 1945 Potsdam Conference, meant a forcible expulsion of the remaining German population and mostly involuntary resettlement of the area with Soviet civilians.

Baltic states

Large numbers of ethnic Russians and other Russian speakers were settled in the three Baltic countries – Lithuania, Latvia, and Estonia – after their reoccupation in 1944, while local languages, religion and customs were suppressed. David Chioni Moore classified it as a "reverse-cultural colonization", where the colonized perceived the colonizers as culturally inferior. Colonization of the three Baltic countries was closely tied to mass executions, deportations and repression of the native population. During both Soviet occupations (1940–1941; 1944–1991) a combined 605,000 inhabitants of the three countries were either killed or deported (135,000 Estonians, 170,000 Latvians and 320,000 Lithuanians), while their properties and personal belongings, along with ones who fled the country, were confiscated and given to the arriving colonists – Soviet military and NKVD personnel, as well as functionaries of the Communist Party and economic migrants from kolkhozes.

The most dramatic case was Latvia, where the amount of ethnic Russians swelled from 168,300 (8.8%) in 1935 to 905,500 (34%) in 1989, whereas the proportion of ethnic Latvians fell from 77% in 1935 to 52% in 1989. Baltic states also faced intense economic exploitation, with Latvian SSR, for example, transferring 15.961 billion rubles (or 18.8% percent of its total revenue of 85 billion rubles) more to the USSR budget from 1946 to 1990 than it received back. And of the money transferred back, a disproportionate amount was spent on the region's militarization and funding of repressive institutions, especially in the early years of the occupation. It has been calculated by a Latvian state-funded commission that the Soviet occupation cost the economy of Latvia a total of 185 billion euros.
