Internal colonialism

Internal colonialism is the uneven effects of economic development on a regional basis, otherwise known as "uneven development" as a result of the exploitation of minority groups within a wider society and leading to political and economic inequalities between regions within a state. This is held to be similar to the relationship between metropole and colony, in colonialism proper. The phenomenon creates a distinct separation of the dominant core from the periphery in an empire. 
Robert Blauner is regarded as the developer of the theory of internal colonialism. The term was coined to highlight the "blurred" lines between geographically close locations that are clearly different in terms of culture. Some other factors that separate the core from the periphery are language, religion, physical appearance, types and levels of technology, and sexual behaviour. The cultural and integrative nature of internal colonialism is understood as a project of modernity and has been explored by Robert Peckham in relation to the formation of a national modern Greek culture during the nineteenth century, when Greece gained independence from the Ottoman Empire.
The main difference between neocolonialism and internal colonialism is the source of exploitation. In the former, the control comes from outside the nation-state, while in the latter it comes from within. 
Origin of the concept.
The first known use of the concept of internal colonialism was by regarding South Africa. However, the concept became popularized following the publication of an article on Mexico by . Gonzalez Casanova was both critiqued by, and influenced Andre Gunder Frank, who further theorised internal colonialism as a form of "uneven development". Sergio Salvi, a poet, essayist, and historian of minority languages, used the term "internal colonies" in the cultural sense in "Le nazioni proibite: Guida a dieci colonie interne dell'Europa occidentale" ("The forbidden nations: Guide to ten internal colonies of western Europe") (1973), among which he included Catalonia, Scotland, Brittany and Occitania. Other pivotal works on the subject were published during the mid-1970s by Harold Wolpe and Michael Hechter. Adolf Hitler mentions the concept of Internal colonization in his book Mein Kampf of 1925, chapter 4, as a wrong way of tackling the problems that come with the increase of population of a nation. He states that "The limitation to a definite small area of soil, inherent in internal colonization... leads to an exceedingly unfavorable politicomilitary situation in the nation in question."
Examples.
A common topic amongst postcolonial writers was their description of feelings, such as schizophrenia, being torn between local tradition and global modernity.
Afghanistan.
Afghanistan is an example of internal colonialism affecting state-building, as M Nazif Sharani argues "the incessantly centralizing state policies and practices of internal colonialism, generally aided and abetted by old colonialist powers... produced a cumulatively negative impact on state-building efforts in Afghanistan." The international security scholar, Dipali Mukhopadhyay, considers the presence of warlordism in the Afghan periphery to be a concern for the development of the political economy, with the 2007 World Bank Report highlighting weak institutional links between provincial offices and relationships with the central government poorly defined.
Algeria.
One of the exceptions of internal colonialism as the subsistence of 'blurred lines' between the core and periphery is French Algeria. There were clearly distinct features separating the core from the periphery. "The core was Christian, French-speaking, light-skinned, and comparatively prosperous". The other side was Muslim, Arabic/ Berber-speaking, and significantly poorer. The grey section of French Algeria, was the large Jewish population which did not belong in either the core or periphery, in terms of common cultural factors.
Baltic states.
In the mid-twentieth century, the Soviet-occupied countries of Estonia, Latvia, and Lithuania had a colonial relationship with the rest of the Soviet Union, similar to the one that existed between the old tsarist empire and its far-flung territories. Although the countries were gradually being Sovietized after their period of initial resistance, the newly established economic, cultural, and social circumstances were colonial, as the reconstruction of the economy in the region served the interests of the colonizers, identities became shaped in relation to the increasing Soviet presence, the experience of oppression became an increasingly important part of the local culture, and local historical and cultural heritage was revalued and rewritten. When the Soviet Union dissolved and the Baltic states became independent once again, they had to deal with problems similar to other postcolonial nations: polluted landscapes, damaged economies, ethnic tensions, and determining the national narrative of the past, present and future. 
Canada.
 documents the internal colonialism of Western Canadian Provinces by Central Canada, citing issues with the National Energy Program, the Crow Rate, and Equalization payments in Canada amongst others.
Ireland.
An example of internal colonialism is Ireland. Ireland was formerly a part of the United Kingdom and "...was far more common and apparently easier, to think of oneself as British "and" Irish". It was increasingly more difficult to choose between the two.
Philippines.
In the Philippines, non-Manilans have often expressed that the affairs of the country—whether political, economic but most importantly cultural including linguistic—are imposed from the Manilan core on the peripheral rest of the country due to Tagalist nationalism. This has been articulated in a Cebuano saying, which goes, "Walay dahong mahulog sa atong nasod nga dili mananghid sa Malakanyang," translated as "Not a leaf may fall in our country without Malacañang's permission." It is also ominous that certain personalities have called for the political isolation, overthrow and outright assassination of those who are opposed to the current core–periphery relationship.
Sri Lanka.
Sri Lanka is a very good example of internal colonialism:
International Dimensions of the Ethnic Conflict in Sri Lanka, Prof John P. Neelsen (Tuebingen University, Germany), 20th European Conference on Modern South Asian Studies, 8–11 July 2008: "A shortcoming in international law as to internal colonialism and the right to self-determination renders the current types of international intervention not just inadequate to contribute to a negotiated solution of ethnic conflicts, but tends to inflame them."
Power Sharing as Peace Structure: The Case of Sri Lanka, IICP Working Paper, No. 2, 2005, Johan Galtung, Professor of Peace Studies: ‘’External Colonialism: Democracy :: Internal Colonialism: Human Rights’’
National Liberation Movements in Global Context, Dr. Jeff Sluka, Massey University, New Zealand 
Proceedings of the Conference on 'Tamils in New Zealand', July 1996 - Wellington, New Zealand. 
This situation, where a state exploits and oppresses peoples and regions within their own boundaries much the way the European colonial powers used to exploit and oppress foreign colonies, has been described as "internal colonialism". Sri Lanka is an example of this. Many Third World peoples found that after "independence" they had simply traded one set of oppressors (white) for another (brown and black). The result is that today many Third World states, most of them the direct or indirect result of national liberation wars themselves, are now fighting against national liberation movements within their borders.
Fourth World Colonialism, Indigenous Minorities And Tamil Separatism In Sri Lanka, Bryan Pfaffenberger (Virginia University), Bulletin of Concerned Asian Scholars, Vol. 16, 1984:
"Despite the withdrawal of colonial power from Third World countries, forms of oppression that might well be termed "colonial" still persist in many of them — the oppression wrought by nationalist Third World governments whose regimes fail to respect the rights of indigenous minorities. For ethnic and regional minorities in many Third World countries, the arrogance and injustice of these governments matches — and often exceeds — those of the departed European colonial regime. The island nation Sri Lanka presents a case in point. Little public investment appears to reach the Tamil lands…."
Thailand.
For internal colonization in the kingdom of Thailand, refer to articles on Monthon and on Thaification. There is a posited link between internal colonialism and ethnic rebellion in Thailand.
Turkey.
The internal colonization of the Eastern Provinces was outlined during the Government of Mustafa Kemal Atatürk. Cemil Uyabdin saw the Report for Reform in the East as a guideline to the internal colonization of the Eastern Provinces through which the Kurdish population should be turkified. In a report delivered to the Republican Peoples Party (CHP) following the defeat of the Dersim Rebellion, the Resettlement Law issued in 1934 was also described as an effective vehicle for the internal colonization of the eastern provinces.
China.
China has a history of colonialism and genocide against its ethnic minorities, such as the Uighurs and Tibetans. Tibet, having been a self governed province in China, has been completely annexed by China since 1949 with 1.2 million Tibetans being estimated to have been killed since. Since the occupation, China has reportedly been accused of both genocide and cultural genocide, having made Chinese the dominant language in Tibet as an example. Over 100,000 Tibetans now live in exile in India, including their former leader.
