Secession is the formal withdrawal of a group from a
political entity. The process begins once a group proclaims an act of secession (such as a
declaration of independence
A declaration of independence is an assertion by a polity in a defined territory that it is independent and constitutes a state. Such places are usually declared from part or all of the territory of another state or failed state, or are breaka ...
). A secession attempt might be violent or peaceful, but the goal is the creation of a new state or entity independent of the group or territory from which it seceded.
Threats of secession can be a strategy for achieving more limited goals.

Secession theory
There is no consensus on the definition of political secession despite many political theories on the subject.
According to the 2017 book ''Secession and Security,'' by political scientist
Ahsan Butt, states respond violently to secessionist movements if the potential state poses a greater threat than the would-be secessionist movement.
States perceive a future war with a potential new state as likely if the ethnic group driving the secessionist struggle has deep identity division with the central state, and if the regional neighborhood is violent and unstable.
Explanations for the 20th century increase in secessionism
According to political scientist Bridget L. Coggins, the academic literature contains four potential explanations for the drastic increase in secessions during the 20th century:
* Ethnonational mobilization, where ethnic minorities have been increasingly mobilized to pursue states of their own.
* Institutional empowerment, where the growing inability of empires and ethnic federations to maintain colonies and member states increases the likelihood of success.
* Relative strength, where increasingly powerful secessionist movements are more likely to achieve statehood.
* Negotiated consent, where home states and the international community increasingly consent to secessionist demands.
Other scholars have linked secession to resource discoveries and extraction. David B. Carter, H. E. Goemans, and Ryan Griffiths find that border changes among states tend to conform to the borders of previous administrative units.
Several scholars argue that changes in the international system have made it easier for small states to survive and prosper.

classification of the literature on secession. In his 1991 book ''Secession: The Morality of Political Divorce From Fort Sumter to Lithuania and Quebec'', Buchanan outlined limited rights to secession under certain circumstances, mostly related to oppression by people of other ethnic or racial groups, and especially those previously conquered by other people.
[Allen Buchanan, ''Secession: The Morality of Political Divorce From Fort Sumter to Lithuania and Quebec'', West View Press, 1991.] In his collection of essays from secession scholars, ''Secession, State, and Liberty'', professor David Gordon challenges Buchanan, making a case that the moral status of the seceding state is unrelated to the issue of secession itself.
Justifications for secession
Some theories of secession emphasize a general right of secession for any reason ("Choice Theory") while others emphasize that secession should be considered only to rectify grave injustices ("Just Cause Theory"). Some theories do both. A list of justifications may be presented supporting the right to secede, as described by Allen Buchanan, Robert McGee,

'' right to secede.
* Cultural Secessionism: any group which was previously in a minority has a right to protect and develop its own culture and distinct national identity through seceding into an independent state.
* The Secessionism of Threatened Cultures: if a minority culture is threatened within a state that has a majority culture, the minority needs a right to form a state of its own which would protect its culture.
Arguments against secession
Allen Buchanan, who supports secession under limited circumstances, lists arguments that might be used against secession:
* "Protecting legitimate expectations" of those who now occupy territory claimed by secessionists, even in cases where that land was stolen
* "Self defense" if losing part of the state would make it difficult to defend the rest of it
* "Protecting majority rule" and the principle that minorities must abide by them
* "Minimization of strategic bargaining" by making it difficult to secede, such as by imposing an exit tax
* "Soft paternalism" because secession will be bad for secessionists or others
* "Threat of anarchy" because smaller and smaller entities may choose to secede until there is chaos, although this is not the true meaning of the political and philosophical concept
* "Preventing wrongful taking" such as the state's previous investment in infrastructure
* "Distributive justice" arguments posit that wealthier areas cannot secede from poorer ones

or the independent Republic of Cameroon as a federation of two equal states. While the Northern Cameroons voted to join Nigeria, the Southern Cameroons voted to integrate into the Republic of Cameroon, but they did so without a formal Treaty of Union on record at the UN. In 1972, Cameroon used its majority population to abolish the federation and implement a system which resulted in the occupation of the former South Cameroons territory by French-speaking Cameroon administrators. In 1984, Cameroon heightened tensions by returning to its name at independence, "Republic of Cameroun", which did not include the territory of the former British Southern Cameroons or Ambazonia.
For more than fifty years the English-speaking people of the Former British Southern Cameroons made multiple attempts both nationally and internationally to get the Cameroon government to address these issues and possibly return to the previously agreed federation at independence. In 2016, after all these attempts failed, Cameroon engaged in a military crackdown, including cutting the internet in the English-speaking regions. In response, the people of Southern Cameroon declared on October 1, 2017, the restoration of their UN state of Southern Cameroons, which they called the " Federal Republic of Ambazonia".
