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

). 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.

and Ryan Griffiths link increased numbers of secessions to an international system that is more favorable for new states. For example, new states can obtain assistance from international organizations such as the

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,

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

Nonetheless, the 2003 draft of the European Union Constitution allowed for the voluntary withdrawal of member states from the union, although the representatives of the member-state which wanted to leave could not participate in the withdrawal discussions of the European Council or of the Council of Ministers. There was much discussion about such self-determination by minorities before the final document underwent the unsuccessful ratification process in 2005. In 2007 the Treaty on European Union included Article 50 of the Treaty on European Union, establishing a mechanism for withdrawal from the EU.

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".

Italy

The Movement for the Independence of Sicily (Movimento Indipendentista Siciliano, MIS) has its roots in the Sicilian Independence Movement of the late 1940s; it was active for around 60 years. Today, the MIS no longer exists, though many other parties have emerged.

The reality today is that although South Islanders have a strong identity rooted in their geographic region, secession does not carry any real constituency; the party was not able to field any candidates in the 2008 election, as they had less than 500 paying members, a requirement by the New Zealand Electoral commission. The party is treated more as a "joke" party than any real political force.

South Sudan

A referendum took place in Southern Sudan from 9to 15 January 2011, on whether the region should remain a part of Sudan or become independent. The referendum was one of the consequences of the 2005 Naivasha Agreement between the Khartoum central government and the Sudan People's Liberation Army/Movement (SPLA/M). On 7 February 2011, the referendum commission published the final results, with 98.83% voting in favour of independence. While the ballots were suspended in 10 of the 79 counties for exceeding 100% of the voter turnout, the number of votes was still well over the requirement of 60% turnout, and the majority vote for secession is not in question. A simultaneous referendum was supposed to be held in Abyei on whether to join Southern Sudan but it has been postponed because of conflict over demarcation and residency rights. In October 2013, a symbolic referendum was held in which 99.9% of voters in Abyei voted to join Southern Sudan. However, this resolution was non-binding. As of February 2024, an official referendum still has not taken place. Abyei currently holds "special administrative status". The predetermined date for the creation of an independent state was 9July 2011.
