at the water's edge
Historically, the term "secessionist" is used more often to describe the losing Confederate side in the American Civil War or the War to Preserve Slavery. The present day supporters of the losers of that conflict are also known as the proponents of the Lost Cause of the South. During the Civil War era in America the secessionists were known as "seceshers" and are called such today. Modern era seceshers in the U. S. may include both Southerners (or as they're known to call themselves, "Southroners") and Northerners. All are afflicted by the "false-consensus effect" whereby they overestimate the importance and the popularity of their endeavor.
Even in America, it's not quite dead.
A common historical misrepresentation made by today's small community of active secession advocates is that the U.S. and other colonies were born by an act of secession. While in some sense this is true, the term session implies the leaving of a body you are an integral part of, while a colony, with some exceptions, is a subservient territory under the rule of another country.
Today no country officially considers any part of its territory to be a "colony" and as such independence movements of e.g. Caribbean islands belonging to some European power would be labeled "secessionist" by proponents of their mother country, even though they would describe themselves as anti-colonialist. And that's all we are going to say about that.[citation NOT needed]
Some notable cases of secession politics in the last century or so:
- Algeria, a colony so important to France that they even directly annexed it as initially 3 and later 17 departments.
- Abkhazia, from Georgia (with help from Russia)
- Bangladesh, from Pakistan (with help from India)
- Chechnya, from Russia between 1994 and 1999/2000. (the wars for its secession played a major role in the career of one certain V. Putin)
- Crimea, from Ukraine (annexed by Russia)
- Eritrea, from Ethiopia
- Greenland from the European Community, prior to that one becoming the European Union - they are still part of the Kingdom of Denmark as one of its "constituent countries" though. The secession was mostly due to fishery quotas.
- Ireland, from the UK
- Kosovo, from Serbia (with help from NATO)
- Montenegro, from Serbia and Montenegro, the entity "rest-Yugoslavia" was renamed too
- Nagorno-Karabakh, from Azerbaijan (de facto independent with intention to join Armenia)
- Novorossiya (Donetsk Peoples Republic/ Lugansk Peoples Republic), from Ukraine (with help from Russia)
- Panama, from Colombia (with help from the US)
- Singapore, from Malaysia
- Somaliland, from Somalia (not recognized by any UN member state, but de facto independent)
- South Sudan, from Sudan
- South Ossetia de facto (officially recognized only by Russia, Nicaragua and a couple of Pacific islands), from Georgia (with help from Russia)
- Timor-Leste, from Indonesia
- Transnistria de facto (not officially recognized by any other country), from Moldova (with help from Russia)
- Turkish Republic of Northern Cyprus de facto (recognized by no country other than Turkey), from Cyprus (with help from Turkey)
- West Virginia, from Virginia (rather uniquely, part of a state which seceded from the United States, seceded back to the United States)
- All 15 nations that used to be part of the Soviet Union
- Pretty much everybody from Yugoslavia.
- All of the nations that made up Austria-Hungary
Fairly popular from the dawn of Humanity to the recent past, unilateral attempts at secession were both common and bloody whether successful or not.
- Anjouan, from Comoros
- Azawad, from Mali
- Biafra, from Nigeria - briefly achieved de facto independence before being crushed after three years of war by Nigeria
- Bougainville, from Papua New Guinea
- Cabinda, from Angola
- Casamance, from Senegal
- Chechnya, from Russia after 2000 and the second Chechnya War (the wars for its secession - which it briefly de facto achieved - played a major role in the career of one certain V. Putin)
- Dagestan, from Russia (de facto independent in 1999)
- Far Eastern Republic, from Russia - also most of what became Union Republics in the European part of the USSR, during the Russian Civil War
- Katanga, from the Democratic Republic of the Congo
- Kurdistan, from Iran, Iraq (de facto from 1990 to 2003), Syria (de facto in Rojava), and Turkey
- Manchukuo, from China (though it was a puppet of Imperial Japan)
- Mohéli, from Comoros
- Northern Ireland, from the UK during the Troubles.
- South Maluku, from Indonesia (de facto independent in 1950)
- South Yemen, following union with Yemen in 1990
- Tamil Eelam, from Sri Lanka
- Tibet, from China
- Western Sahara - from the - not internationally recognized - Moroccan occupation (despite a small part of the claimed territory being actually under de facto control of the pro-independence Polisario)
- West Papua, from Indonesia
- Zanzibar, from Tanzania
- 11 southern states in the mid-1800's from the United States as the CSA. Fought a war for the majority of its existence that they then lost. De jure unrecognized by any of the Great Powers despite many attempts, and the official US position decided by legal decisions afterwards is that they never actually seceded in the first place.  Today secessionist sentiment is exploited - and sometimes fueled - by Republican politicians, of all people.
Unsuccessful Peaceful Attempts
- Catalonia, from Spain (though this may change after the separatists won narrowly in the 2015 elections)
- Quebec, from Canada (see Bloc Québécois).
- Scotland, from the UK (see Scottish National Party). Attempted once in 2014 and lost by 10% of a vote. Likely to try again.
- Aceh Region, from Indonesia (though they have gained autonomy)
- Åland, from Finland (though they have a high degree of autonomy)
- Assam, from India
- Balochistan, from Pakistan
- Basque Country, from Spain (and possibly France) (though they have a high degree of autonomy guaranteed by the Spanish constitution)
- Bavaria, from Germany - the Bayernpartei is the last one to openly advocate it, although the CSU sometimes at least wags a middle finger at Berlin - despite being officially unionist.
- Brittany, from France
- Catalonia, from Spain. An independence referendum, albeit illegal, was successfully held there, and there is a serious likelihood of future autonomy of some kind.
- Cornwall, from England (see Mebyon Kernow)
- Corsica, from France
- East Turkestan (Xinjiang), from China
- Faroe Islands, from Denmark (though they have a high degree of autonomy as a "constituent country" of the Kingdom of Denmark)
- Flanders, from Belgium
- Franconia, from Bavaria (especially if the latter's secession from Germany is successful)
- Galicia, from Spain (possibly to join with Portugal)
- Greenland, from Denmark (of which they currently are a constituent country).
- Inner Mongolia, from China (possibly with intention to unify with "Outer" Mongolia)
- Islamic State, from the Middle Eastern post-colonial setup. While this may not qualify as a secessionist movement per se (as ISIS would love to conquer all of these countries, rather than simply secede), it has been pretty successful so far at carving out a piece of land and holding de facto control over varying parts of it for years.
- Jammu and Kashmir, from either Pakistan or India in order to join the other
- Karelia, from Russia
- Khalistan (Punjab region), from both Pakistan and India
- Kurdistan, from Turkey, Syria, Iraq, and Iran. Iraqi Kurdistan is de jure recognized by the government as autonomous and they were de facto independent from Saddam between the two American invasions of Iraq, and Rojava in Syria is de facto, being an 'autonomous confederation' separate from all other entities there. Kurdish regions in Iran and Turkey want to separate, but both are mostly held by the host governments, with exceptions in Turkey.
- Manipur, from India
- New Caledonia, from France
- Northern Italy, from Italy
- "Venetia" (the area surrounding Venice) from Italy
- Puerto Rico, from the US (possibly with the intention of joining a free association agreement with US)
- Republika Srpska, from Bosnia
- Ryukyu Islands, from Japan
- Sicily, from Italy
- South Tyrol, from Italy (possibly with the intention of becoming part of Austria)
- The Taiwanese Independence movement from the Republic of China. Unique in that the country it would break away from would cease to exist as they cover the same territory and that it is the political goal of one of the two main party blocs in Parliament. This would also potentially spark an invasion by the Mainland, who see Taiwan as belonging to it, just under rebel occupation (the reverse is true from the point of view of the ROC). Interestingly enough a Taiwanese separatist movement already existed during and prior to Japanese occupation (1895-1945). In fact a very short-lived Republic of Formosa existed briefly during 1895.
- Tripura, from India
- The United Kingdom, from Europe/the European Union. See UKIP
- The Upper Peninsula, from Michigan (with the intention to become the State of Superior)
- Wales, from the UK (see Plaid Cymru)
- Wallonia, from Belgium
- Yorkshire from the UK, ranging from movements for greater autonomy or devolution to full independence, although the latter is widely considered a joke.
- various states from the US
In the US
From US Independence it was unclear whether a constituent state could legitimately bail out of the United States, until the 1869 decision in Texas v. White ruled that the US Constitution prevented states from seceding unilaterally from the union. Both before and after that decision, various secessionist movements have sprung into existence. The most famous was that which led to the American Civil War, but aside from that there have been many other less violent and more comical examples, ranging from self-proclaimed micronations to proposals for the largest states.
There have also been independence movements in various US territories such as Puerto Rico, but they tend to be more rational. In addition, there are various proposals for counties or parts of states to secede from their existing state and form a new state still within the US; this is enormously trivial and not covered here (examples: eastern Washington State, northern Maine, southern California, far northern California and southern Oregon, southern Arizona, New York City).
Joe Vogler founded Alaskans for Independence and the Alaskan Independence Party in 1973, 14 years after Alaskan statehood (Alaska became a state in 1959). Initially he focused on a petition calling for secession. The party was officially recognised in 1984. An attempt to hold a vote on a ballot initiative for secession was proposed in 2006, but despite receiving the required number of signatures was ruled unconstitutional and removed from the ballot. Since then the party has moved away from secessionism, adopting a libertarian platform similar to lots of other minor parties (Constitution Party, Libertarian Party, etc). Todd Palin, Sarah Palin's husband, was a member for a while.
California has often been viewed as somewhat separate to the majority of the US, but the California National Party was only founded in 2015. Following the election of Donald Trump in November 2016, there were calls for CalExit (funded in part by the Anti-Globalization Movement of Russia), i.e. Californian secession, and even proposals to join Canada.
Geographically, Hawaii is detached from the continental US, and it was an independent state for many years. Even today there are those who seek independence, mainly native Hawaiians. Some organisations want the restoration of the Hawaiian monarchy, while others such as the Nation of Hawai'i have called for an independent republic.
Similar to the Second Vermont Republic, there is an effort to get Christian fundamentalists to move to Maine and establish an independent Republic of Maine, which will ban shops from opening on Sundays.
Texas was independent from 1836 to 1845, when it joined the US. Since then, a small subset of Texans have regretted that decision. Texas attempted to secede in 1861 following a referendum, but Abraham Lincoln managed to change their minds after only a little war. There was uncertainty about Texas's status for a while afterwards, but things quieted down for over a hundred years. In the 1990s a renewed secessionist movement began, with such groups as Richard Lance McLaren's Republic of Texas organization and its more moderate offshoot, Daniel Miller's Texas Nationalist Movement. McLaren became increasingly eccentric, demanding 93 trillion dollars in reparations from the US federal government and taking hostages in an armed siege which led to him being sentenced to 99 years in jail, although fortunately there were no deaths.
Texas governor Rick Perry hinted at secession in 2009, and following Barack Obama's second victory in 2012, there was even more widespread interest in secession, though the majority of Texans declared themselves opposed. Texans' calls for independence are often met in the rest of the country with responses that amount to "Don't let the door hit you on the way out."
- This also the reason why Norway and Iceland are unlikely to join the EU any time soon. Iceland even got to "war" with the Royal Navy over fishing. see here for details on one of the most bizarre wars in history - won by the nation without an army to boot.
- To wit: Slovenia, Croatia, Bosnia&Herzegovina, Macedonia and - at a later stage - Montenegro (by than the name had already changed away from Yugoslavia)
