Quasi-state

[4] In the 21st century usage, the term quasi-state has most often been evoked in reference to militant secessionist groups who claim, and exercise some form of territorial control over, a specific region, but which lack institutional cohesion.

[12] For instance, historical sociologist Garry Runciman describes the evolution of social organisation in the Greek Dark Ages from statelessness, to what he calls semistates based on patriarchal domination but lacking inherent potential to achieve the requirements for statehood, sometimes transitioning into protostates with governmental roles able to maintain themselves generationally, which could evolve into larger, more centralised entities fulfilling the requirements of statehood by 700 BC in the archaic period.

[12][13] Most ancient proto-states were the product of tribal societies, consisting of relatively short-lived confederations of communities that united under a single warlord or chieftain endowed with symbolic authority and military rank.

[5][4][20] Another form of proto-state that has become especially common since the end of World War II[citation needed] is established through the unconstitutional seizure of territory by an insurgent or militant group that proceeds to assume the role of a de facto government.

[9] Although denied recognition and bereft of civil institutions, insurgent proto-states may engage in external trade, provide social services, and even undertake limited diplomatic activity.

[9] The accumulation of territory by an insurgent force to form a sub-national geopolitical system and eventually, a proto-state, was a calculated process in China during the Chinese Civil War that set a precedent for many similar attempts throughout the twentieth and twenty-first centuries.

[32] While not a new phenomenon, the modern formation of a proto-states in territory held by a militant non-state entity was popularised by Mao Zedong during the Chinese Civil War, and the national liberation movements worldwide that adopted his military philosophies.

[23] Secessionist proto-states are likeliest to form in preexisting states that lack secure boundaries, a concise and well-defined body of citizens, or a single sovereign power with a monopoly on the legitimate use of military force.

[33] They may be created as a result of putsches, insurrections, separatist political campaigns, foreign intervention, sectarian violence, civil war, and even the bloodless dissolution or division of the state.
