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. Proto-states established as a result of civil conflict typically exist in a perpetual state of warfare and their wealth and populations may be limited accordingly. One of the most prominent examples of a wartime proto-state in the twenty-first century is the Islamic State of Iraq and the Levant, that maintained its own administrative bureaucracy and imposed taxes.
