Authoritarian power, wielded over populations, territory and resources, restricted by physical and political geography, dictates the “world order.” The present order is largely the product of hard-nosed geopolitics, but it also reflects the various attempts to impose a global order.
The struggle to manage and mitigate the consequences of geopolitics is evident in the history of international relations. For nearly 500 years nation-states have sought to co-exist as sovereign entities. Numerous systems have been devised to seize control of what would otherwise be anarchy. It is very much to the detriment of humanity that anarchy has not been allowed to flourish.
In 1648, the two bilateral treaties that formed the Peace of Westphalia concluded the 30 Years War (or Wars). Those negotiated settlements arguably established the precept of the territorial sovereignty within the borders of the nation-state.
This reduced, but did not end, the centralised authoritarian power of the Holy Roman Empire (HRE).
