On identifying Ages, we sought to capture and represent general historical trends that were happening roughly around the same time period. But this isn't perfect, and one thing we didn't want to do was have the events of the Mediterranean dictate a calendar for the rest of the world. So if we were to summarize some general processes within each Age:
Antiquity is characterized by competition between states and non-state regions around them – the “blank spaces” on the map. It is a time of city-building, of universalism and expansion, where states claim a mantle of absolute authority. This is the time when states claim to represent the heavens, and that their language is the one true one.
Exploration is a time of vernacularization – when these prior empires split into fragments of the former whole, and where local innovations alter what was there before. It is a time when universal religions rise to suture this gap, but where interconnections – especially global interconnections – come to define states.
Modernity is a retrenchment of empire. Here, modern and scientific thought, bureaucracy, has replaced or fused with notions of divine right, and empires are increasingly seeking to understand, catalog, control, and apportion their subjects.
In that way, I made the pitch for the early Khmer as a better fit for Antiquity – early Khmer was continually expanding into non-state lands, the building and establishment of cities and the construction of a mandala state - a center-oriented city that sought to bring the cosmos into orbit around itself. In creating this gravitational/civilizational pull, Khmer cast itself as a universal center for civilization – something which resonates much more with Antiquity states elsewhere. In Southeast Asia, we can pretty clearly see a classical period of state formation (until 1100ish), a period of vernacular splintering and cosmopolitan early modern trade (around 1400), and the formation of modern nation-states (around 1820). Three ages - pretty nicely delineated... but the numbers here don't line up with Europe.
As this suggests, there are also excellent descendants in the region that are doing very Exploration Age related things
