skipped an archetype like time before last?

The Glorious Revolution itself was a Mega-Unraveling 4T. The real question is does the cold civil war stay cold like then or does it go hot at some point. That remains to be seen. If it stays cold the 1T will open with both sides exhausted. If it goes hot I would expect one side to establish a new order for the Mega-Crisis (which is a whole saeculum itself with its component turnings) so repugnant as to set the stage for the next 4T to be a complete bloodbath.

The Last Mega-Crisis saeculum was the Enlightenment Saeculum. (Sometimes called the Revolutionary Saeculum but I'm not so America Centeric) That cold-civil war lead to the French Revolution and the Napoleonic wars. This scared Europe for a century, and they moved their conflicts to the colonies afterward to avoid bloodbaths in the metropolitan areas. However, without that the current order wouldn't have arrisen because it set the stage for WW1 in the 3T of the Mega-Awakening, and the establishment of two main political philosphies to duke it out most of the Mega-Unraveling. In our case Liberal Democracy (Liberal in the classical sense and not in the absurd 'Progressive' sense most Americans misuse that word) vs Communism. But it could have been as easily Liberal Democracy vs Fascism, or even Bismarkian Monarchism.
