When the Great Song Fled to America – China Alternate History Mod

The original idea was "Song-in-Australia" — an alternate history where the Song court fled to Australia after its defeat. But this would have prematurely involved the late-Yuan Red Turban Rebellion, diluting the feeling of "a group of companions who fled the Central Plain together." So the idea was changed, drawing on the well-known EU4 alternate-history mod Third Odyssey, and rebuilding the exiled Song state on the American West Coast instead.

This mod was made with the help of Codex and Claude Code. Full bug testing has not yet been done (only partial testing so far), including but not limited to: whether the Mandate of Heaven claim against the Celestial Empire works correctly, whether event chains trigger reliably, and whether some laws and innovations have balance or triggering issues. Feedback and comments are welcome.

The court believed the tribes had fallen silent out of fear — never knowing that it was the unbroken line of fortress-towns beneath the crimson banners that, for the first time, made them feel they belonged to a single realm.

Hai Song’s stage now crosses the coastline, pressing deep into the new continent men call the Silent Land. And it is anything but silent.

Several playable Native American empires — along with the vassal marches under Ming-Song rule — become available. The same frontier pressure gives rise to six utterly different kinds of state across the Great Plains, the Northwest Coast, the Mississippi, Mexico, the Andes, and the Eastern Woodlands — each with its own event chain, including, but not limited to, the campaign that can rewrite everything: the natives breaching the Pass.

The denser your forts, the more land you seize, the more horses and firearms you sell — the faster the tribes unite, and the stronger your nemesis grows. Yet should Ming-Song itself decline, the shadow empire sustained by your tribute may unravel with it. The tribes were never one people by nature — it was you who first made them realize they belonged to a single realm.

Frontier pressure will be built into a redesigned Court SubUI, with a substantially reworked presentation — and the frontier empires, too, will each have their own version of the interface.

And should that day come at last — the cities laid to ruin, the topknots shorn, the right-fold robes turned to the left —
A realm may fall, yet its record shall not; a people may perish, yet its heart shall not.
Where now is the Heart-History of Suonan? The answer awaits.
