The Union
The Thirteen Realms bound as a Holy American Empire, its High King elected and raised from among his peers. Strong in ideal, fragile in practice, and the prize every ambitious lord covets.

In American Kingdoms, American history is re-imagined as an Arthurian medieval epic – an age defined not by musket and cannon, but by knightly honor and courtly intrigue. This alt-history project is a collaborative worldbuilding effort: anyone can join our wiki to add their own character or fief to the strange but familiar setting of American Kingdoms. Join a medieval pastiche where the Natives fight on equal footing with conquistadores, and where Asian, European and American cultures clash for control of the New World.
“Thirteen hundred, four score and seven years ago, on this continent, a covenant was struck between a free people and their God.”
The year is 1377. After years of unrest, the Outremer Kingdoms of the eastern coast rise against their British overlords, igniting a rebellion that will engulf a continent.
As the perfidious Redcloaks are driven from American cities, thirteen sovereign dukes forge an audacious new order: a Union of equals, bound by charter and crowned as the Union of American Kingdoms. Its High King will reign not by birthright, but by the consent of his peers, elected from among them to defend the ancient liberties of the realm.
Part feudal compact, part republican experiment, this fragile Union promises freedom from the Old World. It may yet tear the New World apart.
The American Revolutionary War has begun.
In American Kingdoms, collaborative wiki writers create their own feudal lords and fiefs. Visit the Wiki

The first nations of the continent, who meet the newcomers as equals in war and in council. Proud and unbroken, they defend ancestral lands against every crown that would claim them.

The British crown and its loyalists, driven from the continent twenty years ago. The perfidious Redcloaks have not forgotten the New World, and scheme to bring the American Kings to heel once more.

Proud chivalric realms of the warm South, where courtly honour, the tournament and the bloodline rule as surely as any law. Fierce keepers of tradition and the old codes.

Norse-blooded settlers of the frozen north, raiders and seafarers whose claim to the New World runs deeper than any crown's. Bound to the sea, the saga and the old gods.

As settlers spread inland, free cities and trade republics took root far beyond the reach of both the Redcloaks and the Union. Ruled by councils of coin, they answer only to profit and their own hard-won liberty.

Along the western shores rises the Dragon Coast: colonies of Ming-descended settlers who crossed the great ocean generations ago, bringing the steel, silk and statecraft of the Middle Kingdom to a new frontier.

Roman mariners reached America around the year 0, founding distant colonies and leaving traces of their language, craft and law among the Native peoples. Their settlements vanished centuries ago; today, Rome’s American heirs survive only in disputed ruins, tribal memory and legend.

“From the Roman settlers to the Thirteen Kingdoms... discover the world's largest exhibition on the 1375 Revolutionary war, and the American Medieval Age! Manhattan Castle at Old Town, New York is proud to host a year-round exhibition exploring this defining chapter in American history.”
Originally developed in 1959 by renowned illustrator L.C. Meyenbecker and commissioned by the Royal Galleries of New York, the American Medieval Exhibition poster series has become synonymous with the era it depicts. Meyenbecker’s defining image - a knight of the Thirteen Kingdoms draped in the American banner, his squire presenting the sword to his outstretched hand - endures as one of the most powerful visual icons of medieval America.
In this medieval American world, who would you be? A Southern Gallant, a fierce Vinlandian viking, a shrewd councilman of a free Trade Republic, or perhaps a loyalist of the British Empire, plotting to overthrow the independent American Kings?
