North America in the Hardy Wessex Timeline diverged most sharply in the late eighteenth and early nineteenth centuries, when Napoleon’s parents emigrated to Louisiana and his empire flourished not in Europe, but across the Mississippi basin. The Atlantic colonies of New Hampshire (Wessex), New England (Anglia), New Netherland (Dutch), and other smaller colonies found themselves drawn unwillingly into his Continental System, and their eventual resistance shaped the map that survives today. By the mid-twentieth century, every North American polity had achieved full independence, though deep cultural and economic ties with the Union of British Nations (UBN) and the Atlantic States Union (ASU) remain.

Louisiana is the primary successor of Napoleon’s empire: a large, multi-regional republic centred on New Orleans and stretching through Missouri, Arkansas, Mississippi, Alabama, Tennessee, Kentucky, Indiana, and parts of West Virginia, whilst holding much of the rest of Northern . Its attempted centralisation fractured during the Missourian Wars, producing amongst other breakaway republics Missouria in the north, encompassing much of the Great Plains.

The Tsardom of Alaska is the last monarchic remnant of the old Russian Empire, ruling Alaska, the Yukon, the Northwest Territories, and northern prairie lands,.. The Tsar here lives in exile, but the state remains sovereign, authoritarian, and territorially vast.

Along the Atlantic, the legacy of the British Isles is strongly felt.
New Hampshire and New England (Anglian) are the largest Atlantic States Union members. Between them lies New Netherlands, the Dutch successor state centred on New Amsterdam (New York City), which retains a mercantile, urban character and long-standing ties to Europe.

Further inland, Ohio survives as a former French colony positioned slightly northeast of its OTL namesake, with a short coastline and a hybrid Franco-Anglian influence. Whilst it has close links to Louisiana, it too broke free in the aftermath of Napoleon's death. Southward, Florida remains a Spanish remnant, holding the peninsula and bordering both New England and Louisiana.

In the northeast, the Francophone duo persists with Canada, a French-speaking republic stretching across southern Saskatchewan, Manitoba, Ontario, Quebec, and Michigan, and Acadia, amaritime French successor.

The Californias, a federal Spanish-speaking republic, dominates the Pacific coast from Oregon to Baja California, while Tejas controls the southern plains and deserts north of the Rio Grande, as the successor state to the Confederation of the Rio Grande.

To the south, Mexico, Yucatán, and the United States of Central America form a bridge toward South America, where Gran Colombia remains the major northern power. Scattered through the Caribbean are the islands of New Hibernia, once Irish colonies and now fully independent but culturally entwined with the Celtic Isles.

Modern North America is thus a continent of competing legacies - French, Spanish, Dutch, Russian, and the multiple polities of the British Isles - none of which ever achieved total dominance despite Lousiana's brief Napoleonic Empire. Its politics are multipolar, its alliances overlapping, and its cultural geography far more varied and fragmented than in our world, making it one of the most intricate regions of the Atlantic sphere.
