How these maps are made
An atlas that argues about the past owes you its methods. This page is the honest version: what the maps are built from, where they simplify, and what we read.
THE BASE MAP
All cartography builds on Natural Earth (1:10m), a public-domain dataset, projected and simplified in our own pipeline. Coastlines, lakes and the country polygons you see are Natural Earth’s — nothing is traced from copyrighted atlases.
MODERN BORDERS, PERIOD NAMES — A STATED APPROXIMATION
The base polygons are modern country shapes, deliberately: they are accurate, consistent and legible, and readers know them. Period reality is painted over them — names, statuses, occupations and splits change with the timeline, and purpose-drawn overlay zones carry the borders that matter to the story (Vichy France, the Crusader states, the khanates, the shrinking Confederacy). Every atlas says so in its own legend: modern coastlines and borders are used as approximations. Where a modern shape would actively mislead — East Prussia inside modern Russia, for instance — the polygon is split so the period map reads correctly.
HOW OVERLAY BORDERS ARE VERIFIED
Overlay zones are checked, not copied. Reference datasets — CShapes 2.1, historical-basemaps, and the Pleiades gazetteer of ancient places — are used for verification only, because they contain errors of their own. The house rule: before any borrowed border is adopted, it must pass anchor tests — named places that must fall inside or outside it. Borders that fail verification are drawn by hand from the scholarship instead.
UNCERTAINTY IS NAMED
Casualty figures appear as ranges, because that is what the evidence supports. Debated turning points are presented as debated. Causes and effects are argued, not asserted — every chapter’s study layer says why historians think what they think, and where they disagree.
SITES OF MEMORY
Atrocities are marked on these maps as memorials, with sober copy. They are never quiz questions, never point-scoring, never gamified. That is a house rule without exceptions.
