Family research · Hub · Phase 6 of the world atlas
Belgium, the Netherlands, and Luxembourg started as one Burgundian bloc in the 1400s, split violently over religion and rebellion in the 1580s, and have been pulled back together and pried apart at least three more times since — by treaty, by conquest, and by a quirk of royal succession law. Below is one map that traces all of it, six centuries in one slider.
Country pages for Belgium, the Netherlands, and Luxembourg are coming in a later pass — for now, drag the map's slider to see the region's whole story at a glance.
A real, traced map — actual coastlines and borders from GeoJSON boundary data, not schematic shapes. Luxembourg is genuinely tiny next to its neighbors, so its shape here is drawn about 35% larger than true relative scale, just enough to stay legible without losing its real outline. Drag the slider or press play; each snapshot simplifies a messier reality into the dominant power of the moment.
Real traced borders (simplified from GeoJSON boundary data, current-day coastlines). France and Germany are shown faint for context only, projected through the same coordinate transform as Belgium, the Netherlands, and Luxembourg, but not tracked era by era. Luxembourg's shape is shown at its modern, post-1839 borders throughout, for consistency — the 1839 partition that shrank it is explained in the story text rather than redrawn geometry.
Maps are bad at showing when; timelines are bad at showing where. This uses real transition years instead of the eleven arbitrary snapshots above — one horizontal band per country, colored the same way as the map, so you can trace exactly how long each era actually lasted (watch Luxembourg's extra 75 years tied to the Dutch crown after Belgium leaves in 1830).
Every country keeps its true color, but anything unchanged from the previous frame fades to low opacity; only the country or countries that actually changed hands stay bold with a solid outline. A caption under each frame spells out exactly what flipped. No slider to operate — scan left to right, top to bottom, and watch the map redraw itself like a flipbook.
This started as a family history project: tracing the flags that flew over the lands our ancestors came from, close enough to paint accurately — correct colors, correct proportions, correct dates. The Low Countries earned their own hub because their story is the opposite of most of the atlas so far: instead of one region fragmenting permanently, this is one bloc that keeps getting pulled apart and pushed back together, by war, by treaty, and once by nothing more than a difference in royal succession law.
Colors are close historical approximations; pre-19th-century swatches especially are informed reconstructions, not official specifications, and are labeled as such throughout. The regional map above simplifies five and a half centuries of messy, overlapping, disputed control into eleven snapshots — useful for orientation, not a substitute for the detail each country's own page will carry.
