A chronological view of world history, on a map, in motion. We're visual people — we need to see events and relationships laid out in space and time to really grasp the complexity, the nuance, and the astonishing connections between people across the ages. Modern mapping tools finally make it possible to give history this dynamic, geographic form: not a timeline of dates, but a living map you can watch evolve.

The goal is always the big picture first — how empires rose and fell, how borders shifted, how one civilization's edge touched another's — with the detail available underneath for anyone who wants to zoom in.

Please note that the information presented in this system should not be treated as accurate or authoritative. Do not use it to make any decision. It has not been reviewed by historians or subject-matter experts — it exists to give a general impression, a starting shape of history you can explore visually, not a reference.

We work top-down: start with the big periods and regions, get the broad shape right, then progressively fill in detail. At every step we capture the sources behind the information, and where possible we cross-reference multiple recognized sources rather than relying on a single one. This takes time, and we're patient about it — breadth first, depth as we go.

Where we start

Today, the majority of the content in this system is consolidated from public sources like Wikipedia. It's a remarkable starting point — broad coverage, constantly updated, freely available — but it comes with real limitations: inconsistent sourcing, varying levels of scholarly rigor, and gaps or simplifications depending on the topic. Every piece of information carries a visible reference back to where it came from, so nothing here is presented as unattributed fact.

Where we're going

The long-term ambition is to move beyond secondary/crowd-sourced references and connect this map to institutions that hold the actual primary evidence — original manuscripts, historical maps, treaties, coins, artifacts. The BnF (Bibliothèque nationale de France) is a good example of the kind of collection we'd eventually like to link to: a place where a claim on the map could point not just to a Wikipedia paragraph, but to the digitized original document or object it's based on. That's a future phase, not where we are now — but it's the direction the sourcing model is built to grow into.

Historical Accuracy

Most content is consolidated from public sources such as Wikipedia, with references marked directly in the tool. We rely on the accuracy of those sources when reproducing maps, and manual errors may also be introduced during capture.

Geographical Accuracy

Based on available historical information and maps. Some source maps have very low precision — enough to convey a general area, but boundaries and frontiers are sometimes captured at a level where errors of hundreds of kilometers are possible.

Period Accuracy

Source maps are typically designed or valid for one specific year. When we represent a period with a START and END date, we approximate that the map holds for the whole period — which means changes within that window aren't yet reflected. Splitting periods and duplicating/refining maps for sub-periods is an ongoing iterative process.
