What was happening everywhere else?
Most history is taught one country at a time. Drag through five thousand years and read a single moment across ten world regions at once — each event with its sources.

Read history sideways
A textbook moves through one place at a time: first Rome, then China, then the Americas. You finish knowing each thread, and still cannot say what the others were doing on the same afternoon.
This is a synchronological chart — ten parallel bands, one per world region, time running left to right. Put the cursor on a year and every band answers at once.
Start from a year
Pick a moment and see the whole world at it, not just the part your textbook covered.
Every fact carries its source
Each event lists where it comes from — Wikidata, the language Wikipedias, and for World Heritage sites the UNESCO listing itself. You can check any claim without leaving the page.
Dates that are only known to a century are shown as a century, not a false exact year. Where a location is schematic rather than a precise site, the map says so.
