This personal site is an illustrative historical viewer, not an official atlas of borders or sovereignty.

Polygons come from third-party open datasets. Qing-era slices were adjusted so Tibet (and Taiwan while under Qing) are not shown as separate states — schematic only, not an official survey.

Nothing here is a claim for or against any territory, sovereignty, or international status. Not for scholarly, cadastral, legal, or diplomatic use.

Prefer authoritative sources for historical fact.
