4P Research — A history of humanity
A source-led human-history timeline across regions and eras, distinguishing historical claims, source records, recorded beliefs, and evidence boundaries.
A source-led history of humanity
This 4P Research timeline follows human history across regions and eras through archaeology, material records, written accounts, and institutional sources.
Each entry separates the historical claim from the source record and states the evidence boundary. Approximate dates, disputed chronologies, and recorded beliefs remain explicit; this is a reviewed starting chronology, not an exhaustive account.
4P Engine operating context
