CivAtlas / About & methods

History through time and place.

CivAtlas is an interactive atlas and a reading library for exploring world history. Choose a period or region, locate a story, and compare what was happening elsewhere.

A selection, with visible gaps

The English Web edition currently contains 128 selected stories across six reading eras and seven regions, with historical coverage ending in 2024. It is an introduction for curious readers, rather than a complete national chronology, school syllabus or academic reference work.

The eras are navigation aids. Their boundaries do not imply that societies everywhere developed in the same sequence. A region with fewer entries is not less historically important; it has less coverage in this selection.

Dates should show their precision

Each story distinguishes a documented date, an approximate year, an ongoing process or a representative observation point. Long processes appear in overlapping eras and use their starting point on the timeline. A ruler's reign or an archaeological phase is not treated as one exact event date.

BCE and CE have no year zero. Where a source provides a month or day, the event order uses it; missing precision is not filled in as January 1. Dates and interpretations may differ between sources, so qualifications in the story matter.

Locations orient the reader

A map marker identifies a representative location for a story. It does not show every place involved. The colored range layer contains selected, dated snapshots with simplified geometry; it does not reconstruct borders year by year.

Core territory, cultural contact, military influence and tax relationships can describe different kinds of reach. Read the individual range notes before comparing them. Modern coastlines help with orientation, and unpainted areas must not be read as empty land. These teaching diagrams are not surveyed boundaries or statements of present-day territorial claims.

The base geography uses World Atlas / Natural Earth data. Mapping uses D3 and TopoJSON.

Illustrations set a scene

The era panoramas are AI-generated imagined scenes. They suggest aspects of everyday life and atmosphere, rather than documenting a particular event, building or artifact. They are not historical evidence or certified archaeological reconstructions.

Sources, review and corrections

Each story lists its bibliography as plain titles. The English edition maintains its own reference selection. References may support a date, an individual fact or a wider context; listing a source does not certify every interpretive sentence in an entry.

Content has undergone selected checks of dates, wording, source matching and representative locations. This is not an independent, sentence-by-sentence verification of the entire atlas. The detailed review record explains the checks, known limitations and regional coverage.

When comparing an entry with a source, distinguish the date of an event from a reign, construction period or later use. If you spot a discrepancy, keep the story title and the specific passage so the claim can be checked against its bibliography. You can report a correction using the feedback entry below.
