Prototype notice

This site is under development.

Across History is a prototype. Records, sources, features, and interpretations may change as we test the site and seek educator and historian review. Please treat it as an exploratory project, not a complete or independently reviewed educational resource.

Sources & method

The evidence is part of the story.

Every record links to its evidence. These summaries were assembled for a prototype and have not received independent historian review.

What Across History provides

Across History is an interactive, source-linked world-history explorer. It helps learners explore people, places, events, and documents across time and geography through curated records, timelines, a globe, and notes about evidence and perspective.

What the lines mean

Document trails, recorded responses, and diplomatic developments have different meanings. A shared date alone earns no connecting line. Arcs are visual links, not reconstructed travel routes.

How we rate sources

The provisional 1–5 rating describes source documentation: identifiable creator, traceable provenance, transparent method, and editorial context. It is not a truth, neutrality, or bias score. Potential interests and perspectives are described separately on each source.

Books and articles

Selected books and articles appear as further reading with their author, publisher or journal, date, scope, and perspective. We distinguish critical reviews from formal peer review. The first October 7 group includes Israeli, Palestinian, and Gaza-focused histories, plus a terrorism-studies article; their different scopes do not make this a complete bibliography or a balanced consensus. Reviews and peer review do not make a work neutral or settle disputed claims.

Whose history?

The Declaration’s equality language coexisted with enslavement and dehumanizing descriptions of Indigenous peoples. Letters, petitions, and later recollections expose different experiences; no single voice represents a whole community.

Contemporary sources and media

We name who produced a source, its purpose, and its known perspective and limits. Material published by a party to a conflict, including Hamas, is labeled as party-produced and is not treated as independent verification. Potentially distressing links show a specific text notice and ask before opening. Videos do not autoplay or appear embedded here.

Access and coverage

Availability at the publisher may change; Across History links to external source pages and does not host or license their material. The test cases are limited, and global coverage and native-language scholarship need substantial development.

Prototype status

Research text and interface translations have not received independent historian review or native-language editorial review. The current sample is open for testing and questions.

Source register and further reading

The register distinguishes primary evidence, institutional reports, documentaries, and secondary reading. Review or peer-review details appear when they can be verified. Publisher availability may change; no sponsored placements appear in this prototype.
