> EDITORIAL STANDARDS
History Brain turns complex subjects into short clues, answer facts, and readable articles. Compression is useful only when it stays accurate, contextual, and open to correction.
> SOURCE PRIORITY
Primary documents and official archives come first when available, followed by museums, universities, government institutions, and established reference publications.
> WRITING AND REVIEW
Questions and articles are written and maintained by Henry Montilla. New material is checked for chronology, answer ambiguity, internal consistency, and whether each clue fairly supports its answer.
> IMAGES AND LICENSES
Historical images are primarily drawn from Wikimedia Commons and other openly licensed or public-domain collections, subject to their respective licenses.
> DATES AND REVISIONS
Topic pages display their latest page-update date. Changes may include factual corrections, expanded context, clearer wording, or improved sourcing.
> CORRECTIONS
If something looks wrong or incomplete, send the topic title, disputed passage, and a reliable supporting source through the correction channel.
