History by the Numbers, Volume II brings together twelve visual infographics exploring rulers, warfare, exploration, science, technology, belief, and cultural exchange across world history. Through carefully selected groups, comparisons, and timelines, from ancient scripts and classical architecture to Crusader orders, ocean liners, vaccines, scientists, spices, and explorers, the collection makes complex historical subjects accessible through concise visual storytelling.

The numbers provide a framework rather than the whole story. Each infographic places people, objects, events, and ideas within their historical context, revealing connections across societies and periods while encouraging comparison, historical inquiry, and an understanding of continuity and change. Together, these visual histories offer students, educators, and curious readers multiple entry points into the diversity and interconnectedness of the human past.
