Timeline Compare is a free web app for reading history comparatively. Pick two topics — say, US history and Korean history — and it draws their timelines side by side on one shared time axis, so events from the same years line up with each other.
- What is Timeline Compare?
- A free web app that places two historical timelines side by side on one shared time axis, so you can read them against each other — US history next to Korean history, for example.
- How do I compare two timelines?
- Search a topic and add it as a track, then search a second topic and add that too. Each track gets its own column on the same time axis.
- Which topics can I compare?
- Curated headline topics — US, Korean, Roman, Chinese, British, Ottoman, French, and German history, plus the history of science — load instantly. Any other topic is researched on demand from Wikidata and Wikipedia.
- Is Timeline Compare free?
- Yes — free to use, no account needed.
- Where does the data come from?
- Curated seed timelines, plus Wikidata and Wikipedia for topics researched on demand. Every event on the board links back to its sources.
- Can I share a comparison?
- Yes. Every comparison has its own link, such as ?topics=us-history,korean-history, that opens the exact same board.
