Hi HN! I’m Klokan, one of the creators of TimeMap. It’s exciting to see this project here — thank you for the interest and support!

We just launched TimeMap on Product Hunt: https://www.producthunt.com/posts/timemap If you find what we’re building valuable, an UPVOTE there would mean a lot.

Stanford University recently hosted an event to introduce TimeMap to the world, which you can check out here:

* Recording on YouTube: https://www.youtube.com/watch?v=VZspMtwYI98

* Event page: https://events.stanford.edu/event/the-future-of-history-disc...

The talk dives into how TimeMap was built, including our use of Linked Data, OpenHistoricalMaps, LLM pre-processing, indexing algorithms, and more. It also highlights amazing partner projects like Pelagios, TimeMachine, and our amazing partner institutions such as the David Rumsey Map Collection, British Library, ETH Zurich and many others.

TimeMap has been a dream project of mine for years — I’m thrilled to see it coming to life and would love to hear your thoughts or feedback!

For context: I’m also the founder of OpenMapTiles.org, a MapLibre.org board member, author of GDAL2Tiles, and contributor to other open-source projects. Currently, I’m serving as the CEO of MapTiler.com.

Looking forward to the discussion, and thank you for taking the time to check this out!

Nice! Small nitpick, as a Dutchie: we changed the shape of our country quite a bit over time by reclaiming sea. The map of the area now occupied by The Netherlands was very different two thousand years ago from what your site shows.

(And this had geopolitical consequences, e.g., the invading Spanish could not cross some of the bodies of water present in the sixteen hundreds that are not there now.)

[wongarsu]

The German coast also had notable man-made changes, though far less extreme than what the Dutch did

This has been a dream project of mine too, so happy to see that it exists.

One thing that I've also wanted was to be able to reason about the total timeline using the Holocene calendar[1] instead of the standard BC/BCE AD/CE timeline. It makes it easier to internalize how long ago (or how recent) certain civilizations were without having to do the wrap-around math in one's head. Would be nice to be able to maybe toggle that view.

[zamadatix]

Or, perhaps a bit more intuitively, an option to show the timeline as "years ago".

Thank you Kiokan, I've been looking for something like this since High School.

They way history is taught misses a lot of the context that only makes sense when you put it into a map like this one.

If you could somehow "open source" at least the data side of this, I'd be glad to contribute. I have a bunch of history books from ancient latino civilizations.

You may be interested in OpenHistoricalMap: https://www.openhistoricalmap.org, which anyone can contribute to (you can read much more about it here: https://wiki.openstreetmap.org/wiki/OpenHistoricalMap). Edit: I didn't realize at first but from other comments it sounds like TimeMap actually pulls data directly from OHM.

The is such a great project. I am a little confused by the oldmapsonline.org/timemap.org thing. Are they different names for the same thing? Why is the title timemap.org, when the URL is different?

Hi Klokan,

This is a really project and really helpful to understand history. I noticed that several data points about the Portuguese Colonial Empire are wrong, is there any place where I can submit a ticket about it?

When the royal succession crisis took place in 1580, according to the blood line, the King of Spain was indeed the next in line but both Kingdoms remain independent, you can also find evidence of this in the name: King Philip III was called King Philip I in Portugal, the following one (Philip IV) was named the Philip II. In Timemap, when you check 1580, it shows the Portuguese territories with the Spanish royal flag, which is wrong because everyone understood back then that if Spain tried to dictated anything about the Portuguese overseas territories, this would be taken as a declaration of war. This is reason why the Treaty of Tordesillas was signed, Portugal and Spain divide the world and would not step on each other.

Also found things like Malacca, the flag is missing the dates of duration: 1511-1641 Same for Macau, the map states that the Portuguese rule ended in 1845 but in reality it only became independent in 1999. Many other important missing bits that, although technically they don't as territories, do represent groups, example: The city of Nagasaki was built/shaped by Portuguese merchants during 1511-1641 and was indeed under Portuguese administration during 1580-1586.

Among many other bits that would make this reply too long for HN.

Hi! It's done beautifully but there are some... inconsistencies.

Is there a process to provide feedback and correct errors on the map?

[klokan]

Yes! Please just use the "Feedback" button on the side of the interface - after you zoom the map and select time - then you can annotate, and it gives us most relevant context to your feedback

[grahamj]

Yes I'd like to report the error of Taiwan being labeled "Republic of China"

[singularity2001]

"inconsistencies" that's a friendly way to put it. The data is severely lacking for the world before the bronze age collapse. Upside: it can only get better over time.

[ninalanyon]

Interesting. It seems a bit slow but perhaps that's my laptop.

Why are the boundaries of Denmark, Norway, and Sweden not shown for the Kalmar Union? They are for England at Scotland in 1620 when they were under the personal union of James, (VI of Scotland I of England). What's the reason for the difference?

[dotancohen]

Also the Ottoman Sanjaks are not distinguished. Perhaps only top-level boundaries are shown.

[shireboy]

Really amazing site. I could spend hours on it. Only real suggestion: I’d like to see more stuff. Layers for notable events in different categories besides just battles. It would need some curation but user- submitted content. Or maybe use ai to find various time/place on Wikipedia and decide if it is “notable”.

Ux is great but I got in a state in maps where I couldn’t get back the control at the top that lets you pick people/battles without refreshing the page.

[phasnox]

Thank you for this awesome project.

Question, why Ferdinand III does not appear under people during 1200s on the Hispanic area?

He is arguably the most important historical figure during that time period:

- Unified Castille and Leon

- Lead the reconquest that resulted in what is Spain today.

https://en.wikipedia.org/wiki/Ferdinand_III_of_Castile

EDIT:

He was the literally the directly responsible of the map changes during that era

[abe94]

This is something I've wanted to see for years - thanks so much for building this - is there a way to suggest edits? Perhaps a way to link a wikipedia account in order to create an article?

It would also be cool to have filters of pre history, Hunter Gatherer, Early Farming, Bronze age and so on!

This is awesome! I've been thinking about making something like this, but felt like a huge undertaking. One of the major reasons I wanted it was to visualize how (ie under which treaty) were boundary lines moved or redrawn.

[dotancohen]

Be careful assuming that the dates are correct and that the borders are drawn exactly where they should be. This map is a great guide, but don't base decisions on it.

Also many historical treaties did not define borders to the level of detail they we are used to today.

[BehindBlueEyes]

I was so excited to see this project as I was dreaming of such a thing, followed by immediate disappointment that west coast indigenous territories aren't included. Curious how what appears on the map or not is decided, is it just repackaging existing data sources? Are those sources editable by anyone (like OSM)?

Either way, good job! As a low key OSM contributor, this motivates me to contribute to the mapping, if data can be added by the public.

[Fauntleroy]

This is a well implemented and remarkably responsive version of what I've always wanted--a map that travels throughout all of human history. I'm so happy to see this today, honestly.
