The CENTENNIA Historical Atlas

A dynamic, animated guide to a thousand years of history...

The Centennia Atlas is a map-based guide to the history of Europe and the Middle East from the beginning of the 11th century through the early 21st century. It is a dynamic, animated historical atlas including over 9,000 border changes. The map controls evolve the map forward or backward in time bringing the static map to life. Our maps display every major war and territorial conflict displaying the status of each region at intervals of a tenth of a year. The maps reflect actual "power on the ground" rather than internationally-sanctioned or "recognized" borders.

The video above is a capture from the Centennia Historical Atlas: Nations Edition. It's a sample of the animation. Since many videos have appeared online using our animations (usually unlicensed!), we have to emphasize that the Centennia Historical Atlas is not a video. It's a desktop app, a software atlas, that can be zoomed in and out, played forward and backward in time, linked to a database of events and explanatory text. Centennia is a guide to history, and it's a convenient way of putting modern events in historical context.

From Kevin Kelly's review of Centennia, published in the Whole Earth Catalog:

"As a kid I dreamed of maps that would move; I got what I wanted in Centennia. This colorful political map of Europe and the Mid-East redraws itself at yearly intervals from the year 1000 to present. It's a living map, an atlas with the dimension of time. I can zoom around history, pause at particular dates, or simply watch how nations melt away, or disintegrate into tiny fragements, or unite! Year by year the outlines of tribes and nations spread, retreat, and reform almost as if they were tides or infections. The resolution of detail (almost at the "county" level) is astounding; the breadth of time (ten centuries) thrilling. It rewards hours and hours of study."

Kevin Kelly is editor-at-large and co-founder of WIRED magazine and one of the board members of the Long Now Foundation, devoted to thinking on a millennial timescale.

The Centennia Historical Atlas was required reading for all beginning students at the US Naval Academy at Annapolis for over fifteen years. Over 1150 copies were purchased annually for all prospective naval officers at Annapolis. The software serves as a visual introduction to Western History from a cartographic perspective. Centennia is also licensed by hundreds of secondary schools, colleges, and universities worldwide.

Current editions of the Centennia Atlas include text in Greek and German, as well as English. To change language while running Centennia, on your keyboard, hit "D" for German (Deutsche), "L" for Greek (ELLenika), or "E" for English.

Individual home users also purchase the Centennia Historical Atlas. It's ideal for anyone who loves maps and history, and it's also popular among genealogy enthusiasts. There's no easier way to get a long-time-scale perspective on the history of the regions of Europe and the Middle East than by watching the borders shift back and forth in Centennia.

Professor Charles Ingrao, Purdue University wrote:

"The Centennia Atlas offers an instant antidote to the problem of changing frontiers. It permits you to view any part of Europe, North Africa or the Levant from A.D. 1000 to [the present]. You can also go forward (or backward) in time, which permits you to see the map change in five-week intervals for the period and region of your choice. Centennia also provides a "historical gazette" and glossary of names/places that students might find useful. It even traces the changing battlefronts between countries in wartime, so you can follow the inexorable march and retreat of the Austrian armies in the Balkans and elsewhere. I was most impressed by the developer's incredible eye for detail, which was more precise (and often more accurate) than Magocsi's new Historical Atlas of East Central Europe. Centennia is no less precise for Germany..."

The Centennia Historical Atlas software runs under Apple MacOS (Monterey, Big Sur, Catalina, etc.), as well as Microsoft Windows (11, 10, etc.). The app has no significant system requirements and will run well on almost any computer manufactured in the past ten years.

The latest version of the atlas, Centennia Historical Atlas: Nations Edition, is available at no charge. It's free. Centennia Nations Edition covers the 150-year period from 1789 to 1939, from the beginning of the French Revolution through the Napoleonic Wars, the revolutions of the mid-19th century, the unifications that led to the creation of the modern nation-states of Germany and Italy, the wars of liberation in the Balkans in the early 20th century, the First World War, the dissolution of the Ottoman Empire, the creation of the modern map of the post-colonial Near East, the Spanish Civil War in the 1930s, the rise of Nazi Germany, and the events leading to the Second World War. All of the data, maps, and text for the complete edition of the Centennia Historical Atlas covering the ten-century period from the year 1000AD to the present are included in the app and can be accessed by entering a license code (available for purchase).

What a stunning piece of both pleasure AND education for all of us, i.e. for Daddy and for my kids 11 and 13. Unfortunately most people don't yet know this marvellous piece of edutainment. I hope this will change quickly.

I have been using this program since 1999! I'd LOVE to see an iPad version as I teach 1:1 and have access to airplay. Thanks for keeping this program alive and available after all these years!

How do I download the free version of Centennia Nations Edition? I do not see a link on the website. Thank you!
Frank Reed wrote: 2/8/2023
Sorry for the confusion, Cynthia! Any of the download links here will get you the free version, Centennia Nations Edition. Then later if you buy and enter an access code that will convert into the complete edition of the Centennia Historical Atlas. So there's just the one download ...

I have been using this teaching my Modern European History class with great success. It always draws a little crowd when the map is left in free animation on a big screen!

At last! I'm looking forward to using CENTENNIA Research Edition when my department completes the purchase ..... assuming we can fund it. Can you tell me: are the KML files compatible with Google Earth? Would I be able to show the historical borders of Europe, e.g., in 1499 displayed with the perspective and view features in Google Earth?
Frank Reed wrote: 12/8/2022
Hello Ellen. I have added some sample views showing Centennia KML files viewed in Google Earth.

Hello, Clockwork Mapping. I use the MacOS version of your Cantennia Atlas, and I wonder if you plan to port it to iPad. I think it would be really *slick* on a tablet! Also, do you intend to expand it into the tenth century? My specialty is medieval France, and I would like to see more detail there. Just a wishlist! Thank you for this amazing atlas.
Frank Reed wrote: 8/14/2022
Yes, indeed. We are working on an iPad version. It's mostly a matter of funding. The new "Research Edition" of Centennia will, we hope, provide enough revenue to get the iOS version launched. As for the other item on your wishlist --more in medieval Europe-- it's certainly a possibility in the next year if we can get enough interest. Thanks for letting us know what interests you!

Your historical atlas shows details that I have never encountered anywhere else. I first discovered your maps through a viral video on youtube, and I was appalled to learn later that the video was published without attribution and violating your copyright. I hope you at least got some visitors to your site out of that. It's an astounding accomplishment and obviously a huge amount of research and artistry went into its creation.

Can you email me and let me know if you have any deals for students? I would love to be able to assign this to my students in my European History survey class this summer. Thanks, Phillip Perry, Ottawa.
Frank Reed wrote: 6/22/2021
Hi, Phil. Absolutely -- we do have discount pricing arrangements for students in classes, assuming you would be ordering ten licenses or more. We also have licenses for history departments and small computer labs/libraries. I'll email you.

I can't tell you how much I LOVE this atlas. I've been using it for five years in my genealogy research, and there's nothing that compares. If I need to know what was happening in Baden in 1660 or Brittany or Danzig/Gdansk in 1925 or Milan in 1805 or anywhere else at any date... then I can turn to the "Centennia Historical Atlas" for insight. I only wish it covered more centuries, and I'm really looking forward to the version covering the history of North America. Thank you!

Hello, my son purchased one of your maps without me consent and used my card. Is there anyway to get a refund for this purchase?

If I want to use a paper check to pay for Centennia, can I use a discount code with it?
Howard Mayhew wrote: 3/12/2021
Does this atlas has a search for a city? As a Family Researcher, I get names like "Bohemia" or "Pershia"(sp) and the intergal mapping program in Legacy does not report finding these countries.
Will buy latest version for use if it does this search.

Wow! I found this through a Youtube video (with attribution!) after searching for something similar (a detailed map of the Holy Roman Empire) and this does not disapoint! While I'm a little shocked at the price tag, even the free version is leaps and bounds ahead of your nearest competitor (Harvard University, who doesn't let non-students access the map for any price AND whos map isnt even as detailed!) I know I will eventually buy the full version as I love this so much already!

Another voice of acclaim for your work. I licensed the application with great delight soon after 2005.

Please add my vote to the requests for an iPad version.

With appreciation and thanks,

I see little mention of genealogy. Without Centennia (Millennia back in the 1990's) I don't know if I would have ever known to look for my northern Germany ancestors in the Scandinavian (Denmark) section of the genealogy library. My grandmother was born in Lublin. I assumed Poland, not Russia at the time. A very useful genealogy tool, thanks.

This is cool, I did not realize how much Europe change in that time period.

I use this atlas for about 10 years with great pleasure. It is practical, precise and very useful so I recommend it also to my students of history, culturology and hungarology. Thank you very much!

I have used Centennia in my classes in the past. I still have the software on my computer but it won't open, it says the developer of the app needs to update it for it to work with current version of MacOS. What do you suggest? Do I need to re-purchase the app?
