Thank you for your help in the improvement of the map. The map currently shows the countries already in the database. The slider allows you to see the final result.

Countries are created from concatenated borders. Borders are only points lists. Countries are also described by their (beginning and ending) dates. Use the buttons to add or edit existing borders or countries.

Note that this page is under development, some features could not function properly. I am well aware of the fact that cartography can be tricky and raises lots of questions (map projection, borders or countries international recognition, color choices, ...) but I wanted to give it a try, not being fully satisfied with Gifs.

Any remark, suggestion, criticism or question is welcomed: use this form.
