I typed Castille over and over, and it didnt accept it because of the two l's. I reckon this is a fairly common and legitimate mistake and warrants a type-in.
Done, although I don't really see the necessity, since basically 100% of people will type in "France" and thus get all countries where "Gaul" would be applicable.
The commonly agreed date for Andorra's independence is 1278 (see https://en.wikipedia.org/wiki/History_of_Andorra), so it should also appear in the 1400 map.
Cool quiz. I think Gallia Transalpina/Transalpine Gaul (as well as Gallia Narbonensis, since currently it's only "narbo") should be accepted for Narbonensis. I actually tried that several times as the name was stuck in my head from reading Colleen McCullough's books about Roman history. I also thought of Gallia Cisalpina but it seems that it wasn't officially a province anymore by 100 AD.
The dates refer to the establishment of a country and it's decease, not to the last time the territory changed in Iberia. For France I chose 1958, because that was when the current constitution entered into force.
It says "(Provinces of the Roman Empire)" above the list of provinces. 100 would be a boring year, if the only country on the map were the Roman Empire.
I don't like how you included the provinces for the 100 and 418 map. I just didn't think of that since it is nowhere mentioned. Maybe add some information regarding that or accept rome.
There is a map, which in the case of 100 obviously doesn't just show the Roman Empire, above the list of provinces it says "(Provinces of the Roman Empire)", and East and West Rome were separate countries, each with its own leader.
100
418
750
1000
1400:
Crown of Aragon
Crown of Castile
Duchy of Gascony, Emirate of Granada and Kingdom of Navarre
I thought it was referring to the moment when the territory got the shape shown on the map.
But actually, that would have meant at least 2 countries had the same dates: the one which gained possessions and the one which lost them
