This was hard to watch. It must have been much harder to make and submit though.

Ignore Paradoxed258, he obviously doesn't know scientific terms. This flash was a good try, as others have said, i'd suggest putting more time and effort into making you presentation one unilateral theme. As well you should have logged it under the "Informational" category ;)

As the previous reviewer said, this is an intriguing idea that I'd like to see accomplished, but you went about it in a relatively horrendous way. The maps used were of differing origin, were of low quality and were confusing to interpret.

If you were to do a significant amount of work on this by creating your own maps (utilizing your own research, of course) then this would be a great video. Kudos for the historical/geographical intrigue, though.

..badly executed. The maps are of bad quality.
You introduce the movies with a promise of a presentation showing the evolution of realms and countries. This is really something I would like to take a look at. But while the dates the maps represent increase you switch between different color codings, legends and scopes of view leaving the watcher confused und messing up the initial intention of presenting an evolution.
The historical maps are interesting but I'd rather have a consistent code of information.
Maybe you could add a panel to choose between playing the evolution and taking steps in time forward and backwards.
