Starting information:

I was playing Europa Universalis IV and found an "Extended timeline" that lets you start close to year 0 instead of 1444. The extended timeline is a user-created mod and is independent from the creators of EU IV. I was wondering how accurate this timeline is. I know some of the added things are not 100% accurate or real, but not sure how good it is as a map for overview. Can I trust this as a quick overview of borders from around year 0 to present?

It is possible to only go a year forward, but that would take too much time, so I took 10.
