What we don't know - their calendar system.

What we do know - there are millenia of history lost to the ages. Also, the Great War finished 80 years ago, it lasted about 10 years, and there were 100 years of tension leading up to it, for a total of 190 years.

So depending on when their calendar system starts, they're at least at the tail end of the second century. Or the end of the first century, in the case that they started counting from the Great War.
