Garlean timeline question

[Alleo]

The question remains: How long does a country have the rights to a place? We know that they had been away from their original country for centuries (Varis himself even said that). Centuries means quite a few generations that have passed. Maybe those that originally defeated them dont even live there anymore. Does this give Garlemald any right to take it back? In their view it does but again when does this stop?

Seemingly some anchestors of the Garlean race are from Goug..which was destroyed and they had to flee so it was seemingly not the same place that they were forced to leave because of other people. So was their old place in Ilsabard really theirs or did they also take it by force? (And lets not forget that even them banding together as tribes to fight back against the onces that forced them out was not always done peacefully. Some of those tribes were forced into that alliance against their will which is stated in the lorebook too. So how many of those that are even living on Ilsabard do want to be under their rule?)

Also like Kusanagi points out, if its reasonable that Garleans should take back their land after centuries...then they really should not go around and conquer other countries or be angry when those people fight back against them.

In the end I wonder if this was not just another plan by the Ascians. I really doubt right now that all their progress with Magitek was completely on their own and maybe they played a hand in forcing them out too.

Aulus, Varis, the lorebooks, and the Garlean partisans in the fandom have pointed to the inability of pureblooded Garleans to manipulate aether as the causus belli for Imperial aggression: the Garleans are just defending themselves or getting revenge for being forced into the inhospitable northern reaches of Ilsaberd by the magically-inclined races. The implication seems to be that happened recently. Do we know where the Garleans were originally, when they were forced north, and who drove them out of the more habitable areas?

Well they were forced out from a part of Ilsabard to another part of Ilsabard. Eorzea and Doma had nothing to do with any of that. So Garlemald is purely the aggressor on this (and we know that the primal summoing as reasons are also just lies) so if they somehow think they are right with taking this out on the rest of the world then that would be messed up. And as Varis himself and the lore book pointed out, they had centuries after they are forced out before they were a united state. And after that it still took some years to make it an empire. So no its not really recent which makes the argument that it was in their right even worse.
