A tribe or a nation (say tribe A) leaves their land for whatever reason (poor soil, threatening neighbours). Another tribe or nation (possibly with the members of the original tribe who were left behind) develops a settlement on this land (say tribe B). Possibly this new tribe overcomes the problem that originally pushed tribe A out of the land. The original tribe comes back to reclaim their land. What is the most recent example of this? Reconquista makes sense however I'm looking for more of a peaceful initial "exodus" rather than invasion. Also with Reconquista it's hard to say that the tribe/nation that reclaimed the land was the same that left it (as far as I understand).
Updated: The correct answer would indeed be "yes". Rephrased the question so it's not a laundry list one.
