This is how I see it:
1.-Similar geography, long narrow stretch of land
2.-The land was unified by a single government
3.-That government collapsed
4.-Because of its relative isolation, no outside power is able to take that land
5.-A myriad of different governments arised from the chaos. They are in near constant war with each other, leading to important improvements in military technology and administration
6.-Eventually there is a conscious and deliberate internal effort to unify the region under a single government. This effort is ultimately successful
Am I seeing things or are these valid comparisons about the patterns of history?
No
There are "valid comparisons about the patterns of history" for sure. This is not one of them.
