Stages Purple and Blue

[Lews Therin]

Hey, just wondering, how does pSpiral Dynamics explain tribes that extend far beyond the Dunbar Number? It is my understanding that purple share an identity with those whom they share a personal connection with, and blue extends that to include cultural connections.

But how does that explain tribes that occupy many villages through a large area, like we have some today in the America's and Africa, but also like the Gauls, Goths and Iberians in ancient times?
