This is very easy to see on Germany. Despite having same language, history and racial attributes, they didn't feel equal between Northern and Southern Germans.
Northern Germans would assimilate more with Sweden than Southern Germans. Also Southern Germans assimilated with Italians, Ungars, Romanian or Slovaks instead of Northern Germans.
