In the times prior to the creation of the national borders, how were people viewed as they moved from one region to another. Did people have to have established documents, or were most people living without documentation?
Hi OP. As currently worded, this question could be interpreted to be asking about almost every culture that ever existed... which would break this sub's "no example-seeking" rule. Could you let us know what country/region/culture and time period you're asking about? That information would greatly assist anyone considering answering here. Thanks!
