well, since the dawn of time, humans created a concept of owning territory, as a way of showing superiority to others, it's an instinct most animals have, but human beings have used it as a method, with our more developed intellect, of controlling land in order to make it prosperous, and to benefit the group as a whole. typically the strongest would be the leader of the pack, and their genes are naturally strong, so all their children must be too, hence the birth of the despotic monarchy. sometimes a land (for instance the roman empire) would be too large to govern, and so the leader would have lords control land as "mini-kings" to control that land and make it prosper (hence the birth of feudal monarchies). years and years later, after many power struggles to take land and create a prospering kingdom, new systems are introduced to allow the people more of a say, since the mentality of man has now changed, and morality comes before necessity, hence the birth of Republics. years and years after this occurs, modern day society, interconnected by technology not even thought of 100 years ago, creates a revolution of democratisation around the world, allowing for people to share opinions, talk, learn, love and enjoy each others company, due to freedom movements and the allowance of leaniant and fair governmental systems, the once fought over territory is now a political line to allow for a chance of co-operation. Countries only came into existence because of territorial goals, animals marking out where they roam, but now, it's something more, political alliances, co-operation, and all other manners of our creation have helped to make our society better, i know you didn't ask for a history lesson, but this should help you understand that borders are just lines drawn to help us work together, without disputing territory (borders are now disappearing due to world co-operation), things will change, with time.1
