When looking at a political map of the world, one might wonder why some countries are so funny looking. There are long and thin countries, countries with weird protrusions and depressions, even countries inside other countries. Due to the seeming difficulty with which borders are created and changed, it would seem that these arbitrary demarcations are either poorly made, intricately planned, or completely random. In reality, country borders are made through a combination of all three.
The interesting video above, made by Geography Now, explains the means by which most borders are made. Whether through geographical necessity, strategic maneuvering, or simply convenience, leaders throughout history have managed to create some very odd borders, and Geography Now explains the main ways they come about in an entertaining way with the help of amazing and helpful animation.
