Travel time is more important in wartime. It's quite hard to conquer a place if your supply lines are too long. But if you do conquer, you can hold it for a long time with much less effort. I found this part of the article to be nonsense: Alexander the Great conquered most of the “known world” of his day. But his conquests took them 10 years, and after his death, the empire was split in six. Which further proves that a strong army, without proper transportation technologies, can’t hold an empire together. Uhhh..... first of all dude, only taking 10 years to conquer the entire known world (when the conqueror is 20 years old) is pretty fucking insane, let's give the kid some credit. But yeah, his empire was split in six when he died. Why? He had no heir, he was the king of the entire known world, and he died suddenly. Conflict was bound to happen. This in no way provides any evidence to this point that transportation is critical to keeping an empire.
