European expansion, New World Order
Warfare had undergone many revolutionary changes over the centuries. Hittite chariots, for example, are said to have spread east and south bolstering aristocracies at the dawn of urbanization some three thousand years ago. Then, the quality of swords and armouries infinitely improved, as the infantry steadily took centre stage, and the Iron Age swept across Eurasia and, later on, Africa. The Chinese invented the crossbow as early as the 7th Century BCE, and Hannibal surprised the Romans with elephants few centuries later.
