Editing 2nd millennium BC (section)

==== Unrest of the 16th century ====
About a century before the middle of the millennium, bands of [[Proto-Indo-Europeans|Indo-European]] invaders came from the [[Central Asia]]n plains and swept through [[Western Asia]] and [[Northeast Africa]]. They were riding fast two-wheeled [[chariot]]s powered by [[horse]]s, a system of weaponry developed earlier in the context of plains warfare. This tool of war was unknown among the classical civilizations. Egypt and Babylonia's foot soldiers were unable to defend against the invaders: in [[1630 BC]], the [[Hyksos]] swept into the [[Nile Delta]], and in [[1595 BC]], the [[Hittites]] swept into [[Mesopotamia]].
