Book excerpt: This book contends that Indo-European languages came to Greece, central Europe, southern Scandinavia and northern Italy no earlier than ca. 1600 BC, brought by the first military men whom Europeans had seen. That the Greek, Keltic, Italic and Germanic sub-groups of Indo-European originated in the middle of the second millennium BC is a controversial idea. Most Indo-Europeanists date the origin a thousand years earlier, and some archaeologists would place it before 5000 BC, as agriculture spread through Europe. Here Robert Drews argues that the Indo-European languages came into Europe via military conquests, and that militarism – a man’s pride in his weapons and in his status as a warrior - began with the employment of horse-drawn chariots in battle.
