periods involves a large part of the Eurasian continent. Culture and change must be understood as both localised and macro-regional: the book is a cultural-historical tale - inspired by, for example, the attempts of French historians to integrate different levels of history.Emphasis is laid on the eventful boom periods where innovations and cross-cultural interaction intensified in such a way that history's mainly reproductive pattern was broken. Important turning points are attached, among other things, to the first production of food, copper- and bronze metallurgy, and the sword as a weapon and symbol. These technical innovations were part of a complicated interaction with social and cultural processes, which in many cases are connected in a pattern that can be followed in time and space.
