War has been “creative force” behind civilisation, scientists claim

Intro:

War has been the “driving force” which has created the societies we live in today, a new study claims.

Over 3,000 years, war – and in particular, warriors on horseback – have spread “civilisation” across the world, according to a new study.

Innovations such as farming technologies or writing are not enough to “spark” changes in society by themselves – chariots, cavalry, fire and the sword spread these ideas across the world.
