The widespread use of bronze had reached [[Scandinavia]] and the [[British Isles]] by 1500 BC. In [[sub-Saharan Africa]] cultures, the use of metals coincided with the widespread dissemination of iron.

Bronze is an alloy of [[copper]] and [[tin]]. In nature these are not normally found in the same area. (In antiquity, the British Isles were referred to as the “Tin Isles” whilst the name of the island of [[Cyprus]] has its roots in the word for “copper”.) Consequently it is natural that as bronze became more important, centers had to become more organized; and as trade routes were opened up between the sites of the respective metals, technology and knowledge flowed between cultures, hastening the spread of civilization. It is not an [[accident]] that there are links between the advent of bronze working and the introduction of writing in many areas. In many places it enabled the introduction of the plough.
