So, with the rise of the copper age, new cultures were formed, and new forms of prestige appeared. Economy was emphasized too, with evidence of long trade routes. Moreover, it can be safely said that there was a greater emphasis on the warrior culture, especially in Europe. In archaeology, the first signs of massacres, battles, and warrior burials begin appearing with the rise of the Copper and Bronze Ages. The Copper Age did not begin at the same time all around the world. In many places this was an isolated process, appearing at roughly the same time in various corners of the globe. Nevertheless, a certain timeframe can be agreed upon, in that the Copper Age lasted from roughly mid-5th millennium BC, all the way to the late 4th, early 3rd millennium BC. At that time, people discovered that by adding tin to copper, a stronger and more durable metal could be created; Bronze. From that point on, the Bronze Age begins.
