From the simplest of throwing spears half a million years ago, to the sophisticated long-range projectiles of the twenty-first century, the history of weapons tells a fascinating story of our relationship with natural resources, each other and how our drive to survive ultimately shaped the modern world. Eventually humans turned their weapons on each other, putting their best minds to work refining and evolving their designs over the millennia to gain the upper hand. And while the first ranged weapons were used up close, the battle distance continued to grow, as conflicts for power, land, religion and riches spread across the planet. Today, the need for new and improved weapons shows no sign of stopping. Whether for good or for bad, these inventions are part of the human journey, traced back to the earliest ancient engineers.
