History of Gold in Civilizations

These are links that point out to the role of gold throughout history. I have chosen sites that are more likely show the relation of gold to geopolitical and economic events like America's first Depression in 1800s. I hope this will be useful and please suggest other sites that focus on how gold affects power shifts around the world and trade wars.
