Not only historical ages, but some revolutions too were named after metals. Here is the story of one such revolution.
In 1662, Russia was in a state of unrest. The people were exhausted after a lengthy war with Poland and Sweden. In addition to that, Russians were faced with frequent crop failures, as a result of which, heavy taxes were imposed by the Czar, or ruler of Russia. It was during this time that the Russian government decided to begin issuing copper money in large quantities instead of silver money, which was already in existence.
The replacement of silver coins was followed by a sharp rise in the prices of bread and other foodstuff. Needless to say, the people of Russia were infuriated by the changing social situations. They rioted in response to the changes on July 25 1662, but the Czar put down the riots with an iron hand. Hundreds of people were killed and thousands were either sent to prison or exiled to Siberia.
