Magnus IV of Sweden
The town of Falun is known to have existed in the 14th century as a market place for the surrounding lands. Mining for copper had been a local business since the mid-13th century, or possibly as early as 1000, and the organisation for the extracting of copper and gold from Stora Kopparberget is believed to be the oldest still-existing enterprise in the world, proved active since 1347, when its charter was granted by King Magnus IV of Sweden. The first share in the company is dated as early as 1288.
