At first glance, these two cards may have nothing in common. But in fact, they are linked by a mineral vital to all our lives:

UNESCO lubeck gate

This is the city gate from the Hanseatic City of Lubeck in Germany. This card was sent by Steffi. Lubeck has been a UNESCO World Heritage site since 1987.


India salt

This card comes from Georgy in India and shows salt pans in Tamilnadu.

Now, if you are wondering what a city in Germany has to do with salt pans, the answer is salt! I’ve been reading a book called Salt: A World History by Mark Kurlansky. According to Kurlansky, the Hanseatic League, which was a prominent confederation of merchant guilds in the Middle Ages, was formed in large part because of the profitability of the salt trade. Salt also played an important role in the Indian independence movement; in 1930, Mahatma Gandhi led a march to the sea to produce salt and protest the British salt monopoly, and symbolically British rule in general.

Thanks so much to Steffi and Georgy for the great cards!
