Salt - History

History

While people have used canning and artificial refrigeration to preserve food for the last hundred years or so, salt has been the best-known food preservative, especially for meat, for many thousands of years. A very ancient saltworks operation has been discovered at the Poiana Slatinei archaeological site next to a salt spring in Lunca, Neamţ County, Romania. Evidence indicates that Neolithic people of the Precucuteni Culture were boiling the salt-laden spring water through the process of briquetage to extract the salt as far back as 6050 BC. The salt extracted from this operation may have had a direct correlation to the rapid growth of this society's population soon after its initial production began. The harvest of salt from the surface of Xiechi Lake near Yuncheng in Shanxi, China dates back to at least 6000 BC, making it one of the oldest verifiable saltworks.

Salt was included among funeral offerings found in ancient Egyptian tombs from the third millennium BC, as were salted birds and salt fish. From about 2800 BC, the Egyptians began exporting salt fish to the Phoenicians in return for Lebanon cedar, glass, and the dye Tyrian purple; the Phoenicians traded Egyptian salt fish and salt from North Africa throughout their Mediterranean trade empire.

In Africa, the Tuareg have traditionally maintained routes across the Sahara especially for the transportation of salt by Azalai (salt caravans). In 1960, the caravans still carried some 15,000 tons of salt a year but this trade has now declined to roughly a third of that figure.

Salzburg, Hallstatt, and Hallein lie within 17 kilometers (11 mi) of each other on the river Salzach in central Austria in an area with extensive salt deposits. Salzach literally means "salt water" and Salzburg "salt city", both taking their names from the German word Salz meaning salt. The equivalent Celtic word was Hall, and Hallstatt was the site of the world's first salt mine. The town gave its name to the Hallstatt culture that began mining for salt in the area in about 800 BC. Around 400 BC, the townsfolk, who had previously used pickaxes and shovels, began open pan salt making. During the first millennium BC, Celtic communities grew rich trading salt and salted meat to Ancient Greece and Ancient Rome in exchange for wine and other luxuries. The word salary originates from Latin: salarium which referred to the money paid to the Roman Army's soldiers for the purchase of salt. The word salad literally means "salted", and comes from the ancient Roman practice of salting leaf vegetables.

In 1930, Mahatma Gandhi led at least 100,000 people on the "Dandi March" or "Salt Satyagraha", in which protesters made their own salt from the sea, which was illegal under British rule, as it avoided paying the "salt tax". This civil disobedience inspired millions of common people, and elevated the Indian independence movement from an elitist struggle to a national struggle.
