Hemp is distinguished by its rapid growth. As well as its ability to absorb CO2 and its beneficial role in soil structure. Its deep roots help prevent weeds, thereby reducing the need for herbicides.
The history of hemp in the world
From antiquity to the 16th century
Hemp is an ancient plant that dates back thousands of years. Evidence of its use goes back at least to the third millennium BC and possibly to the Neolithic Pre-Ceramic period (8800-6500 BC), according to archaeological evidence. As an ambassador of agriculture since the Neolithic, hemp was used for its strong fibers, particularly in producing ropes and fabrics. This versatile plant was used in India, Persia, Egypt, Greece, and even China, where, as early as the 5th millennium BC, its fibers penetrated the pottery of the Yangshao culture. In the Middle Ages, “agricultural hemp” was an economic mainstay in Europe, strongly promoted by personalities such as King Henry VIII of England for its use by the English navy.
The golden age of hemp in the 17th and 18th centuries
These centuries saw “industrial hemp” shine, crucial for Europe’s maritime supremacy. The sailing navy and its ships, including those of Christopher Columbus in 1492, were equipped with sails and rigging made of hemp. The increasing demand of the navies made the plant a strategic material, especially in France under the reign of Louis XIV, where cultivated hemp was strongly encouraged for industrial production.
Decline of hemp in the textile industry between the 19th and 20th century
The petrochemical era, which began around 1850, replaced hemp with wood in paper production. Influenced by the extensive forest resources of Canada and the United States. Hemp production was banned in the United Kingdom in 1928 and France after World War II, marking the beginning of its decline in Europe.
The marijuana “Tax Act” and its impact on the industry in the 20th century
The Marijuana “Tax Act” of 1937 banned the cultivation of hemp in the United States despite its everyday use in the American pharmacopeia. This legislation significantly contributed to the diversion of its use and replaced it with other raw materials.
Genetic crossbreeding with low THC content
In the 1970s, analysis and technical innovations made it possible to better distinguish between industrial hemp and Cannabis. This paved the way for a gradual rehabilitation of the plant. Today, France is the leading producer in Europe.
