Origins and history of the mulberry tree: from silk to modern fruit production

The history of the mulberry tree is closely linked to that of sericulture , the breeding of silkworms. Native to Asia , the mulberry tree has played a crucial role in the economic and cultural development of many civilizations.

Asian origins

The earliest evidence of mulberry cultivation dates back to ancient China , more than 4,000 years ago. The white mulberry (Morus alba) , in particular, was cultivated for its leaves, which were used to feed silkworms . Legend attributes the discovery of silk to Empress Xi Ling-Shi , who observed a cocoon fall into her teacup under a mulberry tree.

Silk Road Broadcasting

Mulberry cultivation gradually spread along the famous Silk Road , reaching the Near East during the Middle Ages. In Europe, the first white mulberry trees are mentioned in Provence in the 13th century , marking the beginning of the silk industry in Western Europe .

Development in France

In France, silk production first developed in Provence and the Cévennes during the Middle Ages and the Renaissance. In the 16th century, under the leadership of King Francis I , mulberry cultivation spread to the Lyon region. It was at the beginning of the 17th century that sericulture really took off in France.

Expansion policies
