Linen is one of the world's oldest cultivated fabrics, made from the sturdy fibres inside the stalk of the flax plant (Linum usitatissimum). Humans have used flax fibres for over 10,000 years. Ancient Egyptians mastered linen weaving around 5,000 BCE, using the pale, breathable cloth as currency, status symbols, and mummy wrappings due to its perceived ritual purity. In Medieval Europe linen served as foundational infrastructure for everyday life. By 789 CE, French king Charlemagne decreed that all households must cultivate flax and weave their own textiles. It was used for undergarments, bedding, towels, and sailcloth. Regions like Flanders became major production hubs by the 13th century.
The invention in 1793 of the cotton gin (engine), a machine that quickly separated cotton fibres from their sticky seeds made cotton cheaper and faster to process than hand-worked linen. By the mid-19th century, industrial cotton and later synthetic fibres largely replaced linen's dominance in daily fashion and households.
