In the mid-17th century, a silk ribbon weaving industry became established in the local area which included Nuneaton, Bedworth, Coventry and much of North Warwickshire. This industry was enhanced by the arrival of French Hugenot immigrants in the latter part of the century, who brought with them new techniques. This industry operated as a cottage industry, with the weavers working from top-shops; a type of building which was specific to the local area, and had living space in the two lower floors, and a workshop with very large windows on the top floor. This industry flourished for nearly two centuries, albeit with periodic booms and slumps. However by the early 19th century the industry was struggling to compete against the factory produced textiles from northern manufacturers, and the local weavers strongly resisted adopting factory production methods as they valued their independence. Nevertheless, in 1851 46% of Nuneaton's workforce was still employed by the ribbon trade. The industry was finally wiped out after 1860 by cheap imports, following the Cobden–Chevalier Treaty, which removed duties on imported French silks. This caused a slump in the local economy which lasted nearly two decades.
