The earliest known town twinning in Europe was between Paderborn, Germany, and Le Mans, France, in 836. Starting in 1905, Keighley in West Yorkshire, England, had a twinning arrangement with French communities Suresnes and Puteaux. The first recorded modern twinning agreement was between Keighley and Poix-du-Nord in Nord, France, in 1920 following the end of the World War I. This was initially referred to as an adoption of the French town; formal twinning charters were not exchanged until 1986.
