Lancashire Legends, Traditions…
“ One of the most ancient pageant festivals in the kingdom is held in the borough of Preston every twenty years, under the designation of the "Preston Guild Merchant." The guilds were of Anglo-Saxon origin, and Camden describes the Gilda Mercatoria as a liberty or privilege granted to merchants, whereby they were entitled to hold certain pleas of land and other possessions within their own precincts, and whereby neighbours enter into associations, and become bound to each other to bring forth him who commits any crime, or to make satisfaction to the injured party. ”
