The market legally began in 1154 when Peter de Bermingham, a local landowner, obtained a Charter of Marketing Rights from King Henry II. Initially, a textile trade began developing in the area and it was first mentioned in 1232 in a document, in which one merchant is described as a business partner to William de Bermingham and being in the ownership of four weavers, a smith, a tailor and a purveyor. Seven years later, another document described another mercer in the area. Within the next ten years, the area developed into a leading market town and a major cloth trade was established.
