Salford began to emerge as a small town early in the 13th century. In 1228, Henry III granted the caput of Salford the right to hold a market and an annual fair. The fairs were important to the town; a 17th-century order forced each burgess – a freeman of the borough  – to attend, but the fairs were abolished during the 19th century. The Earls of Chester aided the development of the caput, and in 1230 Ranulf de Blondeville, 6th Earl of Chester made Salford a burgage, or free borough. The charter gave its burgesses certain commercial rights, privileges and advantages over traders living outside Salford; one of the 26 clauses of the charter stated that no one could work in the Hundred of Salford unless they also lived in the borough. Salford's status as a burgage encouraged an influx of distinguished families, and by the Late Middle Ages Salford was "rich in its manor houses", with over 30 within a radius of Ordsall. These included Ordsall Hall (owned by the Radclyffe family) and Broughton Hall, owned by the Earls of Derby.
