Lampeter was first imcorporated under Edward II., but the earliest known charter dates from the reign of Henry VI., whereby the principal officer of the town, a portreeve, was to be appointed annually at the court-leet of the manor.
By this charter the burgesses acquired the right of nominating annually two of their number for the office of portreeve so that the lord's steward might select one of them to exercise the office, an arrangement which continued till 1835; the bailiff's functions were defined and curtailed, and the lord's chancery was to be continually kept open for all requiring writs, and in Gower - not wherever the lord might happen to be.
Cromwell's charter of 1655, though reciting that "time out of mind" Swansea had been "a town corporate," incorporated it anew, and changed the title of portreeve into mayor, in whom, with twelve aldermen and twelve capital burgesses, it vested the government of the twn.
Otto Bodrugan in 1320 granted the burgesses the privilege of electing their own portreeve and controlling the trade of the town.
Llanelly, though an ancient parish and a borough by prescription under a portreeve and burgesses in the old lordship of Kidwelly, remained insignificant until the industrial development in South Wales during the 19th century.
