In an Elizabethan account of Glamorgan towns, Cardiff was ‘the chiefest and therefore accounted the shire town’. Except where it bordered the River Taff, it was a walled town, and with a certain amount of local chauvinism Rice Merrick described it as ‘very well compacted, beautified with many fair houses and large streets’, on one of which stood ‘a fair town hall’.
In theory Cardiff, with its seven contributory boroughs, was the most complex Welsh borough constituency. It was not so in its political pattern, as five of the seven, as well as Cardiff, had been under the patronal control of the Herberts, earls of Pembroke, from the mid-sixteenth century: Swansea and Loughor, in Gower, were swayed by the Somersets of Raglan, but apparently offered no competition to the Herberts. Even so, the contributory boroughs continued to play a part in the elections of the 1620s, as the names of burgesses from some of them are recognizable on indentures from 1621, 1624 and 1626. All elections for the seat in the period 1604-29 appear to have been held in Bridgend, located in the middle of Glamorgan, to better enable participation from the more western boroughs of Aberavon, Loughor, Neath and Swansea.
William Herbert I of Cogan Pill, a second cousin twice removed of Philip Herbert*, 4th earl of Pembroke, lived three miles west of Cardiff and followed in the footsteps of his grandfather Nicholas Herbert and his cousin William Herbert of the Friars, Members for Cardiff in 1584 and 1621 respectively. His return attracted the attention of the clerk of the crown in chancery or perhaps the privileges committee, as it was noted that Herbert had been described on the indenture, wrongly, as mayor. By convention, serving mayors were not eligible to stand for election to Parliament, but what caused the indenture to be amended by the sheriff was the error of describing Cardiff as a ‘mayor town’.
From September 1642, Cardiff was in royalist hands, and remained so under successive governors until after Naseby, when the king’s attempt to maximise the potential of south-east Wales for supply of revenue and men induced first a recalcitrant show of defiance by a ‘peaceable army’ (July 1645) outside Cardiff, and then on 17 September 1645 the surrender of Cardiff to the same clubman force, which seemed by December to have been won over to Parliament. A short-lived revolt against parliamentary rule was crushed on 18 February 1646.
Sydney retained his seat until Oliver Cromwell* expelled the Rump Parliament in April 1653. In the revised electoral arrangements that pertained under the Instrument of Government, Cardiff was allocated a single seat, while Glamorgan had two, and the contributory boroughs were disenfranchised. Haverfordwest was the only other Welsh borough to retain separate representation at Westminster. The logic dictated that elections would henceforth take place in the borough, not elsewhere, and the first to be held under the Instrument took place on 12 July 1654. About 30 aldermen and burgesses put their names to the indenture.
