The Laws in Wales Act 1535 effectively abolished the powers of the Marcher Lords and divided the county into seven hundreds, roughly corresponding to the seven pre-Norman cantrefi of Dyfed. The hundreds were (clockwise from the northeast): Cilgerran, Cemais, Dewisland, Roose, Castlemartin, Narberth and Dungleddy and each was divided into civil parishes; a 1578 map in the British Library is the earliest known to show parishes and chapelries in Pembrokeshire. The Elizabethan era brought renewed prosperity to the county through an opening up of rural industries, including agriculture, mining and fishing, with exports to England and Ireland, though the formerly staple woollen industry had all but disappeared.
