THE MARCHER SHIRE OF PEMBROK AND THE GLYNDWR REBELLION IN the years since the publication of Sir J. E. Lloyd's classic studyTcwew Glendower (1931), the rebellion of Owain Glyndwr has attracted a considerable amount of attention, a notable feature of which has involved local studies. The course and consequences of the rebellion in the former counties of Anglesey, Cardigan, Carmarthen, Flint, Glamorgan, Radnor and, partially at any rate, in Denbighshire (Ruthin) have been discussed. It is perhaps to be expected that the majority of these studies concern localities which were under Crown control, either as part of the principality or the duchy of Lancaster. With the possible exception of Ruthin, the lordships of the march are not as well served by surviving evidence as are their royal counterparts. In this respect, the county palatine of Pembroke presents special problems; unlike its neighbours, the counties of the principality, it was neither as cohesive administratively nor as successful in preserving its records. The Marshal partition of 1247 had left the county as a single unit for jurisdictional purposes, but only the southern and north-eastern portions were actually held by the earl of Pembroke. Besides the earl's demesne lordships of Pembroke and Cilgerran, the county embraced some eleven other lordships, a number of independent ecclesiastical enclaves and seven seignorial boroughs, three of which-Haverfordwest, Pembroke and Tenby-were among the wealthiest in Wales.2 As a result, the study of Pembrokeshire during the rebellion cannot rely on any one major source, as did the studies of Ruthin and Flint. Nevertheless, recent research and a review of the available sources enables a coherent narrative and analysis of the rebellion in this hitherto neglected sector of medieval Wales to be written, A. D.
