It is well-known that Henry II, king of England, duke of Normandy
and Aquitaine and count of Anjou, added the duchy of Brittany to the
`Angevin empire' and granted it to his third son, Geoffrey. As the
necessary background to the con¯ict between the young Arthur of
Brittany, Geoffrey's posthumous son, and his uncle King John over the
succession to Richard the Lionheart, this is about as much as British
historians have felt they needed to know about Brittany in the twelfth
The history of the Angevin regime in Brittany has received only
scant attention from historians. This neglect has two causes; ®rstly, the
relative scarcity of contemporary sources, which makes the history of
Brittany in this period quite obscure, and secondly, the sentiments of
historians. Both British and French historians tend to overlook Brittany
as peripheral, backward, and, because of its Celtic history, different and
atypical. Whether the subject is the Anglo-Norman realm, the Angevin
empire or the Capetian monarchy, Brittany appears marginal, both
geographically and culturally.
Breton historians, for their part, have tended to avoid the period of
Angevin rule, passing over it as a shameful episode of foreign, and
worse, `English', domination best overlooked. When the topic cannot
be avoided, they have tended to emphasise baronial rebellion against
Henry II, characterising it as the heroic resistance of Breton patriots.1 In

Among the more impartial Breton writers on this subject are C. de la Lande de Calan, B. A.

Pocquet du Haut-Jusse and N.-Y. Tonnerre. Honourable mention must be made also of J. Le
Patourel, whose Channel Islands heritage enabled him to take a uniquely balanced view of
Anglo-Norman and Breton affairs (see Bibliography). I am extremely grateful to Professor Sir
James Holt for permitting me to consult in addition the following works from the unpublished
papers of Professor Le Patourel: `Plantagenet rule in Brittany to 1205' (1978) and `Guillaume

Brittany and the Angevins
‚ Á
feodale, xie-xiiie siecle (Rennes, 1987) the subject of `La mainmise
progressive d'Henri II sur la Bretagne' is dealt with in two pages
(pp. 86±8), while ®ve pages are devoted to baronial resistance (`Un

pouvoir dif®cilement accepte', pp. 88±93). Although these attitudes are
understandable, the central argument of this book is that they are
Furthermore, the effect of Brittany's near-absence from the historio-
graphy on the Angevin empire has been positively misleading. The
politics of Henry II and his sons cannot be understood without regard
to the time and resources they invested in acquiring and maintaining
lordship over Brittany. In particular, the political career of Henry II's
son Geoffrey is incomprehensible, an apparently irrational series of plots
and betrayals, if one ignores his career as duke of Brittany. Without an
understanding of the institutions of Breton government before Angevin
rule, it is impossible to judge whether Henry II and Geoffrey deliber-
ately introduced Anglo-Norman or Angevin institutions in Brittany.
In contrast with the dearth of material on Brittany under the
Angevins, the historiography of Brittany in the earlier middle ages, even
up to the late eleventh century, is thriving. Two monographs have
recently appeared on Carolingian Brittany.2 At the same time, several
Breton historians have focused their research on Brittany in the tenth
and eleventh centuries, and especially on the subject of the formation of
the nobility.3 The result of this work is to emphasise continuity in
Breton society through the ninth and tenth centuries.
The twelfth century represents something of a lacuna in the historio-
graphy of Brittany. There is no monograph on the subject of Brittany in
the eleventh and twelfth centuries, and few published articles. Recent
scholarship resumes at the end of the Angevin period, with two articles
on the life and reign of Duchess Constance.4
This lacuna can be explained, at least in part, because the twelfth
century falls in between two periods. It is too late for the period of the
formation of the post-Carolingian feudal society, which so interests the
current school of Breton medieval historians, and too early for the

`golden age' of ducal Brittany. This book aims to go some way towards
bridging the gap. Although there has been some work on Brittany and
the Angevins, no work has appeared on Angevin rule in Brittany in its
own right, rather than for the purposes of comparison with other
provinces or periods.5
Primary sources for Brittany in the twelfth century are scarce. The
scarcity is particularly conspicuous in literary sources. In contrast with
the eleventh-century `chronicles' of Nantes and Dol, no Breton
chronicles written in the twelfth century have survived, only monastic
annals.6 Breton historiography was revived in the late middle ages, but
the late `chronicles' or `histories' of Pierre Le Baud, Alain Bouchard and
the `anonymous of Saint-Brieuc' obviously are not reliable as primary
sources for the twelfth century.7 Yet it has recently been argued that
these authors were serious scholars, albeit politically motivated, and,
more importantly, they had privileged access to ducal and baronial
archives and drew on documentary sources which are no longer
extant.8 In this study, especially in Chapter 6, I have used Le Baud's
