William Stubbs,
The early Plantagenets
(1900)
“ The feudal rights of Aquitaine—the right, that is, to demand homage and service—extended far beyond the limits of the sovereign authority of the dukes, and it was always an object to turn a claim of overlordship into an actual exercise of sovereign authority. The tie between the great county of Toulouse and the duchy of Aquitaine was complicated both by legal difficulty and by questions of descent. The rights over Auvergne, claimed by both the king and the duke, were so complex as to be the matter of continual arbitration, and at last were left to settle themselves. ”
