Bearing in mind the time at which William wrote these words, it will be seen that the Empress and her partisans must have largely, to say the least, based their claim on her right to the throne as her father's heir, and that she and they appealed to the oath as the admission and recognition of that right, rather than as partaking in any way whatever of the character of a free election.[94] Thus her claim was neatly traversed by Stephen's advocates, at Rome, in 1136, when they urged that she was not her father's heir, and that, consequently, the oath which had been sworn to her as such ("sicut hæredi") was void. It is, as I have said, in the above light that I view her unvarying use of the style "regis Henrici filia," and that this was the true character of her claim will be seen from the terms of a charter I shall quote, which has hitherto, it would seem, remained unknown, and in which she recites that, on arriving in England, she was promptly welcomed by Miles of Gloucester "sicut illam quam justam hæredem regni Angliæ recognovit." The sex of the Empress was the drawback to her claim. Had her brother lived, there can be little question that he would, as a matter of course, have succeeded his father at his death. Or again, had Henry II. been old enough to succeed his grandfather, he would, we may be sure, have done so. But as to the Empress, even admitting the justice of her claim, it was by no means clear in whom it was vested. It might either be vested (_a_) in herself, in accordance with our modern notions; or (_b_) in her husband, in accordance with feudal ones;[95] or (_c_) in her son, as, in the event, it was. It may be said that this point was still undecided as late as 1142, when Geoffrey was invited to come to England, and decided to send his son instead, to represent the hereditary claim. The force of circumstances, however, as we shall find, had compelled the Empress, in the hour of her triumph (1141), to take her own course, and to claim the throne for herself as queen, though even this would not decide the point, as, had she succeeded, her husband, we may be sure, would have claimed the title of king.
