Theodore’s union with Isabella
The Castle of OtrantoTheodore’s union with Isabella concludes the transfer of Otranto from Manfred’s family to its rightful heir, but the marriage is presented not as an instant reward for political restoration. Theodore first has to reckon with Matilda’s death; only through repeated conversations with Isabella does he come to accept companionship as compatible with mourning.
Political Background
The match emerges from a succession crisis in which Manfred had treated marriage as an instrument of rule. After Conrad’s death, he sought to divorce Hippolita and marry Isabella, presenting the arrangement as a way to secure sons and his dynasty. When Isabella could not be found, he ordered the castle’s exits guarded and restricted movement within it. His authority over his household thus became entangled with his claims over Otranto and its future.
Later, addressing the assembled knights, Manfred explained that Conrad’s death had made him consider giving up his dominions. He said that he had wanted a successor who would care for the people and had regarded Isabella as dear to him, while worrying that a ruler imposed from outside might govern harshly. He then proposed marrying Isabella as a way to end the feud between their families. The proposal repeats his effort to make private marriage serve political stability, even as the story ultimately places succession in Theodore’s hands.
Restoration and Abdication
Manfred’s final confession changes the basis of the succession. He acknowledges that Alfonso died by poison and that a fictitious will made Ricardo his heir. He also accepts the prophecy that Ricardo’s descendants would rule until the rightful owner grew too large to inhabit the castle, and concedes that the losses of Conrad and Matilda have left no other member of his line. Although he says he does not know how Theodore can be Alfonso’s heir, he accepts the judgment and relinquishes the principality.
The next morning Manfred signs his abdication with Hippolita’s approval. He and Hippolita take religious habits in neighboring convents, while Frederic offers Isabella to Theodore, now the new Prince. The political settlement therefore precedes Theodore’s consent: the offer is made once his right to rule has been recognized, but his personal response remains unsettled by grief.
Grief and Companionship
Theodore’s sorrow for Matilda is still too fresh for him to contemplate another love when Frederic makes the offer. His eventual union with Isabella follows frequent conversations in which they speak of Matilda. The account makes those conversations the bridge between loss and a new relationship: Theodore is persuaded that he can find happiness in Isabella’s company precisely because he can continue to give space to the melancholy that has taken hold of him.
The union consequently does not erase Matilda from Theodore’s story or present grief as simply over. Instead, Isabella’s companionship allows remembrance to remain part of his future. This personal resolution comes after Manfred’s confession and political surrender, linking the new ruler’s household to the restoration of legitimate succession without reducing his marriage to a dynastic arrangement alone.
