Manfred's Attempt to Marry Isabella

Manfred’s Attempt to Marry Isabella is the ruler’s effort to replace his dead son’s dynastic marriage with a marriage to Isabella himself, an act that makes his struggle to secure an heir inseparable from his abuse of authority. His proposal sets private desire against marital and religious obligations, while the surrounding claims to Otranto expose the instability of the succession he is trying to preserve. Isabella resists, supernatural signs interrupt Manfred’s pursuit, and the Friar refuses to help him dissolve his marriage to Hippolita. The attempt ultimately fails alongside Manfred’s claim to rule.

Causes and dynastic purpose

Conrad’s death creates the immediate crisis. Manfred had expected his son’s marriage to Isabella to strengthen the future of his house; after the loss, he tells Isabella that she has lost her bridegroom and that he has lost the hopes of his race. He dismisses Conrad as too frail to support the family’s future and recasts the death as potentially beneficial, because he can now seek a husband capable of producing the numerous heirs he wants.

Manfred’s proposal follows directly from that calculation. He tells Isabella that, instead of marrying a sickly boy, she will have a husband in the prime of life who can value her and expect many children. When she asks to remain in the castle until her father returns, offering to comfort Manfred’s family in their grief, he refuses her appeal to patience and declares that he offers himself in place of his son. His stated objective is dynastic continuity: he says his fate depends on having sons and treats the marriage as the means to secure them.

The political premise behind this urgency is itself contested. Manfred maintains that Otranto passed from his father to his grandfather, Ricardo, after Alfonso died childless in the Holy Land and left his estates to Ricardo in recognition of his services. Frederic’s herald, by contrast, calls Manfred a usurper and demands both Isabella’s return to her father and the surrender of Otranto to Frederic, whom the herald describes as the nearest blood relative of the last rightful ruler. Manfred’s attempt to marry Isabella thus takes place amid competing claims over both her person and the principality.

Isabella’s refusal and escape

Isabella first answers Manfred’s proposal with disbelief. She stresses that he is Conrad’s father and Hippolita’s husband, and that she had understood herself to be a prospective member of his family through her engagement to Conrad. His answer is to insist that Hippolita is no longer his wife and that he will divorce her. The proposal therefore depends not only on replacing Conrad but on discarding Manfred’s existing marriage.

When Manfred tries to make Isabella accept his decision, she breaks away and cries out that Heaven opposes his intentions. At that moment the giant helmet appears in the moonlit window, its plumes moving as a supernatural disturbance. Manfred refuses to take the sign as a reason to stop. After the apparition leads him away and a chamber door shuts against him, he resolves to use human means to keep his family in power and says Isabella must not escape.

Isabella nevertheless continues her flight through the castle. She knows that its gates are locked and guards stand in the courtyard, and weighs whether to seek Hippolita or avoid drawing Manfred’s pursuit toward her. Her immediate objective is to evade his plan for that night. The attempt thus changes her position from a protected prospective bride to a fugitive within the castle, while Manfred’s determination makes the household itself unsafe for her.

Manfred’s demands and the Friar’s refusal

Manfred tries to turn his personal plan into a matter of state. In private, he tells the Friar that the principality’s safety and the need for a son require him to marry Isabella. He orders the Friar to bring her back and use his influence over Hippolita to secure her consent to the dissolution of their marriage. He even offers the possibility that Hippolita could retire to a monastery and endow it, presenting religious provision as a way to obtain the consent his plan requires.

The Friar rejects the arrangement. He identifies Manfred’s proposed divorce as an injury to Hippolita and the intended marriage to Isabella as incestuous, since she is already contracted to Manfred’s son. He will not betray the confidence Hippolita places in him or exchange his integrity for Manfred’s promises. Instead, he argues that neither political necessity nor the desire for an heir can make an unlawful marriage succeed, and warns that the disasters in Manfred’s family should prompt submission rather than further attempts to secure power.

The Friar’s refusal leaves Manfred without the religious and household cooperation he sought. Hippolita, meanwhile, remains a source of moral resistance: she has gone to the convent, and the Friar is urging her not to yield to a divorce. Manfred interprets her absence as a possible effort to obstruct his plan and hurries to the convent, where he finds her with the Friar. His attempt has therefore broadened from a proposal to Isabella into a campaign to overcome Hippolita’s resistance and enlist the Church in making the marriage possible.

Failure and political reversal

Isabella’s escape and the Friar’s refusal do not immediately end Manfred’s efforts to consolidate his position. He later proposes a double marriage linking the houses of Otranto and Vicenza, offering Matilda to Frederic while seeking to marry Isabella himself. Frederic is attracted to Matilda and sees the proposal as a possible route to succession, although he makes Hippolita’s consent to divorce a condition, if only formally. Manfred assumes that he can obtain that consent.

His pursuit of this arrangement is overtaken by the truth about the succession. In his final confession, Manfred admits that Alfonso died by poison and that Ricardo’s will naming him heir was fictitious. He recounts Ricardo’s vow to Saint Nicholas and the prophecy that Ricardo’s descendants would rule only until the rightful owner grew too large to inhabit the castle, while male heirs of Ricardo’s line remained. Manfred recognizes that his family’s losses and expulsion fulfill the judgment against its rule, and relinquishes the principality to Theodore.

Manfred signs his abdication the following morning; he and Hippolita enter religious life in neighbouring convents. Frederic offers Isabella to Theodore, but Theodore, still grieving Matilda, does not accept another love at once. After repeated conversations with Isabella about Matilda, he comes to believe he can find happiness in her company while continuing to mourn. The marriage Manfred tried to impose never takes place: his bid to secure the dynasty by taking Isabella gives way to confession, renunciation, and the recognition of a rightful successor.
