Lovers' Vows (1798), a play by Elizabeth Inchbald arguably best known now for having been featured in Jane Austen's novel Mansfield Park (1814), is one of at least four adaptations of August von Kotzebue's Das Kind der Liebe (1780; literally "Love Child," or "Natural Son," as it is often translated), all of which were published between 1798 and 1800. Inchbald's version is the only one to have been performed. Dealing as it does with sex outside marriage and illegitimate birth, Inchbald in the Preface to the published version declares herself to have been highly sensitive to the task of adapting the original German text for "an English audience." Even so, she left the setting as Germany.
The play was first performed at Covent Garden on Thursday, 11 October 1798, and was an immediate success: it ran for forty-two nights, "making it by some distance Covent Garden's most successful venture of that season," and went on to be performed in Bristol, Newcastle, Bath, and elsewhere. It was likewise successful as a print publication, though it also aroused controversy about its "levelling" politics and moral ambiguity. Anne Plumptre, who translated Kotzebue's play as The Natural Son, wrote (perhaps not disinterestedly as the production of Inchbald's work effectively precluded the production of her own) that Inchbald had transformed the character of Amelia into a "forward country ." Others, however, defended the morality of the play. And indeed, various characters indulge in considerable moralizing about charity, honour, and forgiveness.

Act I: The play opens with Agatha being ejected from an inn when her money runs out. Too proud to beg, she is desperate. Frederick enters, sees her, and offers her money although it will mean he cannot pay for his own breakfast. She recognizes him as her son, absent for five years as a soldier. He has returned in order to find his birth certificate, necessary in order to find employment. Distraught, Agatha tells him that there is no certificate: she was seduced at the age of seventeen by Baron Wildenhaim upon promise of marriage. Despite the resulting pregnancy, the Baron broke his promise and married another, wealthier woman, and Agatha, turned out of her home, struggled to make ends meet and raise her son alone. Frederick is dismayed at the news, and to find his mother so destitute, and he arranges for her to stay with some charitable cottagers.
