Who came up with the idea that Elizabeth and Victor should marry?

The idea that Elizabeth and Victor should marry originated from Victor Frankenstein's father, Alphonse Frankenstein. He suggested the union as a means to strengthen family ties and solidify their social status. This proposal aligns with the expectations of their society, where marriage was often seen as a way to secure alliances and ensure stability. Ultimately, the engagement reflects the familial bonds and societal pressures that shape the characters' lives in Mary Shelley's "Frankenstein."
