What were the circumstances inspired to write Frankenstein?

Mary Shelley was inspired to write "Frankenstein" during the summer of 1816, when she and a group of writers, including Lord Byron and Percy Bysshe Shelley, were staying at the Villa Diodati near Lake Geneva. Due to unusually cold and stormy weather, they were confined indoors, leading to a storytelling contest about ghost stories. This prompted Shelley to dream of a scientist who creates life, reflecting contemporary themes of scientific exploration and the ethical implications of playing God. The combination of personal loss, philosophical debates, and the Romantic era's fascination with nature and the sublime influenced her creation of the novel.
