Year Without a Summer - Wikipedia, the free encyclopedia:
The crop failures of the “Year without Summer” forced the family of Joseph Smith to move from Sharon, Vermont to Palmyra, New York, precipitating a series of events culminating in the publication of the Book of Mormon and the founding of the Church of Jesus Christ of Latter-day Saints.
In July 1816 "incessant rainfall" during that "wet, ungenial summer" forced Mary Shelley, John William Polidori and their friends to stay indoors for much of their Swiss holiday. They decided to have a contest, seeing who could write the scariest story, leading Shelley to write Frankenstein, or The Modern Prometheus and Polidori to write The Vampyre.
The Year without a Summer also inspired Lord Byron to write his 1816 poem Darkness.
