History of Horror
The genre known as horror as we know it today did not officially start until around the 1600’s. The roots of modern day horror began with people believing in witchcraft. As that evolved, people began creating more and more horror until it evolved into what we now know as horror. 

The first well-known piece of literature the modern society considers
as horror is Frankenstein by Mary Shelley. The gothic novel is about what would happen if a scientist figured out how to manipulate life and death. This idea is still continued today with such ideas as the house of tomorrow.

Many other gothic novels followed
Frankenstein, but one American poet is still honored today for his gothic poetry. Edgar Allan Poe wrote his now famous poem, ‘The Raven’, in 1845. This is probably his most known piece.

Folk tales have always played a big part in horror. Many legends and tales are the basis for many horror movies.
Such as Rosemary’s Baby which was based on the legend of the devil baby of Hull House.
Without many other gothic works or scary folk tales we would never have the modern horror movie.
