The concept of orcs, on the other hand, gained popularity through the works of J.R.R. Tolkien, particularly in his epic fantasy novels "The Hobbit" (1937) and "The Lord of the Rings" (1954-1955). Tolkien drew inspiration from various mythological sources, including Norse and Germanic folklore, to create his complex world called Middle-earth. His version of orcs were described as humanoid creatures, often portrayed as brutish and warlike, serving as minions to powerful dark lords like Sauron, the main villain in his tales.
