Alien invasion
Meaning
The arrival of extraterrestrial beings on Earth, usually with hostile intent to conquer or destroy.
Origin
The concept of hostile extraterrestrial visitors gained significant traction with H.G. Wells's seminal 1898 novel, "The War of the Worlds." Before Wells, imaginative tales of beings from other planets were rare, often depicting benevolent visitors or fanciful encounters. Wells's vivid depiction of technologically superior Martians arriving in cylindrical capsules, laying waste to London with heat rays, and possessing a ruthless agenda, ignited the public's imagination and fear. This single, powerful narrative not only popularized the term "alien invasion" but also established many of the genre's enduring tropes, from advanced weaponry to humanity's desperate struggle for survival against an otherworldly threat, forever cementing it as a cultural touchstone for existential dread.
Examples
