Invasion theory or Invasionism is a method of explaining changes in past societies that relies on the idea of external conquest to provide the catalyst for new ideas appearing in a culture, cite book| last = Smith| first = Anthony D. | title = The Concept of Social Change: A Critique of the Functionalist Theory of Social Change| publisher = Routledge | date = 1973| pages = 157-158| url = http://books.google.com/books?id=h649AAAAIAAJ&pg=PA157&dq=invasionism&sig=UpCBKVJZF613PxRFTqkHXzm-X5o#PPA157,M1| isbn = 071007607X ] for example, the arrival of novel artefact types or building styles appearing in the material record.

It is connected with early twentieth century ideas of diffusionism and hyper-diffusionism which often hinged on Biblical mass folk movements and successive waves of invaders providing infusions of new ideas in different regions.
