When it was first suggested in 1956, Marija Gimbutas's answer to the question of Indo-European origins was a pioneering interdisciplinary synthesis of archaeology and linguistics. From the nineties on, new archaeological evidence from Northern European prehistoric cultures was put forward on the influence and expansion of Kurgan cultures.
