The Kurgans did it
"The holistic ideology of Old Europe was challenged and eventually overrun by the forefathers of the Indo-Europeans, the late Neolithic Kurgan culture that originated on the steppes of Russia. The Kurgan culture, with its horse-riding warriors armed with lethal weapons, brought into Europe an ideology based on patriarchy, hierarchy and military prowess. Their pantheon of gods was male-dominated and headed by a sky god. The Earth Goddess and other female deities were, under the new order, reduced in status to become merely the wives of the gods. Sexual inequality, militaristic violence, dualistic thinking and a fundamental belief in linear continuity (all features integral to our own civilisation) are found in Kurgan culture and amongst the later Indo-Europeans. The Stone Age philosophy of Old Europe, with its emphasis on cyclic time and holistic social and ecological thinking, was pushed aside as the new ideology gained ascendancy. The beliefs of Old Europe suvived as an undercurrent but the foundations of a new and savage civilisation were beginning to be built."
