The Horse, the Wheel, and Language: How Bronze-Age Riders from the Eurasian Steppes Shaped the Modern World is a 2007 book by the anthropologist David W. Anthony, in which the author describes his "revised Kurgan theory." He explores the origins and spread of the Indo-European languages from the Pontic-Caspian steppe throughout Western Europe, Central Asia, and South Asia. He shows how the domesticated horse and the invention of the wheel mobilized the steppe herding societies in the Eurasian Steppe, and combined with the introduction of bronze technology and new social structures of patron-client relationships gave an advantage to the Indo-European societies. The book won the Society for American Archaeology's 2010 Book Award.
