The Cambridge World History: Volume 1, Introducing World History, to 10,000 BCE

David Christian is by training a historian of Russia and the Soviet Union. He taught Russian and Soviet History at Macquarie University in Sydney, and conducted research on the diets of the nineteenth-century Russian peasantry and in particular on the role of vodka in Russian society and fiscal systems. In 1989 he began teaching a history course surveying the history of the Universe and placing human history within that larger context. This approach has since come to be known as 'big history', and it led to an increasing interest in world history, particularly in world history at very large scales. David Christian is the author of Maps of Time: An Introduction to Big History (2011), and co-founder with Bill Gates of the Big History Project (bighistoryproject.com), which has created a free online big history course for high school students. He is currently completing the second volume of a synoptic history of Inner Eurasia, the lands at the heart of the Eurasian landmass, from prehistory to the present day.
