David Christian (historian)

• 1. Introduction

  ›

  David Gilbert Christian was born on the 30th of June, 1946, in Brooklyn, New York, to British and American parents. He grew up between Nigeria and England, educated at Atlantic College, an international sixth form in Wales, before earning degrees at Oxford and the University of Western Ontario. His doctorate, completed at Oxford in 1974, focused on nineteenth-century Russian history. Nothing in that biography would suggest he would one day stand before a TED audience introduced by Bill Gates, pitching a course that begins not with ancient Rome or the Renaissance but with the Big Bang itself.

  In 1989, Christian started teaching a course unlike anything on offer at any university. It asked students to sit with fourteen billion years of cosmic, geological, and biological time before getting to the part where humans show up. He called it Big History. How a Russian historian arrived at that idea, what it demands of its students, and why a Microsoft billionaire decided to fund its spread into secondary schools worldwide are the questions this documentary explores.

• 2. Russian Roots

  ›

  Christian's earliest research pointed nowhere near the cosmos. His doctoral work at Oxford examined nineteenth-century Russian history, and for years the peasantry of Russia and the Soviet Union defined his scholarly world. He was drawn to the texture of everyday life, the diet of ordinary people, the social weight of specific foods and drinks.

  In 1984, alongside co-author R. E. F. Smith, he published Bread and Salt, a social and economic history of food and drink in Russia. The book revealed how staples including bread, salt, and dairy products functioned as seasonings in peasant life, not merely as sustenance. It was the kind of granular, document-driven history that defined academic careers of that era.

  Christian began teaching at Macquarie University in Sydney in 1975, a post he would hold until 2000. During the 1980s, something shifted. He began reading widely outside his specialism, moving through cosmology, astronomy, and geology. He was looking for a frame large enough to hold all of human history, and the frame he found extended almost fourteen billion years in either direction from the present.

• 3. The Course That Changed Scale

  ›

  When Christian first taught his Big History course in 1989, it was genuinely novel. The subject drew on biology, cosmology, astronomy, geology, and anthropology to describe what happened before homo sapiens became prevalent on Earth. In a standard fifteen-week semester, humans typically did not appear in the material until the course was roughly halfway through.

  The approach required collaboration. Christian worked with scholars from across the sciences, social sciences, and humanities, each contributing expertise that no single historian could hold alone. Big History frames the human story inside cosmic and geological history, treating the emergence of life and civilisation as episodes in a much longer sequence.

  Christian's course eventually attracted the attention of The Teaching Company, whose Great Courses series selected it for distribution. He recorded forty-eight half-hour lectures for the series, and it became a best-seller. That commercial success placed his ideas in front of an audience far wider than any university classroom, including, eventually, Bill Gates.

• 4. Maps of Time

  ›

  In 1998, Christian published A History of Russia, Central Asia and Mongolia, a book that studied the steppe and forest peoples of Inner Eurasia rather than what he called outer Eurasia, the crescent of agrarian civilisations running from Europe through the Middle East and India to China. It was a significant scholarly work, but it still operated within recognisable boundaries of regional history.

  The book that arrived in 2005 was a different proposition. Maps of Time, a six-hundred-page volume published by the University of California Press, mirrored the content of his Big History course. A reviewer described it as a remarkable work of synthesis and scholarship. That same year it won the World History Association Book Prize. Christian had been named a Fellow of the Australian Academy of the Humanities in 1999, and Macquarie University designated him a Distinguished Professor in 2014.

  He transferred to San Diego State University in California in 2001, teaching world history, environmental history, and the history of Inner Eurasia, while maintaining affiliations with the University of Vermont and Ewha Womans University in Seoul. He returned to Macquarie in 2009.

• 5. Bill Gates and the Big History Project

  ›

  Philanthropist Bill Gates presented David Christian at the TED 2011 Conference in Long Beach, California. At that event, Christian announced the Big History Project, an initiative aimed at bringing the course to secondary-school students in Australia and the United States. Gates committed funding to support that expansion.

  The idea that a course beginning with the Big Bang could work for school-age students was not self-evident. Big History demands that students hold cosmological, geological, biological, and historical timescales simultaneously. Christian's argument was that this breadth produced a kind of understanding that narrow, document-based history could not.

  In 2010, the year before the TED announcement, Christian had written publicly about where he believed historical scholarship was heading. He predicted that over the next fifty years, academic history would return to what he called the ancient tradition of universal history, but in a new form that was global in practice and scientific in its methods. The Big History Project was his practical attempt to build that future from the classroom up.

• 6. A Discipline Taking Shape

  ›

  Christian is credited with coining the term Big History itself. He serves as president of the International Big History Association, the body that gives the field its institutional identity. The discipline he named has attracted its own scholarly infrastructure, journals, and conferences.

  His later books extended the project in different directions. Big History: Between Nothing and Everything, co-written with Cynthia Stokes Brown and Craig Benjamin, appeared in 2014 from McGraw-Hill Education. Origin Story: A Big History of Everything followed in 2018, published by Little, Brown and Company. A further volume, Future Stories: What's Next, appeared in 2022 from Little, Brown Spark, turning the Big History lens forward rather than back.

  The International Big History Association and the ongoing secondary-school programme represent the institutional legacy of a shift that began when a Russian historian at Macquarie University in Sydney started reading cosmology on the side and asked what would happen if a history course simply refused to begin in the middle of the story.
