In a break with our regularly scheduled podcast, this Head on History Special peaks behind the curtain of professional history to covers the latest controversy with AP World History. Starting with a brief coverage of the news that College Board will restructured AP World History to only cover and test history post-1450, we dive into the deeper history of the field of world history. We go over the rough historiography of world history, the rise of the new discipline, it's relationship to Western Civilization courses, and why it matters a field. We discuss the importance of history as identity-shaping and why changes in World History are problematic. We also present the background of College Board. Join us for a historiography and discussion about the debate and controversy behind world history as a field and in our public education system.
