Debate & Diplomacy in History


Each year, National History Day® frames students’ research within a historical theme. The theme is chosen for broad application to world, national, or state history and its relevance to ancient history or to the more recent past. The 2021-2022 theme is Debate & Diplomacy in History: Successes, Failures, Consequences.
