To coincide with the commemoration of the 250th anniversary of the Declaration of Independence, NHD’s 2026 theme is Revolution, Reaction, Reform in History. The distinctions among revolutions, reactions, and reforms are sometimes blurred. Revolutions and reforms are often reactions to ideas, actions, or events. In turn, revolutions and reforms inspire reactions. Think of it as a domino effect—knock one down, which knocks the next one down, which knocks . . .
The first question that comes to mind is, “Do students have to focus on all three words—revolution, reaction, reform?” No, students do not have to focus on all three aspects of the theme. It depends on the topic. If the topic involves all three, then students should be sure to include all three.
To get started, watch the Theme Video and complete the Theme Brainstorming Sheet. Then download and read the Theme Book.
National History Day in Minnesota kindly shares its annual theme presentation with all affiliates. To access the slides, you must fill out a request form so they can track usage. You may share the presentation with your students, but please encourage other teachers to complete the form too. They also ask that you do not post direct links to the presentation on any public websites or record your own versions of a screen recording.
