2021 National History Day


Virtual Awards Ceremony, Friday, March 19, 2021 from 6:00 – 7:30 p.m. ​

Theme: Communication in History: The Key To Understanding

Each year NHD frames students' research within a historical theme. The theme is chosen for its broad application to world, national or state history and its relevance to ancient history or to the more recent past. The theme for 2021 is Communication in History: The Key To Understanding. The theme provides a focused way to increase  students' historical understanding and an opportunity to develop perspective and understanding rather than merely being able to cite facts and figures.​



Each year NHD establishes an annual theme. Students may begin to work on projects as soon as the NHD finals competition ends in mid-June. The theme is purposely broad so that nearly any topic will work. To learn more about this year's theme, go to Theme Sheet.
