National History Day



Theme:  Breaking Barriers in History

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 2020 is  Breaking Barriers in History.  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.
