Suggested Teaching Instructions

 

As the nation expanded, growing sectional tensions, especially over slavery, resulted in political and constitutional crises that culminated in the Civil War. American nationalism was both strengthened and challenged by territorial expansion and economic growth. 

Students will examine the market revolution, including technological developments, the development of transportation networks, the growth of domestic industries, the increased demands for free and enslaved labor, the changing role of women, and the rise of political democracy
