About This Topic
The Birth of American Imperialism marks the period when the United States began to expand its influence far beyond its continental borders. This topic covers the motivations for expansion, including the desire for new markets and the belief in American exceptionalism. Students examine the Spanish-American War, the annexation of Hawaii and the Philippines, and the Open Door Policy in China, focusing on the intense debate between imperialists and anti-imperialists.
For 11th graders, this topic is essential for understanding the origins of the U.S. as a global superpower. It requires a critical look at how the nation's founding principles of self-determination were often ignored in the pursuit of empire. Students grasp these complex geopolitical shifts faster through structured debates on annexation and collaborative investigations into the role of 'yellow journalism' in shaping public opinion.
Active Learning Ideas
Formal Debate: To Annex or Not?
Students take on the roles of imperialists like Albert Beveridge and anti-imperialists like Mark Twain. They debate whether the U.S. should annex the Philippines, focusing on the moral, economic, and political arguments of each side.
Inquiry Circle: Yellow Journalism
Small groups analyze headlines and articles from the Hearst and Pulitzer newspapers leading up to the Spanish-American War. They must identify the techniques used to inflame public opinion and discuss the ethical responsibilities of the press.
Think-Pair-Share: The Open Door Policy
Students read the 'Open Door' notes regarding trade in China. They work in pairs to discuss how this policy served American economic interests while ignoring the sovereignty of the Chinese people.
Watch Out for These Misconceptions
Common MisconceptionThe U.S. only got involved in the Spanish-American War because of the sinking of the Maine.
What to Teach Instead
While the Maine was the 'spark,' the U.S. had long-standing economic interests in Cuba and a growing desire to assert its power in the Western Hemisphere. A 'causation map' activity helps students see the multiple factors that led to war.
Common MisconceptionThe people in the newly acquired territories were happy to be part of the U.S.
What to Teach Instead
In many places, especially the Philippines, there was intense and violent resistance to American rule. Peer-led analysis of the Philippine-American War helps students understand the reality of colonial resistance.
