Identify the economic, political, and social motives behind the New Imperialism of 1870-1914 and explain how new technology made rapid conquest possible.
Europeans had traded with and settled parts of Africa, Asia, and the Americas for centuries, but the "New Imperialism" of roughly 1870 to 1914 was different in scale and intent: industrialized powers now sought direct political control over vast territories, not just coastal trading posts. The Second Industrial Revolution's factories needed raw materials -- rubber, cotton, tin, palm oil -- and new markets to sell finished goods and new places to invest surplus capital, giving colonization a powerful economic motive. National prestige mattered just as much: European powers competed for colonies partly to outdo each other, seeking naval bases and what Germany's Kaiser called "a place in the sun."
A third motive was social and cultural: many Europeans, absorbing Social Darwinism from week 7, genuinely believed their own race and civilization were superior and had a duty to rule and "civilize" others -- a belief the British writer Rudyard Kipling captured in his 1899 poem "The White Man's Burden," which urged the United States to "take up" the supposed responsibility of ruling the Philippines. None of this would have been possible without a widening technology gap: the Maxim gun (an early rapid-fire machine gun) gave small European forces overwhelming firepower against much larger armies, quinine allowed Europeans to survive malaria and push into tropical Africa's interior for the first time, and steamships and the telegraph let distant colonial governments be supplied and controlled from thousands of miles away.
Mastery looks like: They can name all three categories of imperialist motive with a specific example of each, and explain how a primary source like Kipling's poem reveals a mindset even when one-sided.
Common stumbles: Reducing imperialism's causes to greed alone, missing the political and ideological motives, or treating "The White Man's Burden" as a factual description rather than a persuasive primary source revealing one era's worldview.
