PART III – Essаy *Pleаse chооse ONE оf the following questions аnd provide a detailed response incorporating themes and events from lecture, as well as the primary documents from your readings. Also, be sure to identify and answer all parts of the question in order to receive full credit. 1.) Although the War of 1812 remains relatively overlooked in terms of its importance to American history, we’ve seen just how big of an obstacle it truly was to our fledgling nation. Using relevant examples and supporting evidence, briefly describe the origins of this struggle, as well as how the United States was able to avoid disaster in declaring war against the British Empire without detailed preparations. Finally, how did the conflict influence the nation in the decades that followed 1815 and what are some of the lasting legacies of this often overlooked war on American development? Be sure to support your argument with several key terms and examples from lecture and your readings. 2.) Perhaps no other individual has come to embody his era in American history more than President Andrew Jackson does in the 1820s and 1830s. Using several relevant examples and key terms from your reading and classroom lecture, briefly support this statement showing how Jackson’s background, persona, election, and political policies, came to embody the national identity during the first half of the 19th century. What factors contributed to his rise and how did he irreversibly change the face of American politics in his wake? Be sure to support your argument with several key terms and examples from lecture and your readings.
