INSTRUCTIONS:
* Structure your exam in the following way:
one short paragraph for your introduction (2 or 3 sentences): here you mention that expansionism and imperialism were at the center of the 19th-century process of nation-building in the US, and that it affected Hispanic communities of Mexico and the Caribbean whose lands were annexed. Yet you can also suggest that some Hispanic communities living in the borderlands favored annexation as it advanced their economic interests.
one or two paragraphs where you explain the national ideology of US expansionism (Monroe Doctrine and Manifest Destiny), the role of filibusters, and the results of the Mexican-American War of 1848. However, you should also discuss how local communities of Texas and New Mexico experienced their annexation to the US and favor that process to advance their economic interests.
one paragraph where you discuss the process of the Americanization of Puerto Rico. Here you can discuss the Foraker Act of 1900 (the Executive Council), the education under the Foraker Act, and the political reforms under the Jones Act of 1917.
one short paragraph where you stress your main points and conclusions.
