History Paper-M6D2 HISTORY

This discussion addresses the following outcomes:

• Define the concept of “Manifest Destiny” and examine its role in American expansionism into Texas and other Mexican territories. (CO#1, #3)
• Explain the significance of the Mexican-American War in the sectional controversy over slavery (CO#3, #5)

Expansion is a major theme of the United States’ history. As a young, energetic country, the United States also saw itself as gifted by Providence to spread out into neighboring lands. The migration of Americans into Mexican territory opened a new chapter in that story. Texan independence from Mexico seemed to fulfill the promise of Manifest Destiny, not just in terms of land but in the spread of American ideals. However, the Mexican-American War also unsettled a sectional balancing act regarding slavery.
