AP US History
Unit 5 – Civil War and Reconstruction, 1848–1877
Topic 5.3
How might American history look different if President James K. Polk failed in his attempts to initiate hostilities with Mexico?
America would be smaller compared to its present size due to lack of eastern expansion.
It would've delayed Louisiana Purchase and Lewis & Clark Expedition because of border tensions with Mexico.
America may not have gained much of its current southwestern territory through Treaty of Guadalupe Hidalgo.
There wouldn't be any significant effect on American history apart from a peaceful relationship with Mexico.
