Ben and I began reading about the Mexican-American war in chapter 19 of his text this morning. We learned that James Polk's campaign promise of "Fifty-Four or Fight" meant that he supported moving the northern border of Oregon country, giving the US more land. We also read about the Oregon Treaty of 1846 which reset the borders between the US and Britain-controlled Canada, creating the Oregon territory. These events set the stage for the beginning of the Mexican-American war, about which we will read in tomorrow's session.
