Editor's Notes

  • #4 § US gained the Louisiana Territory, more than 800,000 square miles of land § US gained control of MS river § Native Americans did not recognize US “rights” to landàongoing conflict and more than 50 wars
  • #5 § sent by Jefferson to explore western part of continent § looking for water route across continent (which they didn’t find), to establish relationships with Native Americans (for access to the fur trade) § observed firsthand the impact of European settlement on Native American culture § expedition shifted the idea of “the West” westwardàcitizens began to settle further inland and view lands west of Mississippi as ripe for expansion
  • #6 § Missouri petitioned Congress to enter as slave state (at a time when Congress was balanced with 11 slave, 11 non-slave states) § MI able to enter as slave state b/c ME entered as free, maintaining the balance But draws the line of free and slave westward - will stay with new turf???
  • #7 § spearheaded by Andrew Jackson as a means to remove all Indian tribes then living east of the Mississippi River § goal of removal was furthered when govt dispossessed the native Americans of their land § “trail of tears” marked migration of Indians; removal was complete by 1844
  • #8 § resulting following a defeat at the Alamo § Anglo settlers were discontent with Mexican rule - also slaveowners but in Mexico where slavery outlawed § Mexican govt regarded annexation as declaration of war; never ratified TX independence
  • #9 § war was over the annexation of TX as a US state in 1845 § tremendously divisive: some saw as bid to add another slave state, some supported even more aggressive expansion into Mexico, some didn’t want to incorporate non-white citizens, some afraid of empire building § US victory in 1848: gained 1.2 million square miles of territory (what would eventually become CA, NV, UT, some of CO, WY, most of AZ and NM) § Land transfer reduced Mexico nearly by half, created lasting sense of resentment towards US
  • #10 § discovery of gold and subsequent “rush” to mine and otherwise capitalize on the discovery brought 300,000 + people to California § established San Francisco as thriving city led to the incorporation of California as a state (in the Compromise of 1850)
  • #11 § Oregon Trail and its many offshoots used by about 400,000 settlers, farmers, miners, ranchers, and business owners and their families. § 1869 – decline b/c transcontinental railroad completed
  • #12 § 10 years after Indian Removal, the govt began moving towards a policy of fencing native Americans within specified reservations to open up the West to expansion/white settlement § Indian Appropriations Act of 1851 was designed to consolidate western tribes on agricultural reservations
