But American expansion is not without its
problems - Expansion will bring about disputes both
within the US & with our foreign neighbors
Conflict with Great Britain
• Boundary line between Maine & British-controlled Canada was unclear
* Dispute w/ GB ends with = The Webster-Ashburton Treaty
The Oregon DisputeThe Oregon Dispute
Both the US & GB claimed Oregon
Treaty of 1818 = US and GB would have control of Oregon until issue could be resolved permanently
American settlement
• Mexico gains independence from Spain• → invites American settlers to TEJAS to develop territory
• 1st American settlers successfully led by Stephen Austin
* By 1830, Americans outnumber Mexicans in Tejas by 3 to 1!
Friction between American settlers & Mexican
government:* When….new rules to tighten Mexican control of Tejas:
Ban further American immigration 1829 – Mexico abolished slaveryAmericans (plantation owners) reaction--> --refused to follow these new regulations–Land hungry American southerners continued to stream into Tejas
Road to Texas Independence

abolished local self-rule! →
revolts break out across Mexico

Texas Independence
* Alamo 1836– Americans defeated* Goliad – Americans defeated again! Santa Ana’s soldiers execute any prisoners
* San Jacinto – Mexican defeat; Santa Ana captured & forced to recognize Texan independence
* Grants Texas all land north of the Rio Grande River
* BUT: Mexican gov’t still considers Texas a MEXICAN TERRITORY
Texas requests admission to Union
• Newly “independent” Texas faced financial problems →•Texas president Sam Houston requests admission to Union
• North = opposed to addition of more slave territory •Why? Texas if admitted could be made into as many as 4 or 5 states, particularly SLAVE states• This would upset balance between free & slave in Congress
• Texas not admitted yet; looks to Britain for help!!!
• President John Tyler (slaveowner) sees chance to annex this HUGE territory slipping away!
* Tyler works for annexation, but doesn’t get 2/3 vote for approval
The election of 1844: Texas becomes an issue!
* The candidates: Henry Clay = tried to avoid issue of annexationJames K Polk = openly in favor of expansion & manifest destiny–US should annex Texas & California –Demanded total American control of the Oregon Territory: “Fifty-four forty or fight!”
James K. Polk wins!
Texas is annexed
Lame-duck means: OUTGOING PRESIDENT; POLICIES ARE NOT REALLY THE FOCUS ANYMORE
Lame-duck President Tyler still works to annex Texas
Persuades Congress to annex Texas using a “joint resolution of Congress” → required only a simple majority (50%=1)
Mexico’s reaction--> fury! Anger! War is coming!!!!

Pres. Polk doesn’t want war with GB AND MEXICO– compromises with GB over US-Canada Boundary →now, it will be the 49th parallel instead of 54°40′
Orders US troops into disputed area between Texas and Mexico
