Southerners and Westeners supported the war but Northerners aw it as Southern war of aggression
Texan Independence - American people
settled in Texas in 1820s. In 1829, Mexico
freed the slaves and banned further
immigration in Texas. American defied
both laws. The American Texas did not
like the President trying to enforce the
law and declared indpendence. The Army
marched in with President Santa Anna
but American from South and West came
and aided Texas which allowed the defeat
of the Army. Santa Anna was forced to
recognise the independence of Texas
Texas wanted to join USA but Northernes did not want it as
they feared the spread of slavery. Texas was big enough to
spilt up into five slave state which would tilt the balance. The
issue of Texas was shelved until 1845, when it was admitted to
Union as single state. This made Mexico angry. President Polk
sent John Slidell as emissary to offer 30 million dollars to
purchase New Mexico and California but the government
rejected it. Polk set US troop to provoke incident that would
cause war. Mexican troops ambushed American tropps. Polk
declared that Mecxican shed "American blood on American
soil" and declared war
