Manifest Destiny and the Mexican-American War

 

TEXAS BECOMES THE TURNING POINT FOR WAR WITH MEXICO

Texas was originally a Mexican colony, though settled by freelance American pioneers; ultimately, they chose to be annexed by the United States, thus, provoking war with Mexico.

“…it will come to pass that the Anglo-American race will give this great continent as an inheritance to men…This national policy [expansion] necessity or destiny, we know to be just and beneficent…”
--from an editorial, NY Morning News, Oct. 13, 1845 on annexation of Texas (Merk 25).
*underlines American Nationalism and Westward Expansion as justification for the annexation of Texas


-The Adams-Onis Treaty: all of Texas belonged to Spain

-Successful 1821 Mexican Revolution against Spanish colonial power caused Mexico to inherit the Treaty

-Texas, sparsely occupied and decrepit from the Revolution, had high demand for skilled settlers to rehabilitate that land.

-Stephen Austin, American, and Erasmo Seguin had Mexican authorization emigrate American settlers

1820s: 1500 immigrant American families in Texas, for new opportunity with "manifest destiny"

-1836: Anglo-American population outnumbered Hispanics 10 to 1

“The old Latin mistake had been repeated,” said historian Frederick Merk: “admitting Gauls into the Empire” (Howe 660).

-
1833: General Santa Anna was elected dictator of Mexico; called himself the Napoleon of the New World

-
1835: Texans rebelled, after Mexicans abolish slavery, to reinstate the 1824 democratic Mexican Constitution

-1836: Texas, independent as a republic after Santa Anna was personally captured in the Texan Rebellion

Texas under threat of Mexican retaliation  had an ultimatum:

1) Texas could be annexed by USA and protected.

2) Texas could remain independent but vulnerable to immediate Mexican attack.

-1845: James K. Polk elected President; an imperialist whose dogma was Manifest Destiny and approved Texas annexation
