II. Politics in Mexico

• Mexico plagued by chronic political instability

• 1821-1871- 50 Mexican presidents in office

• Political factions: Centralists, Federalists,

• Mexican politics prevents consistent approach to problems with Texas Revolt and Polk administration

The Texas Revolt

A. Permission to settle:

Starting in 1821, Spain and then an Independent Mexico had granted permission to

Catholic (North) Americans to settle the sparsely populated territory of Texas.

B. Incentives for settlement:

Soon there was a great influx of Americans settlers into Texas. The land was practically

free--only 10¢ an acre as opposed to $1.25 an acre for inferior land in the U.S. Each male

colonists over twenty-one years of age was allowed to purchase 640 acres for himself, 320

acres for his wife, 160 acres for each child and, significantly, an additional 80 acres for

each slaves that he brought with him.

The numerical dominance of the American settlers:

1827: By 1827 there were some 12,000 United States citizens living in Texas, while there

were only 7,000 Mexicans.

1835: By 1835 the immigrant population had reached 30,000, while the Mexican population

had barely passed 7,800

The Mexican response to the influx of

Americans 1. Slavery was abolished:

The first important piece of legislation designed to prevent a further weakening of Mexican

control was President Guerrero's emancipation proclamation of 1829. Because slavery as

not important anywhere else in the republic, the measure was clearly directed at Texas.

Although manumission was not immediately enforced, it was hoped that the decree itself

would make Mexico less attractive to colonists from the U.S. South and would thus arrest

immigration.

2. Forbiddance of further immigration:

The colonization law of 1830 explicitly forbade all future immigration into Texas from the

United States and called for the strengthening of Mexican garrisons, the improvement of

economic ties between Texas and the remainder of Mexico by the establishment of a new

coastal trade, and the encouragement of increased Mexican colonization.

Texas Declaration of Independence

• 1835 document declaring independence from Mexico

• Outlines grievances against the Mexican government: lack of free trade, invasion of private property, lack of due process, etc.

• Highly controversial for Mexico

• President Antonio Lopez de Santa Anna declares war

October 2, 1835—The

Battle of Gonzales. The

first battle of the Texas

Revolution begins when

Santa Anna sends a

detachment of Mexican

Calvary to retrieve a

cannon. Texans drive

them back using the

cannon. The battle flag

used by the Texans

features a picture of a

cannon and the written

dare "come and take it."

The Goliad Affair: Mexican forces executed

365 Texan prisoners who had surrendered.

Several weeks after the surrender of the Alamo,

Genaral José Urrea engaged a force of Texans

under the command of Colonel James W. Fannin

at the small town of Goliad. Surrounded and

outnumbered, Fannin surrendered in the belief

that he and his men would be afforded the

recognized rights of prisoners of war. Realizing

that the tenor of the war had been set at the

Alamo, General Urrea wrote to Santa Anna

urging clemency for Fannin and the other

prisoners. Urrea then moved on to another

engagement and left the Texas prisoners in the

charge of Lieutenant Colonel Nicolás de la

Portilla. Santa Anna, however, ordered Nicolás

de la Portilla to execute the prisoners, which he

promptly did despite some moral misgiving. All

365 prisoners were executed.

III. Texas Boundary Dispute

• Asserted the Rio Grande as Texas’ southern boundary

• Treaty of Limits: asserted the boundary at Nueces, Texas as Mexican territory (1831)

• President James K. Polk supports Texas claims to the R.G.
