4 The Journey West  President Polk (1845-1849)  Manifest Destiny: belief that it was our God-given right to expand to the Pacific Ocean.  U.S. settlers moved to Texas while it was still a province of Mexico.  Refusing to abide by Mexican law, the new settlers started a rebellion.

5 Spanish Texas  The Spanish had been in the Americas since Columbus in 1492.  Spain owned a large part of North America, including Texas.

6 Tejanos  In 1821, only about 4,000 Tejanos lived in Texas.  Tejanos are people of Spanish heritage who consider Texas their home.  The Spanish government tried to attract Spanish setters to Texas, but very few came.

7 Moses Austin  An American, Moses Austin was given permission by the Spanish government to start a colony in Texas.  All the Americans had to do was follow Spanish laws.  Moses died in 1821, so his son Stephen tried to start the colony.

8 In 1821, Mexico won independence from Spain

9 Texas Grows  The success of Austin’s colony attracted more land speculators and settlers to Texas from the United States.  Some were looking for a new life, some were escaping from the law, and others were looking for a chance to grow rich.  By 1830, the population had swelled to about 30,000,with Americans outnumbering the Tejanos six to one.

10 Rising Tensions in Texas  In 1829, the Mexican government outlawed slavery.  The settlers wanted to keep their slaves so they could grow cotton.  The Americans also didn’t want to learn Spanish or follow Mexican laws.  Very few settlers had converted to Catholicism.

11 Rising Tensions In Texas  In 1829, the Mexican government closed the state to further American immigration.  Texans had to start paying taxes for the first time.  Mexican president, General Antonio Lopez de Santa Anna sent more Mexican troops to Texas.  Texans began talk of breaking away from Mexico.  When Stephen Austin was jailed, the Texans did revolt.  Santa Anna led 6,000 troops to Texas to put down the revolt.

12 The Alamo  The first battle between the Texans and Mexicans took place at on old mission that was used as a fort.  It was called the Alamo.

13 The Fight for the Alamo  There were only 183 Texans guarding the Alamo.  The Mexican army had 1,800 men.  The Texans held the Alamo for twelve days.  On the thirteenth day, Santa Anna ordered his men to storm the fortress.  When it was over, all but five Texans were dead. The men not killed in the battle were executed by Santa Anna.  Texans were shocked by the slaughter at the Alamo and vowed to fight for their freedom.

14 Lone Star Republic  In 1836, Texas declared itself The Lone Star Republic.  Sam Houston was elected president.  Some Americans wanted Texas to be part of the U.S.  Some people were afraid of Texas becoming a slave state, others of war with Mexico.  Both would eventually happen.
