Territorial disputes between the United States and Mexico began in 1803, when the U.S. claimed Texas as part of the Louisiana Purchase.  The idea of Manifest Destiny and of gaining Mexican territory had strong popular support.  President John Tyler wanted to bring Texas into the Union.  Texas, however, was certain to be a slave state.

6 Antislavery leaders in Congress opposed the annexation of Texas.  Moreover, Mexico still did not recognize Texas’s independence. (pages 306–307) The Lingering Question of Texas (cont.)

7 Many Northerners thought that annexation was a pro-slavery plot.  James K. Polk, a former Congressman and governor of Tennessee, was the Democratic candidate in the 1844 election.  He promised to annex Texas and the Oregon territory and buy California from Mexico.  He won the election.

17 Dangers on the Western Trails Many people who migrated west during the mid-1800s feared attacks by Native Americans. It was certainly a dangerous journey. From 1835 to 1855, more than 10,000 people died while traveling the Oregon Trail. Most people, however, died because of firearm accidents or from diseases such as cholera or smallpox. Less than 4 percent of the deaths on the trail were actually due to Native American attacks. Ft. Vancouver, a British outpost established by the Hudson Bay Company, was often the final stop on the trail before emigrants reached Oregon City. Located on the northern bank of the Columbia River, Ft. Vancouver was a thriving community. John McLoughlin who, despite orders to discourage American emigrants, was known for his hospitality, welcomed tired, hungry, and often barefoot travelers.

18 If the voters in New York who cast ballots for James Birney, the Liberty Party presidential candidate in 1844, had voted for the Whig candidate, Henry Clay would have been the 11 th president. With New York’s 36 votes, Clay would have won the Electoral College vote 141 to 134.

19 Albert Gallatin served as the secretary of the Treasury from 1801 to 1814. He was instrumental in negotiating the end of the War of 1812.

20 Flag’s Origins When California settlers declared their independence from Mexico, they raised a flag with a white background, a single star, a red bar, and a grizzly bear. The bear flag officially became the state flag in 1911.
