Polk was the president during the war. • Many Americans supported the war, but not all of them. Abolitionists opposed the war because they were afraid that the southern states would expand slavery into new land. Some slave owners thought the new territories might ban slavery.

3. The Beginning • The United States added Texas as their 28th state. • This caused the US to inherit Texas’s border dispute with Mexico which lead to war. • The war began when Mexico attacked American troops at the border of Texas because of the U.S. annexation of Texas.

Bear Flag Revolt • A small group of American Settlers declared that California was an independent republic. • They created a flag to represent themselves as a new republic. • The revolt caught the attention of John C. Fremont and he quickly declared that he would conquer California without knowing the United States and Mexico were at war.
