<u>Other Context:<em> </em></u><em> </em>The adding of Texas into the US (eventually as a slave state) offsetted the balance between the slaves and free states, and so California (gained after the Mexican-American War) was turned into a free state. Texas was the cause of the Texas Revolution & later on the (already named) Mexican-American War. The adding of Texas, and later the Gadsen Purchase, help create today's US southern border that is shared with Mexico.
