<u>Broad Context:</u> The "Big Picture" is that the US is trying to annex the Republic of Texas as part of their states, and that Texas already <em>shared many common traits </em>(why? part) with the US, and should join as a state of their choosing, (which means slave or free) (How? part).
<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.
