So what if Texas conquered the contiguous US? The POD is March 2 1836, the day that Texas became independent. I would imagine that after Texan independence, Texas would expand westward towards the Oregon territory, use Mexicans as slaves along with African slaves, and due to Mexican slavery, there would be no Mexican American War. Texas, after it has conquered the Oregon territory would go eastward towards Ohio and Missouri and continue going eastward until the 13 colonies were conquered. There would be no Civil war and thus slavery would continue until today. This would easily lead to Texas expanding to the entirety of Mexico.
But would this happen if Texas conquers the contiguous US?
