How and why did President Polk gain control over Texas?

By falsifying a war, declaring that Mexico was attacking Texas.

Abraham Lincoln, as a senator, created the "spot resolutions" demanding that Polk point to the spot at which Mexico had initiated hostilities, because he knew that that spot was not within the territory of Texas.
