US Presidency
1846

The Congress of Texas on the 19th of December, 1836, passed An act to define the boundaries of the Republic of Texas, in which they declared the Rio Grande from its mouth to its source to be their boundary, and by the said act they extended their civil and political jurisdiction over the country up to that boundary. During a period of more than nine years which intervened between the adoption of her constitution and her annexation as one of the States of our Union Texas asserted and exercised many acts of sovereignty and jurisdiction over the territory and inhabitants west of the Nueces.
