The Texas Declaration of Independence was the formal declaration of independence of the Republic of Texas from Mexico in the Texas Revolution. It was adopted at the Convention of 1836 at Washington-on-the-Brazos on March 2, 1836, and was formally signed the next day after mistakes were noted in the text.

The Centralist Republic of Mexico, or in the anglophone scholarship, the Central Republic, officially the Mexican Republic, was a unitary political regime established in Mexico on 23 October 1835, under a new constitution known as the Siete Leyes after conservatives repealed the federalist Constitution of 1824 and ended the First Mexican Republic. It would ultimately last until 1846, when the Constitution of 1824 was restored at the beginning of the Mexican-American War.
