Which Texas Constitution established the Republic of Texas?

The Texas Constitution that established the Republic of Texas is the one from 1836. This constitution was created following Texas's independence from Mexico, marking the formal establishment of the Republic. It set the framework for the government of Texas as a separate entity, outlining the structure of the executive, legislative, and judicial branches, as well as civil liberties and rights for the citizens of the Republic.

The significance of the 1836 Constitution lies in its role as a foundational document, marking the transition from a territory under foreign rule to an independent nation. This document paved the way for the governance and legal structure that Texans operated under until Texas later joined the United States in 1845.

Although the 1845 constitution is important as it re-established Texas as a state within the United States context, it did not establish the Republic initially. The later constitutions from 1861 and 1869 were also revisions reflecting changes such as the secession from the Union and the post-Civil War era, but these were not the founding documents of the Republic itself.
