1. Texas revolted because the Mexican government canceled Texas autonomy by canceling the validity of the Texas constitution and promoting a more unitarian government. This action, in addition to taking away the state's autonomy, as has already been said, prevented Texas from promoting its own tax collection and having to pay higher taxes to the federal and unitary government that was established in Mexico.
2. The Texas Declaration of Independence was written by George Childress, although he did not get much support for writing that declaration, Childress was an honorable man and committed to relevant political values, however, he was not a Texan by birth, since he was born in Tennessee , which undermined the credibility of his text in relation to the Texan population. However, because he is directly involved in the American revolution, we can consider his accounts of this event to be credible.
3. The document aims to state the reasons that led the Texans to seek independence. As it represents a primary source, since it was written at the time that this historic event was taking place, we can consider that the Texas declaration of independence has high reliability in relation to the proof of why the Texans revolted, mainly because it exposes the reasons for this revolt.
4. The authors may have chosen this position because the United States' declaration of independence was a fantastic, succinct, direct and mainly efficient text, since it got popular support and managed to stimulate the struggle for independence, thus being a great model to be followed.
