The Texas Declaration of Independence
(March 2, 1836)

The Texas Declaration of Independence was produced, literally, overnight. Its urgency was paramount, because while it was being prepared, the Alamo in San Antonio was under seige by Santa Anna's army of Mexico.
Immediately upon the assemblage of the Convention of 1836 on March 1, a committee of five of its delegates were appointed to draft the document. The committee, consisting of George C. Childress, Edward Conrad, James Gaines, Bailey Hardeman, and Collin McKinney, prepared the declaration in record time. It was briefly reviewed, then adopted by the delegates of the convention the following day.

As seen from the transcription below, the document parallels somewhat that of the United States, signed almost sixty years earlier. It contains statements on the function and responsibility of government, followed by a list of grievances. Finally, it concludes by declaring Texas a free and independent republic.
