The Convention of 1836 was the meeting of elected delegates in Washington-on-the-Brazos, Texas in March 1836. The Texas Revolution had begun five months previously, and the interim government, known as the Consultation, had wavered over whether to declare independence from Mexico or pledge to uphold the repudiated Mexican Constitution of 1824. Unlike those of previous Texas councils, delegates to the Convention of 1836 were younger, more recent arrivals to Texas, and more adamant on the question of independence. As delegates prepared to convene, Mexican President Antonio Lopez de Santa Anna led a large army into Texas to quell the revolt; the vanguard of this army arrived at San Antonio de Bexar on February 23.

The Convention was called to order on March 1, and the following day adopted the Texas Declaration of Independence, written by George Childress. Delegates elected an interim government, led by President David G. Burnet and developed a Texas Constitution, which they based primarily on the Constitution of the United States. On March 6 they received a missive from the Texan soldiers besieged at the Alamo, and delegate and commander-in-chief Sam Houston narrowly persuaded the men to continue their work on the constitution rather than rush to aid the soldiers. After the Alamo fell, Santa Anna's army marched towards Washington-on-the-Brazos, prompting the new government to flee.
