On June 1, 1868, a constitutional convention convened in Austin. 78 of the 90 convention delegates answered the first day’s roll call. In an early indication of the political dynamics that would be at play between multiple factions of the dominant Republican party, General (and future Texas Governor) Edmund Jackson Davis was elected president of the convention over Texas Supreme Court Justice Colbert Caldwell. As president of the convention, General Davis supported expanded rights for blacks, as well as the “ab initio” theory that all post-secession laws enacted in Texas were null and void. These would prove to be major issues in the deliberations of the convention, whose incomplete work ultimately became the basis of the 1869 Texas constitution.
