In 1817, Ellis moved to Alabama, settling first in
Huntsville and then in
Tuscumbia, where he practiced law and established a plantation. He was elected a delegate to Alabama's Constitutional Convention in 1818, which created the framework for the state’s admission to the Union. In 1819, he was elected judge of the Fifth Circuit Court, a position that also made him an associate justice of the
Supreme Court of Alabama. Ellis was known for his strict courtroom demeanor, earning a reputation for firm administration but also alienating some members of the bar with his rough manner. In 1829, he co-founded La Grange College in
Franklin County, Alabama, and served on its first board of trustees.
Initial move to Texas Ellis first visited Texas in 1826, attempting to collect a debt from a local colonel. That same year, he participated in an unsuccessful diplomatic mission alongside
James Kerr and
James Cummins to persuade
Haden Edwards to abandon
his rebellion against the Mexican government. In defiance of the
Mexican immigration ban, he established a substantial cotton plantation and gained a reputation for his hospitality and refined estate. Although he was selected as a delegate to the Arkansas Constitutional Convention of 1836, he declined due to ill health. Shortly thereafter, he was elected as one of six delegates from the Pecan Point area to the Texas Constitutional Convention.
President of the Texas Constitutional Convention At the convention that opened on March 1, 1836, at
Washington-on-the-Brazos, Ellis was unanimously elected president. The following day, he signed the Texas Declaration of Independence as presiding officer. While some contemporaries questioned his effectiveness as a moderator, he was widely recognized for his knowledge of parliamentary procedure and his calm, dignified leadership. Most notably, Ellis presided over the convention for the seventeen days required to draft a constitution for the Republic of Texas. == Later life ==
