I suspect you mean 1836, not 1863, since the last President of Texas left office in February of 1846, after Texas became a state of the United States. David G. Burnet was elected Interim President in 1836 by the convention that assembled to issue Texas' Declaration of Independence from Mexico. Later that year Sam Houston was elected by popular vote to be the first President of Texas. He was also the third President of Texas (the Texas Constitution did not have term limits, but it did not allow anyone to serve consecutive, or back to back, terms).
