Why was Governor Sam Houston against Texas secession? I need it answered

Yes, Governor Sam Houston was against the secession of Texas from the Union.

Explanation:

On the day that Texas secession was decided in Austin, Sam Houston, who was then the 67-year-old governor of Texas, had managed to win out over the strong secessionist sentiment in the state government and among other influential Texans for some time. Sam Houston has also twice been president of the Republic of Texas when it was independent from both Mexico and the United States. Houston had valiantly fought for Texan independence from Mexico and he was the figure who had negotiated the inclusion of the Republic into the Union. He had dedicated a large part of his career to assuring that Texas was a part of the United States so he was fervent on keeping Texas a part of the Union.
