“His grandfather was the tenth President of the united states”
And one of only four Whig Presidents. Tyler was also elected to the Confederate States Congress but died before taking his seat.
President Tyler was chosen to head a peace convention that met in Washington in February 1861 for the purpose of heading off civil war.
Only the Deep South states had seceded at the time; Virginia, North Carolina, Tennessee and Arkansas were still in the union. Those four wouldn’t leave until Lincoln called up an army to force the Deep South states back into the union.
He wasn’t a Whig President for long. The Whigs kicked him out of the party 5 months after he took office.
