Isaac Johnson's term as Governor began in controversy when Whig Party opponents claimed he had taken an improper oath and was not legally governor.
His administration continued in conflict when he appointed Whigs instead of fellow Democrats to some offices.
Johnson took a strong stand on the issue of the expansion of slavery into new U. S. territories. He denounced illegal the Wilmot Proviso which would have prohibited the sale of slaves in the territories obtained from Mexico after the Mexican War.
In 1849, Johnson moved his office to Baton Rouge--the new seat of state government had been selected by the legislature in 1846.
Johnson became Attorney General after he left the Governors office. He died of a heart attack in a New Orleans hotel in 1853 while running for a seat on the State Supreme Court.
He is buried in West Feliciana Parish.
