In pursuit of his agenda, Tyler exploited executive prerogatives and manipulated constitutional requirements in ways that violated his professed allegiance to a strict interpretation of the Constitution. He set precedents that his successors in the White House invoked to create an American empire and expand presidential power.
Crapol also highlights Tyler's enduring faith in America's national destiny and his belief that boundless territorial expansion would preserve the Union as a slaveholding republic. When Tyler, a Virginian, opted for secession and the Confederacy in 1861, he was stigmatized as America's "traitor" president for having betrayed the republic he once led. As Crapol demonstrates, Tyler's story anticipates the modern imperial presidency in all its power and grandeur, as well as its darker side.
