Final answer:
Andrew Jackson's tone in his message to Congress is one of nationalistic pride, highlighting America's transformation from a wilderness to a flourishing republic.
Step-by-step explanation:
The tone Andrew Jackson conveys in his message to Congress is one of triumph and nationalistic pride as he contrasts the transformation of land once covered with forests and inhabited by a few thousand Native Americans to an extensive republic bustling with cities, towns, and prosperous farms.
He speaks with a sense of accomplishment about the growth of a population enjoying the blessings of liberty, civilization, and religion. Jackson's rhetoric was characterized by his support for states' rights and the will of the majority, seeking to refocus federal government actions to benefit the common farmers and laborers.
In his democratic vision, Jackson saw progress in the replacement of the earlier landscape and populations with a new society representative of American greatness. His stance was also indicative of the era's prevailing view that Native Americans were impediments to progress and had no place in the White republic, a sentiment reflected in policies like the Indian Removal Act of 1830. It's clear that Jackson's tone intended to reinforce the belief in American exceptionalism and the destiny of the United States to expand and prosper.
