Final answer:
Henry Clay's American System included a national bank, protective tariff, and funding for internal improvements, with support differing among regional interests and divisions between states favoring a strong central government and those advocating states' rights.
Step-by-step explanation:
The parts of Henry Clay's American System included a national bank to stabilize the currency, a protective tariff to safeguard American industries and generate revenue, and federal funding for internal improvements like roads and canals to enhance transportation.
These parts were designed to work together to strengthen the nation's economy. The national bank was meant to provide a stable currency and control over credit, the tariff aimed to protect burgeoning American manufacturing and reduce dependence on foreign trade, and the internal improvements were intended to facilitate the movement of goods and materials across the nation.
Clay's American System was particularly supported by those with nationalist views who believed in a strong central government. The Northeastern manufacturing states heavily favored the protective tariff because it benefitted their economy.
The Western states supported internal improvements that would increase access to markets. Conversely, Southern states were often opposed to the tariffs as they relied on foreign trade for their agricultural products and saw tariffs as detrimental to their economy. As Secretary of State under President John Quincy Adams, Clay championed the American System, which Adams also supported, resulting in notable legislation during his administration.
