Clay's American System (1820's)
1 Jan 1820
Causes: The new technology of the Market Revolution boosted manufacturing, trade, and agriculture so the US Government wanted to encourage manufacturing and trade in the US.
People: Henry Clay
Effects: Import tariffs, internal improvements (roads, canals), and a National Bank helped the US economy develop. The South disliked the American System because tariffs hurt them and the Bank and roads only benefitted the North (and West).
