Protective tariffs were a key element of the American System.

Explanation:

The American system was a protectionist economic strategy adopted in the United States after the Anglo-American War of 1812.

The strategy was based on the imposition of heavy tariffs to finance the construction of infrastructures, the development of a central bank that encouraged the company and the strengthening of the internal currency. The tariffs would also have allowed the US to effectively counteract the dumping actions carried out mainly by the British Empire.

In large part, the provision was based on the thought of the American School of Alexander Hamilton.
