Tariff
A tariff is called an optimal tariff if it's set to maximize the welfare of the country imposing the tariff. It is a tariff derived by the intersection between the "trade indifference curve" of that country and the offer curve of another country. In this case, the welfare of the other country grows worse simultaneously, thus the policy is a kind of "beggar thy neighbor policy". If the offer curve of the other country is a line through the origin point, the original country is in the "condition of a small country", so any tariff worsens the welfare of the original country.
History of taxation in the United States
Tariffs contributed to sectionalism between the North and the South. The Tariff of 1824 increased tariffs in order to protect American industry in the face of cheaper imported commodities such as iron products, wool and cotton textiles, and agricultural goods from England. This tariff was the first in which the sectional interests of the North and the South truly came into conflict because the South advocated lower tariffs in order to take advantage of tariff reciprocity from England and other countries that purchased raw agricultural materials from the South.
