Final answer:
Northern manufacturers in 1827 called for a protective tariff to safeguard their goods from foreign competition, which led to a bitter regional debate over such tariffs' fairness.
Step-by-step explanation:
In 1827, northern manufacturers demanded a tariff to protect their industries from foreign competition. The type of tariff they were seeking is known as a protective tariff. A protective tariff is designed to shield domestic industries and workers by increasing the cost of imported goods, making them less competitive with local products.
This not only generates revenue for the government but also encourages consumers to buy domestically-produced goods. However, these tariffs often lead to higher prices for consumers and can provoke retaliatory measures from other countries, as was the case with the Southern states' opposition to the Tariff of Abominations in 1828, which they felt unfairly favored Northern interests.
