In the years before the Civil War which state was most likely to favor higher tariffs?

In the years before the Civil War, the Northern states, particularly Pennsylvania and New York, were most likely to favor higher tariffs. These states had industrial economies that benefited from protective tariffs, which shielded their manufacturers from foreign competition. Conversely, Southern states, reliant on agriculture and exports, typically opposed high tariffs as they increased the cost of imported goods and could provoke retaliatory measures from foreign markets.
