The outbreak of the American Civil War is now more than 150 years past. All the while, the question of what caused the conflict continues to spark disagreement, this despite a longstanding consensus among specialists that slavery – a cultural, political, ideological, and economic institution that permeated (and divided) mid-19th-century American society – was the primary cause of the war. One of the most egregious of the so-called Lost Cause narratives instead suggests that it was not slavery, but a protective tariff that sparked the Civil War.
On 2 March 1861, the Morrill Tariff was signed into law by outgoing Democratic President James Buchanan to protect northern infant industries. A pernicious lie quickly formed around the tariff’s passage, a lie suggesting that somehow this tariff had caused the US Civil War. By ignoring slavery’s central role in precipitating secession and Civil War, this tariff myth has survived in the United States for more than a century and a half – and needs to be debunked once and for all.
In trying to make their case but lacking adequate evidence for the 1860-61 period, “Lost Cause” advocates instead commonly hark back to the previously important role that another protective tariff had played in the 1832 Nullification Crisis. They then (mistakenly) assume the political scenario to have been the same three decades later – that southern secession from 1860-61 was but a replay of the divisive tariff politics of some thirty years before. From this faulty leap of logic, the argument then follows that the Republican Party’s legislative efforts on behalf of the Morrill Tariff from 1860 until its March 1861 passage became the primary reason for southern secession – and thus for causing the Civil War.
