War of Jenkins' Ear

The War of Jenkins' Ear serves in Federalist No. 6 as a warning that commercial disputes can escalate into national conflict and unsettle alliances far beyond their point of origin. The account traces the war to British merchants’ illicit trade with Spanish America, the Spanish response against British subjects, and complaints that stirred British public and parliamentary pressure for war.

Commercial Causes and Retaliation

The immediate background was a contest over trade. British merchants attempted to pursue illicit commerce with the Spanish mainland. The account condemns those practices, while also judging Spain’s treatment of British subjects unjustifiable: Spanish retaliation exceeded what could be considered fair and was described as cruel. Some English captives taken on the Spanish coast were sent to work in the mines of Potosi.

The account emphasizes how retaliation blurred distinctions between those responsible for the illicit trade and those who were not. As resentment grew, innocent people were punished alongside the guilty. The conflict thus arose not from a single grievance in isolation, but from an escalating sequence in which commercial violations provoked excessive reprisals and indiscriminate punishment.

From Complaints to War

Complaints from merchants spread beyond the individuals directly involved and kindled strong feeling throughout Britain. The agitation reached the House of Commons and passed from that body to the ministry. Letters of reprisal were granted, and war followed. The sequence makes public pressure part of the causal account: commercial grievances became national claims, entered parliamentary debate, and helped produce an official resort to war.

Consequences and Political Significance

The war’s consequences reached beyond Britain and Spain. It overturned the alliances that had been formed only twenty years earlier with confident expectations of substantial benefit. In the argument of Federalist No. 6, this reversal demonstrates how commercial competition and the desire to gain or defend trade can disturb political arrangements and make the consequences of conflict difficult to contain.

The episode forms part of a broader warning against assuming that separate political communities will naturally remain peaceful. The essay places this war among examples of hostilities arising from commerce, resentment, and political pressure, using their history to challenge expectations of enduring harmony among states left in separation. Its significance lies both in the chain linking illicit trade, retaliation, popular agitation, and war, and in the way the resulting conflict damaged an alliance beyond the two countries directly involved.
