To be one of Queen Victoria’s ambassadors in the middle of the 19th century, when British power was at its height, was to be something close to a king—in parts of the world, close to a god. Backed by the full might of the Royal Navy, which ruled unchallenged over the Seven Seas, solitary Englishmen thousands of miles from home could lay down their version of the law to entire nations, and do so with the cool self-confidence that came from knowing that, with a word, they could set in motion perhaps the mightiest war machine that the world had ever seen. (“Tell these ugly bastards,” Captain William Packenham once instructed his quaking interpreter, having stalked, unarmed and unescorted but for a 16-year-old midshipman, into the midst of a village seething with Turkish brigands, “that I am not going to tolerate any more of their bestial habits.”)
Men of this caliber did not expect to be be treated lightly, much less ordered to pay their respects to a pair of naked buttocks belonging to the president of Bolivia’s new mistress. Yet that—according to a tradition that has persisted since at least the early 1870s, and is widely known in South America as the “Black Legend”—was the uncomfortable experience of a British plenipotentiary who encountered the Bolivian caudillo Mariano Melgarejo in 1867. Accounts of the event go on to relate that when the diplomat indignantly refused, he was seized, stripped naked, trussed with ropes and thrust onto a donkey, facing backward. Thus afforded a clear view of the animal’s posterior, Britain’s outraged ambassador was paraded three times around the main square of the capital before being expelled from the country.
