In late April, one of the world’s strangest laws was quietly revoked. Authorities in Iceland’s Westfjords district, the scenic northwestern corner of the Scandinavian island nation, repealed a 400-year-old decree ordering the death on sight of any Basque person found in the region.

This old grudge stems from a grisly incident in 1615, when misunderstandings and suspicions between locals and a group of shipwrecked whalers from what’s now the northern coast of Spain led to the slaughter of 32 Basques. The decree was ordered by the district’s bloodthirsty magistrate. Of course, newer laws have since been put in place, and no person from the Basque country has been in actual danger for a very long time.

“The decision to do away with the decree was more symbolic than anything else,” Westfjords district commissioner Jonas Gudmundsson told reporters last month. “We have laws, of course, and killing anyone — including Basques — is forbidden these days.”

In a country of Iceland’s small size — it has a population of just over 300,000 people — such seemingly obscure episodes still have a profound resonance. The prominent Icelandic author Sjon wrote of the “slaying of the Spaniards” in his acclaimed 2011 novel From the Mouth of the Whale, depicting the incident as a hideous act of treachery and opportunism carried out against the shipwrecked sailors.

Though remote and sparsely populated, Iceland still found itself at the crossroads of all sorts of global history. The Viking explorers who first reached the New World set sail from its coasts. A decade after the killings of the Basque whalers, raiders from as far away as North Africa ravaged the Icelandic coast, kidnapping hundreds of locals as slaves. The “Turkish abductions” of the 17th century are a defining event in Icelandic national memory and enshrined in the country’s most famous church in the capital, Reykjavik.
