On 17 August 1979, Monty Python’s Life of Brian premiered in New York, sparking protests and bans across multiple countries despite the film’s careful distinction between satire and blasphemy. George Harrison mortgaged his house to fund it, Sweden marketed it as ‘the film Norway banned’, and the resulting cultural conversation revealed more about human groupthink than any sermon. Meanwhile, in 1498, Cesare Borgia accomplished the impossible by resigning his cardinalate in the morning and becoming Duke of Valentinois by evening, the first person in Church history to hand back the red hat. In 2005, Bangladesh experienced over 500 coordinated bomb explosions across 63 districts in 30 minutes, a logistical demonstration of reach that shook an entire nation. And in 1982, PolyGram demonstrated the first commercial audio compact discs: Chopin waltzes and ABBA’s final album, launching the digital music era that would render its own format obsolete within three decades. Clara Vale examines four moments that demonstrate humanity’s talent for banning the wrong things, breaking the unbreakable rules, and building technologies we later abandon.
