In July 64 CE, a fire erupted in Rome's merchant quarter and spread throughout the city's densely populated districts. The blaze burned for six days and destroyed ten of Rome's fourteen districts, leaving much of the population homeless. Emperor Nero was in Antium when the fire began but returned to implement relief measures. Rumors circulated that Nero had orchestrated the disaster to clear land for his planned Domus Aurea. Nero blamed the Christian community for the fire, initiating the first Roman persecution of Christians and marking a shift in Roman-Christian relations.
