What major event prompted the creation of the first bucket brigade?

The creation of the first bucket brigade is historically attributed to the need for an organized response to fires, particularly in densely populated urban areas. The major event that notably highlighted the danger and urgency of fire control was the series of devastating conflagrations that occurred in ancient Rome. These fires often spread rapidly through the city, which was built with closely packed buildings and highly flammable materials.

In response to these catastrophic fires, Romans recognized the necessity for a systematic approach to firefighting, leading to the establishment of the bucket brigade. This method involved passing buckets of water from person to person to combat flames more efficiently than ad-hoc efforts. Therefore, the significant threat posed by these conflagrations in Rome directly contributed to the development of organized firefighting tactics, making this the most appropriate context for the birth of the bucket brigade.
