The Straw Hat Riots of 1922

The Straw Hat Riot of 1922 was a riot that occurred in New York City at the end of summer as a result of unwritten rules in men's fashions at the time, and a tradition of taunting people who had failed to stop wearing straw hats after autumn began. Originating as a series of minor riots, it spread due to men wearing straw hats past the unofficial date that was deemed socially acceptable, September 15. It lasted eight days, leading to many arrests and some injuries.... By the early 20th century, straw boaters were considered acceptable day attire in North American cities at the height of summer even for businessmen, but there was an unwritten rule that one was not supposed to wear a straw hat past September 15 (which was known as "Felt Hat Day").[1] This date was arbitrary; earlier it had been September 1, but it eventually shifted to mid-month. It was socially acceptable for stockbrokers to destroy each other's hats, due to the fact that they were “companions”,[2] but it was not acceptable for total strangers. If any man was seen wearing a straw hat, he was, at minimum, subjecting himself to ridicule, and it was a tradition for youths to knock straw hats off wearers' heads and stomp on them.[3] This tradition became well established, and newspapers of the day would often warn people of the impending approach of the fifteenth, when men would have to switch to felt or silk hats.[4] Hat bashing was only socially acceptable after September 15, but there were multiple occasions leading up to this date where the police had to intervene and stop teenagers.[2] The riot itself began on September 13, 1922, two days before the supposed unspoken date, when a group of youths decided to get an early jump on the tradition.
