London Riot Re-enactment Society

The London Riot Re-enactment Society will stage re-enactments of noted riots from London's history, with some attempt at historical accuracy. You are no doubt aware of the widespread popularity of historical re-enactment societies, you may also be aware of moves to re-enact more recent events in history. The London Riot Re-enactment Society was inspired by the idea that we can re-enact not the distant past, but events that we remember and may actually have taken part in. We have chosen define our re-enactment society not by choosing a period of time, but by choosing a theme. We will tap London's rich history of rioting, and make these riots live again, in our re-enactments.

If you read a bit about the Gordon Riots or Wat Tyler's peasant revolt you will see that the re-enactment of these riots will take vast numbers, and a lot of planning or luck, so we may start with a smaller, more recent riot, such as the Poll Tax riot. But don't worry, the numbers will grow, so far 100% of Londoners who have heard about the LRRS have expressed an interest in joining.
