Class Warfare

A situation created when society has been deeply stratified between them that has (the lords of the manor) and them that hasn't (the serfs, the labourers and the grimy, grotty soldiers). The peasants get pissed off, the lords get frightened and heads start to roll. All smoothed out about ten or so years ago, if you believe certain politicians.

However, apparently alive and well in modern Britain; see The NIMBYs of Ashtead.
