The Battle of Naseby (1645)
The Battle of Hastings (1066)
The Norman conquest of England
The Norman Conquest was a cataclysm for the English people. After 1066, ... Castles, until then a rarity, sprang up everywhere. ... these were not defences against a foreign foe, but instruments of internal repression, ... More telling, though, is the political vocabulary introduced under the Normans. Out go witan, folkmoot and folkright. In come fealty and homage, fief and vassal, villein and serf. The progress toward personal liberty, free contract and equal access to the common law was suspended. ...
witan "to know"
folkmoot "a general assembly of the people"
fief, feudal duties
So, when politicians are able to openly criticise at least the outer layer of the established stupidities of to just obey; it gets closer to openly talk about the real core of the terror.
