1795: The Republican Attack, by James Gillray.
Note that the 'mob' only wants 'peace and bread', and that Britannia is crushed under the carriage. This really happened, by the way, and led to even more repressive laws than were already in existence. I'm sure that won't be the case now… ha ha ha.
I'm starting to think that I can understand and even predict current political developments by going back to the 18th Century. After all, the landed aristocracy are in charge, millionaires run the place, the state is being abolished, we're at war (though not with France, for a change) and satire is the only weapon we have. Squire Turniphead Cameron certainly isn't listening.
