Yes! Ironically, the existence of the "New World' meant that there was a place for radicals to go to try to establish their utopia when things got difficult at home - for example, the Cromwell family were beginning to settle in N. America when the opportunity arose to, perhaps, achieve what they were after in Britain - but this also meant that the pressure was relieved here, sadly, in the 17th and 18thc, e.g. in the case of 18thc radicals like Paine, who'd go to America or France instead. (Sorry, I'm not as coherent as I'd like to be here - birthday drinks!). In the 1640's in particular the Levellers and Diggers (aka True Levellers) tried to go the whole hog - marxists.org has some of their declarations - including a sort of proto-rights of man. The historian Christopher Hill has written a lot on them, and they are finally getting their due - a permanent exhibition in Putney to commemorate the Putney Debates (there's a theory that Cromwell deliberately engineeered Charles 1's escape from prison to force them to curtail these radical debates and return to war), and the Digger Winstanley's words were used on banners at the various anti-capitalist demonstrations in the last decade. The 'English Jacobins' in the late 18thc, and the Chartists, very much in the Jacobin tradition, in the early 19thc, were violently suppressed. There's also a feeling tha WW1 gave the govt a convenient excuse to pack a lot of young men off to war and slaughter, thus avoiding radicalisaton at home - the Tsar was refused asylum in Britain because this was also believed to be provocative.
On the 20thc - I might blog on my lj at some point my theories on the 1940's and 1980's - I've got a thesis on 1940's/50's cinema, and how 'brideshead revisited' wa used as a propaganda tool inthe early 80's, I need to explore!
