What do you think the overall reaction in Britain was to the French Revolution? Do you thing it changed after the regicide and the ensuing terror?
As far as I know Pitt was somewhat indifferent, he had the view that the French could do what they wanted in France, it was only when the revolutionaries tried to force their ideals on their neighbors that the British reacted.
I'd have assumed that it would have terrified Britain, for fears that it would spark revolutions in British colonies, such as the US or Ireland.
They love their monarchy a little bit too much in Britain
And about the French revolution, I think the main aim of the british ruling class was to avoid a unique continental power in Europe, like the French republic.
Initially the British government was quite favourable to the revolution, as were the Opposition and many interested parties outside of Parliament. There was the famous pamphlet war between Edmund Burke, Thomas Paine and Mary Wollstonecraft (among others), and Burke was seen largely as an alarmist minority. But he was proved right, ultimately.
Hostility to the revolution grew after the new French legislature began attacking church and property rights throughout France. The legislature came up with some truly crazy, crank ideas based on metrical assumptions of human nature rather than application based on past experiences. Then the King was executed, the monarchy abolished, and the Terror ensued. Once that happened, British opinion to the revolution turned resolutely sour.
There's some thought that if Napoleon had satisfied himself with the borders of France and refrained from his habit of using war as a first resort, the British might have grudgingly acknowledged him as France's rightful sovereign. But as he was determined to dominated Europe, and it had long remained Britain's policy to prevent one power doing that, Britain could never accept Napoleon on the throne.
Britain was actually terrified and shocked at the french revolution like most of Europe.
They harbored many french aristocrats who where trying to flee and supported a french royal family who they had been war with previously. Britain actively supported Europe even going as far as using it's army during the french revolutionary wars. Britain partially did not want a repeat of the english civil war and also realised that both sides in our previous civil war would not have been safe in a new revolution.
The British parliament's mind set was so altered they where pretty much terrified about a british revolution until the mid 1800's.
You have to remember the whole anti-monarchy feeling during the french revolution was nothing to do with notions of democracy, more the massive gap between the rich aristocracy and average people. Up until the 20th century most british MP's were still upper class and many relied on pointing out how the middle classes had buggered france up following the revolution to support the view the common people should not have the vote until the 1918/28.
