We did. We had a series of brutal civil wars that began in the 1640s and culminated in 1688. At the end, we established the supremacy of Parliament. We even cut off the King's head (much to the horror of French and Spanish conservatives). In the 18th-century, Britain was admired by French writers and revolutionaries. One of the classics of French literature is a book by Voltaire praising Britain's political system. In fact, Britain's civil wars inspired both the American and French revolutions.
I wouldn't talk too casually about revolution, though. If the 20th-century has one lesson, it's the danger of big ideas. People get some idealistic vision in their head, then they start a revolution in the hopes of achieving it. But the result is usually chaos. After that, the psychopaths come out of the woodwork. Psychopaths like Stalin thrive under those conditions, and when the dust settles, they've usually gained control. That jabbering, greasy egomaniac Russell Brand even published a book called 'Revolution'. I wonder what he'd think if he got his wish, and there really was a sudden, radical transformation of society? In the 19th-century, a German philosopher, inspired by Hegel, came up with a series of revolutionary ideas. In the 20th-century, various idealists tried to impose those ideas on society, and 100 million people died.
If everyone was kind and gentle and civilised, then you could try radically reforming society. You could shake things up and try out different systems until something worked. But they're not. Some people are intelligent and reasonable and civilised. Others are ignorant, violent, amoral, irrational and totally selfish. Civilisation is a fragile thing. It doesn't come naturally to us. We've all known people whose violence and aggression can only just be contained. And that's in a time of peace and prosperity!
