The most obvious difference is that the Glorious Revolution represented the affirmation or strengthening, but also a kind of adjustment, of an existing constitutional system, while the French Revolution overthrew an existing system of government.
The English Constitution has, throughout its history, been an evolving entity. Parliamentary democracy has been achieved gradually over a period of centuries, with key events that altered the balance of power between the King (or Queen) and the legislature, the representative of the people. In 1688, James II was expelled because he was perceived as acting against English liberty. William of Orange was brought in to replace him, but this did not mean the monarchy was abolished. The system of government, that of a constitutional monarchy, was preserved and still exists today—over 300 years later.
The French Revolution, on the other hand, abolished the monarchy (though this was not explicitly the intent from the start) . At first, the plan of those who initiated the revolutionary process was to preserve the monarchical system but to introduce democracy through a constitution, which Louis XVI was basically forced to accept. This in itself was quite different from what had occurred in England 100 years earlier. But events spun out of control. The king was distrusted at least from the time in June of 1791 when he had tried to escape from France. In 1792, the monarchy was abolished and the king and queen executed. This completed the overthrow of the system of government France had for centuries.
The events in France affected all of Europe. The other European leaders feared that similar revolutions would be initiated in their countries. Austria and Prussia declared war on France in 1792, initiating a period of 23 years of almost continuous war. No such outcome had occurred in response to the English revolution in 1688, which was essentially an internal governmental adjustment that did not threaten the other European monarchies. As Edmund Burke wrote in his Reflections on the Revolution in France, the events beginning in July of 1789 were like nothing that had previously occurred in Europe. These events changed not just Europe, but the entire world.
