Based on the options you gave, the Revolution you're talking about is the French Revolution. A revolution such as this was a Western phenomenon because it was not common in Eastern countries to rise against their monarchies because of the traditions, the religious aspects, and the way how the Eastern societies were arranged. On the other hand, the French Revolution, and the way how their promoters made it happen created a kind of pattern that spread across Europe, and especially in the Americas (the Central and South America, to be precise), and it's the root of the modern revolutions.
