Why was the Glorious Revolution glorious?

Answer 1

It was only glorious for people who like religious persecution and bigotry. James II and VII proclaimed religious toleration and tried to protect all religious minorities. He was overthrown by religious bigots, who replaced him with the dictator named William of Orange. The whole thing was illegal, which is why the Jacobite successors: James VIII and Charles III were the only true legitimate monarchs.

Answer 2

I believe that its referred to as the Glorious Revolution for a number of reasons, but the primary reason being that it was a "bloodless" revolution. King James abdicated the thrown "willingly" and William of Orange ascended without a military coup. Typically power vacuums led to incredibly bloody infighting among rival factions vying for the thrown, or outright Civil War, so for one of Europe's strongest powers' monarchs to abdicate without anyone dying was quite a feat.

Many historians believe that this event was also the beginning of Europe's first Parliamentarian Democracy - Parliament had been battling with the King for years to obtain more than just an "advisory" role, and after James's rule, Parliament for the first time put a limit on the power of the Thrown, and took the first steps toward setting up the more Democratic government that the British enjoy today.

Finally, one more reason of less importance may be that James was a Catholic, and with his removal Catholicism was finally banished from the state. This ended an ongoing political battle that had been raging in Britain since Henry VIII's rule.
