The song lyrics are basically talking about history and how so many kings ruled during time. During times in Europe, when kings still existed, sometimes they did not just dethrone them etc. The lyrics- "Revolutionaries Wait
For my head on a silver plate"
That means they are just waiting for the next king to be executed. This song is also told through the eyes of a ruler who was removed of his position as king. This is a great song that also has history placed into it.
