French Revolution, in Coldplay's song?

Viva la vida is probably the most known Coldplay's song ever. Everyone knows the lyrics but, who does really understand its meaning?

Here are the lyrics:

I used to rule the world

Seas would rise when I gave the word

Now in the morning I sleep alone

Sweep the streets I used to own

I used to roll the dice

Feel the fear in my enemy's eyes

Listen as the crowd would sing

"Now the old king is dead! Long live the king!"

One minute I held the key

Next the walls were closed on me

And I discovered that my castles stand

Upon pillars of salt and pillars of sand

I hear Jerusalem bells are ringing

Roman Cavalry choirs are singing

Be my mirror, my sword and shield

My missionaries in a foreign field

For some reason I can't explain

Once you go there was never

Never an honest word

And that was when I ruled the world

It was the wicked and wild wind

Blew down the doors to let me in

Shattered windows and the sound of drums

People couldn't believe what I'd become

Revolutionaries wait

For my head on a silver plate

Just a puppet on a lonely string

Oh who would ever want to be king?

I hear Jerusalem bells are ringing

Roman Cavalry choirs are singing

Be my mirror, my sword and shield

My missionaries in a foreign field

For some reason I can't explain

I know Saint Peter won't call my name

Never an honest word

But that was when I ruled the world

I hear Jerusalem bells are ringing

Roman Cavalry choirs are singing

Be my mirror, my sword and shield

My missionaries in a foreign field

Woahahahah. woah ohhhhh woah ohhh oh,

For some reason I can't explain

I know Saint Peter won't call my name

Never an honest word

But that was when I ruled the world

Now let's go back to the meaning part. 

This song is sung in first person, as like someone is telling his own story. Is he the French king Louis XVI? we are not sure. Usually the singers tell us about their feelings, but in this song, a man is explaining how he wasn't the perfect king and how people hated him.

Louis XVI was King of France between 1774-1791. He tried to do some ''reforms'' in France and that caused that people were not happy with them, so they started a revolution, THE FRENCH REVOLUTION.

This song talks about how the king (Louis XVI?) lost his power and the citizens rised up against the government, so they wanted to behead him. Or the meaning could be a reflexion about Power and the lost of Power by a man?.

Let's see this on some of the lyrics:

‘’I used to roll the dice’’ - Perhaps this means  that he decided about the destiny of people.

‘’Blew down the doors to let me in’’ - This explains how he used violence to get what he wanted. 

‘’One minute I held the key, next the doors were closed on me‘’ - Everything happened so fast.

‘’And I discovered that my castles stand, upon pillars of salt, pillars of sand‘’ - The castles mean his power, so if they stood upon pillars of salt and sand, that means that they were very weak.

‘’Revolutionaries wait for my head on a silver plate‘’ - This means, as we said before, that people wanted to behead him.

‘‘I know St Peter won’t call my name’’ - St Peter is the one who opens the doors in heaven for christians, so this refers that heaven's doors won't be opened for him.

There are also many references to the Bible: Jerusalem bells, St Peter, 'my head in a silver plate', maybe St. John the Baptist's head?. Anyway whatever the meaning is, enjoy the song!
