Can you explain me this song please?

Lady Gaga__song about the french revolution

Inequality the relics of feudalism1
Revolution in France
Oh, the Three Estates2 ensured nobles favoritism
Revolution in France
La la liberte
Egalite
Fraternite
A revolution

La la liberte
Egalite
Fraternite
A revolution

Don’t want no taxes, I’m paying too much
Let them eat cake, we had a banquet for lunch
I need my bread bread bread bread
Off with her head

It went from 8 sous4 to 12 in a year
Exactly what impoverished peasants had feared
The royals jeered
Ha ha ha there’s more for us

There was a famine
The peasants wouldn’t pay
Bad malnutrition and tooth decay
It went from famine to Napoleon’s War
You and me let’s start a revolution
We will not take this poverty anymore
You and me, let’s start a revolution

On a tennis court we swore to a constitution
Revolution in France
On July 14, we stormed the Bastille; we showed them
Revolution in France

La la liberte
Egalite
Fraternite
French revolution

The month of August 1789, no feudalism, Declaration of Rights
August Decree
Swept away the two estates
Women of Paris march down to Versailles4
Carrying weapons, The French king they defied
You’ll give us bread
Bread! Bread or we’ll stab you dead!
A new constitution with a limited monarchy
It was a bad time for France

We took on Austria, a war in the spring
Europe frightened by our revolution
We will not take it, Louis XVI must die,
Tension heightened by our revolution
Radical political mobs unite to start a
Revolution in France
Breech-less sans-culottes of the Paris Commune demanded
Revolution in France

La la liberte
Egalite
Fraternite
French revolution

La la liberte
Egalite
Fraternite
French revolution

Walk walk, scaffold baby, guillotine5 was going crazy
Take heads of kings and ladies, Europe armed for the invading
Walk walk, scaffold baby, guillotine was going crazy

Robspierre6, Reign of Terror did it for the Public Safety
Don’t want no church, Catholicism’s dead
No room for God, worship reason instead

Good ol’ Notre Dame became a “temple of reason”
Revolution in France
A new calendar with months named for times and seasons
Revolution in France
A Revolution I want your loyalty or I’ll get my revenge
I take you out until your rebellion ends

The Terror ended and with Robspierre gone
Was this the ending of the revolution?
Five members of the New Directory ruled,
Could it be a permanent solution?

Directory and legislature filled with with corruption
Revolution in France
Monarchists and wars would cause even more disruption
Revolution in France

Oooh oooh oooh la la
Coup Coup Coup detat
Oooh oooh oooh la la
Napoleon’s here!
