If this is about the French revolution then: ·         
When King Louis XVI ascended the throne, he was met with an empty treasury.  Years of war had depleted the treasury. Loans were taken from money lenders who then began to charge high interest amounts on loans. Unable to pay this, the government increased the taxes. ·        
 → French society, during that time was divided into estates: 
 1st estate-> Clergy
2nd estate-> Nobility
3rd estate-> ·    
≡ Businessmen, merchants, lawyers ·  
 Cooks, servants, etc ·
≡ Landless labour, peasants, etc   ·     
  Taxes were paid by the 3rd estate. There were many taxes such as tailles ( paid directly to state ) and tithes ( paid to church which compromised of 1/10th of agricultural produce ), along with many indirect taxes such as salt tax and tobacco tax. ·     
   On 14th July 1789, the king ordered troops to move into the city of Paris. An agitated crowd of around 8000 people, broke into government buildings hoping to find arms. They finally stormed into Bastille, a fortress-prison, that was hated by all as it stood for the despotic power of the king and freed the 7 prisoners. ·   
 →   Fragments of the prison were sold as souvenirs to those who wanted to keep it a part to represent the start of the downfall of the monarchy.
