The French Revolution was influenced by an unfair tax system, This rural majority lived exclusively off the land.The nobility opposed the king's decision. By a clever game of persuasion, they even rallied part of the third estates at their side to denounce the power of the King. This marked the first stage of the revolution.The wealthy and powerful parliamentarians of Grenoble decided to protest by openly refusing this decision.From now on, the victorious parliamentarians decided not to pay taxes to the King anymore and asked representatives of all the other regions of France to do the same.
Then they were struggling with hegemony and Empire outstrips the fiscal resources of the state.Also conflict between the Monarchy and the nobility over the “reform” of the tax system led to paralysis and bankruptcy. Then when the government's monopoly of power is effectively challenged by some groups who no longer recognize its legitimate authority, no longer grant it loyalty, and no longer obey its commands.Also The Third Estate’s Oath of the Tennis Court in June 1789 and its claim of representing the sovereignty of the nation creates a revolutionary situation in France.the fragmentation of an existing polity into two or more blocs, each of which exercises control over some part of the government and lays claim to its exclusive control over the government.
Another reason why is because of the Constitutional Monarch overthrow.After the establishment of the Republic, the level of violence grew as the Republican regime sought to repress counter-revolutionary movements in France (Federalist revolts and the Vendée uprising) while struggling at the same time to prevent defeat in war by the combined forces of Austria, Prussia, and Britain.The so-called reign of Terror was instituted to quash both internal and foreign forces of counter revolution.But once these internal and foreign threats were under control in the spring of 1794, Terror continued at the direction of the Committee of Public Safety, the most famous member of which was Maximiliean Robespierre. This last period of Terror was aimed at eliminating political rivals of Robespierre and the Committee, which included Danton.The excesses that resulted led to the overthrow of Robespierre and the Committee on the 9th of Thermidor, Year II (July 27 1994).
