National Assembly was formed because Louis XVI was doing injustice with people of third estate , as he wants to increase taxes. He made a policy that one estate will have one vote so that the demand of third estate could not be considered . People of third estate left the meeting. This was the immediate cause of the outbreak of revolution in France. When Louis XVI signed the contract that he accepts the constitution, France became constitutional monarchy. The government thus formed was named as national assembly.

The National Assembly was formed during the French Revolution in 1789. There were many reasons behind the formation of the National Assembly, and some of them are discussed below.

Background:

Before the formation of the National Assembly, France was governed by an absolute monarchy. The king was the supreme authority, and the people had no say in the government. The French society was divided into three estates, and the first two estates had many privileges, while the third estate had to bear the burden of taxes and had no political power.

Reasons for the formation of the National Assembly:

1. Economic Crisis:
France was facing an economic crisis, and the government was bankrupt. The government's expenses were increasing, and the treasury was empty. The king had to raise taxes to meet the expenses, but the burden always fell on the third estate. The third estate was tired of the unfair taxation system, and they demanded representation in the government.

2. Political Crisis:
The political system of France was outdated and corrupt. The king had absolute power, and the nobility and the clergy had many privileges. The third estate demanded political power and representation in the government.

3. Estates-General:
The king called for an Estates-General meeting in 1789 to address the economic crisis. The Estates-General was a meeting of representatives from all three estates. However, the third estate demanded that they should have more representation in the government, and they should be treated equally.

4. Tennis Court Oath:
The third estate was denied a separate meeting hall, so they decided to form their own assembly, the National Assembly. On June 20, 1789, the members of the National Assembly took the Tennis Court Oath, vowing not to disband until they had written a constitution for France.

Conclusion:

In conclusion, the National Assembly was formed to address the economic and political crisis in France. The third estate demanded representation in the government and equal treatment. The National Assembly was an important step towards the French Revolution, which ultimately led to the downfall of the absolute monarchy and the birth of democracy in France.
