Though the National Assembly held debates and discussions on the abolition of slavery, it did not make any law fearing opposition from the businessmen, whose income depended on slave trade. It was in 1794 that the Convention passed a law to free all slaves in French overseas possessions. But this lasted only for 10 years because when Napoleon Bonaparte became the emperor of France in 1804, he reintroduced slavery. In 1848, Slavery was finally abolished in French colonies.

The National Assembly, formed during the French Revolution, played a crucial role in transforming French society and governance. However, the statement that the National Assembly abolished slavery in France is incorrect. Here's why:

1. Formation of the National Assembly:
The National Assembly was formed in June 1789, as a result of the Estates-General. It was a representative body that aimed to create a constitutional monarchy in France and limit the power of the monarchy.

2. Abolition of the Feudal System:
One of the significant achievements of the National Assembly was the abolition of the feudal system. The feudal system was a social and economic structure that involved obligations and taxes imposed on peasants by the aristocracy. The National Assembly's actions, such as the August Decrees of 1789, abolished feudal privileges, serfdom, and the seigneurial rights of the nobility.

3. Confiscation of Church Lands:
To alleviate France's financial crisis, the National Assembly confiscated the land owned by the Catholic Church. This action was taken through the Civil Constitution of the Clergy in 1790, which declared that the Church's property would be nationalized and sold to support the state. This move significantly reduced the influence of the Catholic Church in France.

4. Drafting of the Constitution:
The National Assembly also played a pivotal role in drafting the constitution for France. They worked on the Constitution of 1791, which established a constitutional monarchy and limited the powers of the king. This marked a significant shift in governance, as it aimed to establish a more representative and accountable system.

5. Slavery in France:
However, the National Assembly did not abolish slavery in France. Slavery was not immediately addressed during the early stages of the French Revolution. It was not until 1794, under the leadership of the Committee of Public Safety, that the French Convention abolished slavery in French colonies through the Law of 16 Pluviôse, Year II.

In conclusion, the National Assembly did not abolish slavery in France. While it made significant reforms such as abolishing the feudal system, confiscating church lands, and drafting a constitution, the abolition of slavery came later in the French Revolution.
