The French Republic was formed through the declaration of which institution?

Correct answer: National Convention

The direct answer is the National Convention, so option A is correct. After the monarchy was suspended in 1792, elections were held for a new representative body called the National Convention. This body met in September 1792 and formally declared France a republic. A republic is a government without a hereditary king as its head. Option A works because the National Convention was the institution that made the declaration. Option B, the Bastille prison, was a building and symbol of royal authority; it was stormed in 1789, but it did not declare the republic. Option C, the Estates-General of 1614, was an earlier representative assembly and did not create the French Republic in 1792. Option D, the Tuileries Palace, was a royal residence, not a law-making institution. The key distinction is between a place where an event happened and the institution that made an official political decision. The National Convention replaced the Legislative Assembly and represented the revolutionary nation. Remember: Convention means the body that conventionally declared the republic in 1792.
