During the summer of 1792, the Jacobins planned an armed rebellion of a large number of Paris people who were angry with the short supplies and high prices of food. On August 10, they stormed the palace of the Tuileries, killed the king’s guards and kept the king as hostage for many hours. Later the Assembly voted to imprison the King’s family. New elections were held. From now on all men of 21 years and above, regardless of wealth, got the right to vote.
The newly elected assembly was called the Convention. On 21st September 1792, it abolished the monarchy and declared France a Republic.
