On 10 August 1792, an angry crowd threatened the palace of King Louis XVI, who took refuge in the Legislative Assembly. A Prussian Army invaded France later in August 1792. In early September, Parisians, infuriated by the Prussian Army capturing Verdun and counter-revolutionary uprisings in the west of France, murdered between 1,000 and 1,500 prisoners by raiding the Parisian prisons. The Assembly and the Paris City Council seemed unable to stop that bloodshed. The National Convention, chosen in the first elections under male universal suffrage, on 20 September 1792 succeeded the Legislative Assembly and on 21 September abolished the monarchy by proclaiming the French First Republic.
