In 1793, the French Revolution and its ideas were being spread throughout Southern France. However, with the beginning of the Reign of Terror, anyone accused of anti-revolutionary sentiments was murdered. In the South of France especially, many pro-revolution supporters began to oppose the tyrannical and unhuman behaviour of The Mountain, the left-wing radical party controlling France since the Insurrection of 31 May–2 June. The subsequent takeover and complete control of Maximilien Robespierre lead to country-wide Federalist revolts. At the strategically important Naval Base in Toulon, Provence, the entirety of the Toulon National Guard revolted and handed over their area to the Allies. The allies arrived, and in late August 1793, the Siege of Toulon started, and with no end in sight, Allied support for the city grew, and several local units began to form.
