Francois Furet quotes:

Louis XVI started to die on June 21st 1791. For his flight tore away the veil of that false constitutional monarchy, and once more confronted the Patriot party with the whole problem of the revolution's future.

For the same reason that the Ancien Regime is thought to have an end but no beginning, the Revolution has a birth but no end.

The August Decrees were an improvised parliamentary reaction to an emergency situation.
