What revolution is referred to here

The French Revolution (French: Révolution française  began in May 1789 when the Ancien Régime was abolished in favour of a constitutional monarchy. Its replacement in September 1792 by the First French Republic led to the execution of Louis XVI in January 1793, and an extended period of political turmoil. This culminated in the appointment of Napoleon as First Consul in November 1799, which is generally taken as its end point. Many of its principles are now considered fundamental aspects of modern liberal democracy.[1]
