Subsequent to this insurrection, and to the September Massacres that followed closely on its heels, the Cordeliers Club became increasingly the province of ultra-revolutionary factions, particularly the Hébertists, who advocated extreme measures to intensify the Terror.
Now known as the atheist Cult of Reason ideology, established by Jacques Hébert, Pierre Gaspard Chaumette and their supporters and intended as a replacement for Christianity, and was replete with ceremonious destruction of Christian relics, conversion of churches into Temples of Reason and the personification of Reason as a goddess; it also held such festivities as the Festival of Reason (or Festival of Liberty), dated on November 10 (20 Brumaire) 1793.
When the Committee of Public Safety, under Robespierre's direction, levelled accusations of treason against the Hébertists, they also implicated Cloots to give substance to their charge of a foreign plot.
