What are Robespierre and the Jacobin most known for?

Maximilien Robespierre and the Jacobins are most known for their leading role during the French Revolution, particularly during the Reign of Terror from 1793 to 1794. Robespierre, as a prominent Jacobin leader, advocated for radical political and social reforms, emphasizing virtue and equality while justifying the use of terror against perceived enemies of the revolution. Their methods included widespread arrests and executions, particularly through the guillotine, which aimed to eliminate counter-revolutionary threats. Ultimately, Robespierre's fall from power in 1794 marked the end of the Jacobin era and a shift in the revolution's direction.
