The Siege of Carcassonne was a military engagement which took place from August 1, 1209, to August 15, 1209, during the Albigensian Crusade. It took place in the Languedoc region of southern France at the fortified town of Carcassonne. The Siege was led by Arnaud Amaury as part of the Crusader effort to eliminate Catharism, a Christian sect regarded as heretical, from Southern France. After intense fighting, the siege ended in a negotiated surrender, and the inhabitants were allowed to leave free of harm.
