The Siege of Termes was a military engagement which took place from August to November 1210 during the Albigensian Crusade. It took place in the Languedoc region of southern France at the Castle of Termes. The Siege was led by Simon de Montfort as part of the Crusader effort to eliminate Catharism, a Christian sect regarded as heretical, from Southern France. After nearly four months of siege, the castle fell on the 22nd of November.
