The new emperor’s attempts to offer the Byzantine church to Rome was met with stiff resistance, and Alexius IV was strangled in early 1204. In reaction to this, the Crusaders declared war on Constantinople, and this ended the Fourth Crusade with the conquest and raid of the Byzantine capital later in the year (History.com). The fourth lasted from 1201 until 1204 (Trueman). There was never a greater crime against humanity than the fourth crusade (Runciman 130).

The Albigensian Crusade which was from 1208 until 1229 aimed to rule out the heretical Cathari or Albigensian group of Christianity in France.

The Mamluks demolished Antioch in this year, persuading Louis IX to set out on another Crusade, which ended in his death. A new Mamluk, Qalawan, had defeated the Mongols by the end of 1281 and led his attention back to the Crusaders, capturing Tripoli in 1289.
