<entity_0>, also called the Crusade of <entity_1>, was in territorial terms the most successful crusade since the First Crusade. This crusade to the <entity_3> is sometimes discussed as two separate crusades: that of King Theobald I of Navarre, which began in <entity_1>; and, the separate host of crusaders under the leadership of Richard of Cornwall, which arrived after Theobald departed in 1240. Additionally, the <entity_2> was wildly unpopular among the native Christian leaders because the excommunicated Frederick left them defenseless, allied with their Muslim enemies, and attempted to gain control over the <entity_3> for the House of Hohenstaufen rather than restore the territories to the local barons of the Kingdom of Jerusalem. Therefore, in 1234, Pope Gregory IX proclaimed that a new crusade should arrive in the <entity_3> by <entity_1> to ensure Christian control. When the complete army reached <entity_5> on <entity_1>, a subset of the army wanted to conduct a raid of their own. His work done, Richard departed at <entity_6> for England on 3 <entity_4>. At the beginning of July in <entity_1>, Baldwin of Courtenay the nineteen-year-old heir to the Latin Empire and Marquis of Namur, travelled to Constantinople with a small army (three times smaller than <entity_0> expedition) including the five secular magnates Humbert of Beaujeu, Thomas of Marle, Josseran of Brancion, William of Cayeaux, and Watins of La Haverie.
