Name two things brought back from crusades

The Crusades were a series of religious wars initiated, supported, and sometimes directed by the Latin Church in the medieval period. The term refers especially to the Eastern Mediterranean campaigns in the period between 1096 and 1271 that had the objective of recovering the Holy Land from Islamic rule. The term has also been applied to other church-sanctioned campaigns fought to combat paganism and heresy, to resolve conflict among rival Roman Catholic groups, or to gain political and territorial advantage. The difference between these campaigns and other Christian religious conflicts was that they were considered a penitential exercise that brought forgiveness of sins declared by the church. Historians contest the definition of the term "crusade". Some restrict it to only armed pilgrimages to Jerusalem; others include all Catholic military campaigns with a promise of spiritual benefit; all Catholic holy wars; or those with a characteristic of religious fervor.
