Jerusalem Delivered (Italian: La Gerusalemme liberata [la dʒeruzaˈlɛmme libeˈraːta]) is an epic poem by the Italian poet Torquato Tasso, first published in 1581, that tells a largely mythified version of the First Crusade in which Christian knights, led by Godfrey of Bouillon, battle Muslims in order to take Jerusalem. 
 

The work belongs to the Italian Renaissance tradition of the romantic epic poem, and Tasso frequently borrows plot elements and character types directly from Ariosto's Orlando furioso. Tasso's poem also has elements inspired by the classical epics of Homer and Virgil (especially in those sections of their works that tell of sieges and warfare). One of the most characteristic literary devices in Tasso's poem is the emotional conundrum endured by characters torn between their heart and their duty; the depiction of love at odds with martial valour or honor is a central source of lyrical passion in the poem.
 

Tasso's choice of subject matter, an actual historic conflict between Christians and Muslims (albeit with fantastical elements added), had a historical grounding and created compositional implications (the narrative subject matter had a fixed endpoint and could not be endlessly spun out in multiple volumes) that are lacking in other Renaissance epics. Like other works of the period that portray conflicts between Christians and Muslims, this subject matter had a topical resonance to readers of the period when the Ottoman Empire was advancing through Eastern Europe.

The poem was hugely successful, and sections or moments from the story were used in works in other media all over Europe, especially in the period before the French Revolution and the Romantic movement, which provided alternative stories combining love, violence, and an exotic setting.
