Saul is a dramatic oratorio in three acts written by George Frideric Handel with a libretto by Charles Jennens. Taken from the First Book of Samuel, the story of Saul focuses on the first king of Israel's relationship with his eventual successor, David—one which turns from admiration to envy and hatred, ultimately leading to the downfall of the eponymous monarch. The work, which Handel composed in 1738, includes the famous "Dead March", a funeral anthem for Saul and his son Jonathan following their deaths in the Battle of Mount Gilboa at the hands of the Philistines, and some of the composer's most dramatic choral pieces. Saul premiered successfully at the King's Theatre in London on 16 January 1739, and was revived by Handel in subsequent seasons. Notable modern-day performances of Saul include that at Glyndebourne in 2015.

George Frideric Handel was a German-British Baroque composer well known for his operas, oratorios, anthems, concerti grossi, and organ concertos. Handel received his training in Halle and worked as a composer in Hamburg and Italy before settling in London in 1712, where he spent the bulk of his career and became a naturalised British subject in 1727. He was strongly influenced both by the middle-German polyphonic choral tradition and by composers of the Italian Baroque. In turn, Handel's music forms one of the peaks of the "high baroque" style, bringing Italian opera to its highest development, creating the genres of English oratorio and organ concerto, and introducing a new style into English church music. He is consistently recognized as one of the greatest composers of his age.
