Prince Igor was completed posthumously by Rimsky-Korsakov and Glazunov. It is set in the 12th century, when the Russians, led by Prince Igor of Seversk, set out to conquer the barbarous Polovtsians by travelling Eastward across the Steppes. The Polovtsians were apparently a Nomadic tribe originally of Turkish origin who habitually attacked southern Russia. A full solar eclipse early in the first act foreshadows an ominous outcome to the invasion. Prince Igor's troops are defeated. The story tells of the capture of Prince Igor, and his son, Vladimir, of Russia by Polovtsian leader Khan Konchak, who entertains his prisoners lavishly and calls on his slaves to perform the famous 'Polovtsian Dances', which provide a thrilling climax to the second act. The second half of the opera finds Prince Igor returning to his homeland, but rather than finding himself in disgrace, he is welcomed home by the townspeople and by his wife, Yaroslavna. Although for a while rarely performed in its entirety outside of Russia, this opera has received two notable new productions recently, one at the Bolshoi State Opera and Ballet Company in Russia in 2013, and one at the Metropolitan Opera Company of New York City in 2014.
