In 1869, Vladimir Stasov, a major literary figure of 19th-century Russia, suggested to Alexander Borodin that an opera might be written on the subject of the "Lay of Igor’s Campaign". Borodin began to write his "Prince Igor" but he left the opera unfinished at the time of his death nearly twenty years later. It fell to Nikolai Rimsky-Korsakov and Alexander Glazunov to finish the orchestration and prepare "Prince Igor" for publication and performance in 1890.
