Carmen miserabile super destructione regni Hungariae per Tartaros (Latin for "Sad Song for the Destruction of the Kingdom of Hungary by the Tartars") is an account written by Rogerius of Apulia. After 1241, Rogerius wrote a description of the conquest of Transylvania and the Great Hungarian Plain by the Tatars in this work. Mongol-Tatar Golden Horde forces led by Batu Khan began attacking Europe in 1223, starting with Kievan Rus. They continued to defeat the German principalities, Polish, and Hungarian armies before turning back to go home in 1241.
