''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
Kyivan Rus'. They continued to defeat
German,
Polish, and
Hungarian armies before turning back to go home, upon learning of the death of their Great Khan in
1241.
