Kaliman Asen I, also known as Coloman Asen I or Koloman (Bulgarian: Калиман Асен I; 1234-August/September 1246) was Emperor (Tsar) of Bulgaria from 1241 to 1246. He was the son of Ivan Asen II of Bulgaria and Anna Maria of Hungary. He was only seven when he succeeded his father in 1241. In the following years, the Mongols invaded Bulgaria and imposed a yearly tax on the country. He may have been poisoned, according to contemporaneous rumors about his death.
