In 1230, Theodore was defeated and captured by Emperor Ivan Asen II in the battle of Klokotnitsa, and lands west of Adrianople were once again part of Bulgaria; all the way to Durrës, Ivan Asen wrote in a memorial column that he conquered "His Komnenos' whole land from Odrin (Edirne) to Drach (Durrës), also Greek, Albanian and Serb" after the victory. Between 1246 and 1265, John Vatatzes conquered Macedonia from the Adrianople to the Vardar, while the Bulgarian emperor Michael I Asen had the towns west of the Vardar: Veles, Prilep and Ohrid. In 1252 John overcame Michael, and most of Macedonia towards the border of Serbia became a Nicaean province. After the 13th century, the Bulgarian empire lost Macedonia.
