However, the Pecheneg alliance failed, and Leo Phokas was crushingly defeated in the Battle of Anchialus and again at Katasyrtai in 917. Zoe tried to ally with Serbia and the Magyars against Simeon.

A humiliating treaty with the Arabs of Sicily, who were asked to help subdue revolts in Italy, did little to improve the position of Zoe and her supporters.
