30-year peace treaty concluded with Pechenegs (at Byzantine or Pecheneg suggestion?)

Summary:
Konstantinos IX was upset at the defeat of his army under Michael the akolouthos and Basileios synkellos by the Pechenegs of Tyrach. He gathered fresh troops and mercenaries, and would not calm down until he wiped out the Pecheneg race. The news was taken to them by a renegade. The Pechenegs may also have been impressed by Botaneiates' spectacular escape. The result was a 30-year peace. Attaleiates gives the initiative to Konstantinos, who decided not to send any troops to fight the enemy, made agreements with them to put an end to the war, and granted them gifts and honours. Skylitzes, who emphasises the story of Konstantinos' determination reported by a renegade, speaks of an embassy from the Pechenegs seeking peace
