In 1177, Odon joined the revolt of the Lesser Polish nobility against his own father, Mieszko III, because of the favoritism Mieszko III had shown to the offspring of his second marriage.
Little is known about Odon's reign over Kalisz beyond the fact that he founded a mint, where coins have been recovered bearing the inscription "Odon Dux" ("Duke Odon")-suggesting a high degree of autonomy.
