Monothelitism

Monothelitism was the christological doctrine that Christ had one will but two natures (divine and human). Under the influence of the Patriach Sergios (of Constantinople), monothelitism was developed during the reign of Heraclius as a response to Monoenergism and as an attempt to reconcile the Monophysites with the Chalcedonians. However, it was rejected by the Catholic and Eastern Orthodox churches, and was never accepted by most of the monophysites either. One prominent opponent of the doctrine was Maximus the Confessor.
