Paulus Hungarus was a thirteenth-century Hungarian theologian and friar belonging to the Dominican Order. Born around 1180, he became a prominent jurist of canon law. His intellectual contributions include the authorship of the *Summa poenitentiae* and significant annotations for the *Compilatio I-III* collection. Beyond his academic work, he sought to strengthen religious orthodoxy within the Kingdom of Hungary by organizing a system of monasteries intended to defend against heresy.
