Augustin Kažotić was a 13th-century Dominican prelate who served as the Bishop of Zagreb and later the Bishop of Lucera. Born in Trogir, he was a learned humanist and orator who studied in Paris before dedicating himself to missionary work in the regions of modern Bosnia and Herzegovina. Throughout his ecclesiastical career, he was recognized for his commitment to education, his defense of the poor, and his efforts to combat heresy through teaching rather than punishment.
