The Warmian bishops were the ecclesiastical leaders of the Warmia region in northern Poland. They played a significant role in the Catholic Church during the Middle Ages and the early modern period, overseeing religious, political, and social matters in their diocese. The bishops were influential figures, often involved in local governance and the promotion of education and culture. The most notable of the Warmian bishops was Nicolaus Copernicus, who served as a canon in the cathedral chapter. His contributions to astronomy and science were significant, and he is best known for proposing the heliocentric model of the solar system. The Warmian bishops' legacy includes their impact on both the church and the broader community in the region.
