The University of Nicaea was established in 325 AD during the First Council of Nicaea, which aimed to address various theological disputes within early Christianity. Located in Nicaea, present-day Iznik, Turkey, it played a significant role in the development of Christian doctrine and education. The university was notable for its emphasis on philosophy and theology, attracting scholars from various regions. It contributed to the formation of early Christian teachings and the establishment of the Nicene Creed, which remains a foundational statement of faith in many Christian denominations today.
