Who won the trinitarians or the arians?

The Trinitarians ultimately prevailed in the theological debates of the early Christian church, particularly during the Council of Nicaea in 325 AD, which affirmed the doctrine of the Trinity. This council condemned Arianism, which denied the full divinity of Jesus Christ. Over time, the Nicene Creed became a foundational statement of Christian orthodoxy, solidifying the Trinitarian view as dominant in mainstream Christianity. However, Arianism continued to have followers and influence in various regions for centuries.
