Changes

Never having the numerical support of most bishops, priests or laity to begin with, Arianism died out inside the Empire almost overnight, but continued to be a threat to the Roman Empire as many of the surrounding tribes had and were accepting Christianity, but were converted with an Arian stamp.

The barbarian tribes which invaded Rome, and caused its fall in 476, were often Arians.  They include the [[Visigoths]] and the [[Ostrogoths]], and especially [[Theoderic]].  Centuries passed before the trinitarians prevailed in those regions.  The 5th Ecumenical Council in 553 ended the last outreaches of Arianism within greater Europe.<ref>J.

Arianism died out as an organized force but its ideas were known to theologians. Arianism Unitarianism in [[Renaissance]] Europe grew out of the teachings of the Italians Lelio Sozzini, or Socinus (1525-1562), and his nephew Fausto (1539-1604) during the period of the [[Protestant Reformation]]. [[Isaac Newton]] was an Arian--indeed he modeled himself after Arius--but kept it secret because heresy would cost him his official academic and government appointments.

[[Unitarian]] ideas that emerged in England and the U.S. after 1770 have many similarities to Arianism.
