Major Events

1. Division of the Empire, which both lead to a quicker disintegration of the power base and coherence of the western half, but also allowed the eastern half to continue to exist for another millennium.  The western half, more sparsely populated with fewer urban centers and more porous borders, was therefore, also more vulnerable to invasions. The eastern half cut free from this, was able to consolidate its forces over a more defensible area and to organize its districts in a more administrable radius from the new imperial center.
   
2. Christianity Adopted as Religion of Empire, leading to an important series of cultural shifts for both empire and church, including the institutionalization of the Christian faith and the impact of broad Christian beliefs and new social structures upon future European civilization.
   
3. The Ecumenical Councils, a clarification of the doctrines of the Trinity, the two natures of Christ, and the appropriate place of images within worship. The Councils also represent some of the first divisions within the Christian religion.
   
4. Barbarian Invasions and Establishment of Kingdoms, the shifting political structures that lead to the fall of the western half of the empire, as well as the eventual rise of new power bases and cultural milieus.
   
5. Rise and Spread of Monasticism enabled 1) the continuation of some elements of classical education, 2) the development of early corporation economic structures, and 3) the perpetuation of a spiritual-temporal dualism in Christian understandings of vocation and culture.
   
6. Rise and Spread of Islam represented a continual source of cultural, religious, and political pressure on medieval Europe . It displaced much of Syrian and North African Christianity, constituted a superior civilizational threat in several periods of European history, and eventually enabled the recovery of several important Greco-Roman insights into European thought.
   
7. The Carolingian Renaissance, the first large center of political, pedagogical, and religious renewal following the fall of the western Roman Empire. Its formation would shape the future course of European political and national development, as well as constitute an albeit short-lived cultural flowering of education, writing, and art.
