Final answer:
From 600 to 1450 C.E., Christianity's social structure evolved with the Church consolidating power and influencing literacy and culture. The Black Death occasioned significant depopulation, yet European society recovered, leading to increased trade and societal changes. Technological and agricultural advances contributed to population growth and the eventual decline of feudalism.
Step-by-step explanation:
The period from 600 C.E. to 1450 C.E. witnessed significant alterations in the social structure of Christianity. During this era, the Church became the epicenter of power, stretching its influence from today's Turkey to Western and Northern Europe. The increased literacy among monks and the aristocracy, backed by the Church, fostered a religiously centered intellectual climate. With Pope Leo III crowning Charlemagne in 800, the Church reinforced its control, often punishing those challenging its beliefs.
Social and economic turmoil ensued in the form of the bubonic plague in the 1340s, taking a substantial toll on Europe's population. Despite this devastation, population and trade eventually rebounded, setting the stage for profound societal change. Meanwhile, religious life was challenged, with divisions within Christianity becoming more pronounced, and in the 16th century, the Reformation would fundamentally shake the Church's authority.
Advances during the High Middle Ages in technology and agriculture spurred population growth and the development of societal structures like manorialism and feudalism. However, the profound disparities within the feudal system eventually gave way to enhanced social mobility and the reduction of the feudal divide leading up to the 1450s.
