Trace the history of christianity to the coronation of charlemagne in 800. what distinctive features characterized the early church? what role did the church play in the world after the fall of the western roman empire?

Establishment of Catholic orthodox, which required Christians to be baptized, partake of Eucharist, and call Jesus Lord; also required acceptance of creed, canonical writings, and authority of bishops; Rome made center of Christianity based on Peter's martyrdom there and Jesus' calling him the rock upon which his church would be built

b) The Goths had already taken up Christianity and helped spread it to other tribes; strong organization and influence of Roman church helped to keep Christianity afloat in the West

answer:   migrations were important in the neolithic period. "two major migrations passing through southeastern europe were confirmed by the means of archaeo-genetic studies."

the first migration was the early neolithic period -- 6,000 before common era (bce) -- when the first farmers, from anatolia -- asia minor -- spread through europe. the second migration occurred during the early bronze age (3,000-2,500 bce) when the so-called "steppe population," from the eurasian steppe, replaced much of northern europe's previous population.

the first farmers of northern and western europe passed through southeastern europe with limited hunter-gatherer genetic admixture, which occurs when two or more previously isolated populations begin interbreeding. however, some groups that remained mixed extensively -- without the male-biased, hunter-gatherer admixture that prevailed later in the north and west, according to latest discoveries. southeastern europe continued to be a nexus between east and west, with intermittent genetic contact with the steppe people up to 2,000 years before the migrations that replaced much of northern europe's population.

"in some places, hunter-gatherers and incoming farmers seem to have mixed very quickly," says iain mathieson, a geneticist at the university of pennsylvania, who was first author of the paper. "but, mostly, the two groups remained isolated, at least for the first few hundred years. these hunter-gatherers had been living there for thousands of years, and it must have been quite a shock to have these new people show up -- with a completely different lifestyle and appearance."
