What was the civil about?

I assume you mean what was the Great Awakening, so here it is:

The term Great Awakening is used to refer to a period of religious revival in American religious history. Historians and theologians identify three or four waves of increased religious enthusiasm occurring between the early 18th century and the late 20th century. Each of these "Great Awakenings" was characterized by widespread revivals led by evangelical Protestant ministers, a sharp increase of interest in religion, a profound sense of conviction and redemption on the part of those affected, a jump in evangelical church membership, and the formation of new religious movements and denominations.

First Great Awakening
Main article: First Great Awakening

The First Great Awakening began in 1720 and lasted to about 1750. Ministers from various evangelical Protestant denominations supported the Great Awakening.[1] Additionally, pastoral styles began to change. In the late colonial period, most pastors read their sermons, which were theologically dense and advanced a particular theological argument or interpretation. Leaders of the Awakening such as Jonathan Edwards and George Whitefield had little interest in merely engaging parishioners' minds; they wanted far more to elicit an emotional response from their audience, one which might yield the workings and evidence of saving grace. They also wanted to see people who were noticeably moved in the audience and stood out amongst the rest.

The idea of an "awakening" implies a slumber or passivity during secular or less religious times. Thus, awakening is a term which originates and is embraced often and primarily by evangelical Christians.[6] In recent times, the idea of "awakenings" in US history has been put forth by conservative US evangelicals.[7]
