Answer:
The First Great Awakening was lead by Jonathon Edwards in the 1730's and 1740's and impacted both sides of the Atlantic and involved a move away from ritual and doctrine as central to the religious experience and toward a personal religion fostering a deep sense of spiritual guilt and redemption, and encouraging introspection and a commitment to a new standard of personal morality.
The Second Great Awakening occurred during the early 1800's in the US and expressed an theology of individual salvation through revivals.
