Why were woman so involved in the second great awakening?

The correct answer is women's involvement in the revival provided support for the women's rights movement.

Women, were the majority of converts during the Awakening, and played a crucial role in their development. It is not clear why women converted in greater numbers than men. The sense of religiosity in women, reaction to economic insecurity, or an affirmation of self in the face of the patriarchal rule. Husbands, especially in the South, sometimes failed to convert their wives, forcing women to choose between submission to God or their spouses. Church membership and religious activity gave women peers support and a place for meaningful activity outside the home, providing many women with a common identity and shared experiences.
