The first half of the 19th century in the U.S. produced a series of reform movements. These movements were motivated by the new ideas concerning religion, education, and societal values. The Second Great Awakening was a religious movement which challenged the Calvinist belief of predestination. The idea that ones' destiny to heaven or hell was 'predestined' at birth was replaced by the idea that men and women had control over their destinies. Each individual had the power within themself to choose to do good and not commit sin. The educational reforms led by Horace Mann suggested that education should not be just for the wealthy. Education should be funded by the government, inclusive to all, have grade standardization, and trained teachers. The American Temperance
Society saw alcohol as the root to many of society's problems and sought to prohibit consumption. In addition, prior to the Civil War the American Colonization Society strived to emancipate slaves and return them to Africa. It was from this effort that the abolitionist movement grew and became a reform force to be reckoned with, ultimately resulting in the 13th Amendment.

The abolitionist movement had a direct relationship with religious revivalism, but many other reform movements rose out of the Second Great Awakening. The temperance and suffrage movements both emerged during this period, as did prison and asylum reform. The move for public education as well as various urban reform efforts also arose during this time. It was during this period that utopian experiments like Robert Owen's New Harmony and the more radical Oneida Settlement briefly flourished, along with dozens of other settlements inspired by French socialist Charles Fourier. The period also saw the formation of religious sects who aimed to reform Christianity or set out on their own. These included the Mormons.

Please tell us more about what aspect of this you want discussed.

One thing that is of note is that many of the reform movements were dominated by women from the growing middle class.  These women were often motivated by religion because the Second Great Awakening had emphasized the idea that people should work to perfect the societies in which they lived.

Are you asking about religious reform or societal reform?  In the early nineteenth century, there were reforms centered on women's rights and ending slavery.  Part of the events that led to the Civil War involved increased abolitionist activity.  Some people began to look at slavery as morally wrong.

How did early 19th-century religious revivalism influence American socio-cultural identity and societal values?

I wonder if religion has had such a strong impact on American life because, in part, we have had such little religious conflict in this country. We have no longer history, as Europe has, of religious wars and even of relatively recent violent conflict due to religious differences (as in Northern Ireland).

Americans still think that we are better than everyone else, or that we can become better than everyone else.  I agree with post #2 that we expect perfection.  As the saying goes, Americans are the only people that expect to be happy.  Maybe it is our sense of rugged idealism since our country started.

I think that these have helped to make us something of a utopian people.  We think that we can and should have everything be perfect.  That's good because it makes us strive for better things.  But it's bad because it makes us angry at the government and disillusioned/cynical when things aren't perfect.
