Which denomination minsitered primarily to laboring men and women in the mid nineteenth century?

Christianity

Explanation:

The essential unity of the evangelical orthodoxy of mid-century became a multiplicity under the influence of this impact and other factors. The changes which fostered, accompanied, and were produced by the industrial revolution -- such as urbanism and all that it implied -- put to stringent test the practices and institutional patterns of a Protestantism which had been closely identified with rural society and culture. The increase of the number of Americans with non-Protestant orientations created for the first time a condition in which Protestantism's domination of American culture could be challenged. Religious and cultural pluralism became a reality, and this affected the status of the Protestant minister in the American community.
