What conditions in the north might explain the many roles taken on by the black church in the 1800’s

Discrimination and Restrictions to black people.

Explanation:

In the northeastern states, blacks faced discrimination in many forms. Segregation was rampant, especially in Philadelphia, where African Americans were excluded from concert halls, public transportation, schools, churches, orphanages, and other places. Blacks were also forced out of the skilled professions in which they had been working. And soon after the turn of the century, African American men began to lose the right to vote -- a right that many states had granted following the Revolutionary War. Simultaneously, voting rights were being expanded for whites. New Jersey took the black vote away in 1807; in 1818, Connecticut took it away from black men who had not voted previously; in 1821, New York took away property requirements for white men to vote, but kept them for blacks. This meant that only a tiny percentage of black men could vote in that state. In 1838, Pennsylvania took the vote away entirely. The only states in which black men never lost the right to vote were Maine, New Hampshire, Vermont and Massachusetts.
