Because
of different religions and culture, schooling was hard to maintain and
establish in United States. National leaders wanted to make education
compulsory to everyone to make good citizens and leadership out of the
children. To make education a primary goal, the Congress sanctioned the Land

the maintenance on public schools. It is also at this ordinance where religion
and state were separated making religion not a compulsory in their education’s
curriculum.
