Answer:
C. It is a time in American history from the late 18th century until the start of the Civil War.
Explanation:
As per the American history, the Antebellum Period is commonly regarded to be the time before the Civil War and after the Constitution was adopted in 1789. It was associated with the rise of abolition and the country's gradual division between the slavery supporters and abolitionists. The conquest of new territories and western expansion intensified the slavery issue and contributed to the Civil War.
This resulted in an increase in the transformation of
communities due to the influx of new immigrants many of whom were at an age
where they are about to establish their own independence and make their own
mark in their new home.
I that it comes from the fact that America was supposed to
be the country where all men are free and equal but when it comes to Blacks,
that does not apply. Despite fighting a
war that restored the Union and freed the slaves, Blacks still did not enjoy
the same rights as white men hence the contradiction.
