New York & Philadephia: Anti-Abolitionist Riots (1834-35) (9 nov 1834 – 7 sept. 1835)

Description:

"Both New York City and Philadelphia, Pennsylvania, experience riots against African Americans and anti-slavery advocates. Anti-abolition riots subsequently break out in major cities across the Northeast.

Many Northerners thought that immediate abolition would threaten the economy and culture of the U.S. Anti-abolitionist sentiment in many northern cities was also fueled by resentment of black freemen among recently arrived immigrants from Ireland."
