Anti-Abolitionist Riots (mar 17, 1834 – feb 18, 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."
