Slave Trade
The end of the the transatlantic slave trade also contributed to the slow demise of slavery in the North. In 1774 the First Continental Congress vowed to end the transatlantic slave trade. As a result, Connecticut and Rhode Island took legal action and prohibited the importation of slaves. By this point when slave trade was abolished, slavery in the North had already started to become unfavorable. Aside from the fact that there was heated moral protest on the issue of slavery, many Northerners simply did not find a need for slavery anymore. High attrition rates of slaves had already taken their tolls on the slaves in the North, and statistically the death rate of slave babies was twice that of white babies.With the end of the slave trade there was no new influx of slaves from Africa to replace to ones that were rapidly dying off. By 1790, 94% of U.S. slaves lived below the Mason-Dixon Line according to the National Census. It was becoming evident that the end of slavery in the North was fast approaching.
