Massachusettes was the first colony to "officially" legalize slavery in 1641. But, the first slaves in the British colonies were brought to Jamestown, Virginia in 1619.
Technically, what is commonly referred to as "soul food" is actually Southern-style cooking originated by African Americans. Sometime in the 1960's, that style of cooking was renamed "soul food" in honor of the people that prepared food in the south during the slave period up until and before the civil war ended and the abolition of slavery was the law of the land.
I hate to muddle up things with facts of history, but I just did.
