Anthony Johnson came to the colonies as an indentured servant from Angola. When his contract was paid he was given a farm and contracted an indentured servant for himself.
A fire on Johnson’s farm destroyed the record of the contract with his indentured servant and Johnson refused to release the man. The case went to court and the court found in favor of Johnson who declared that the indentured servant’s debt could never be paid off. True slavery in America was born.
So the first liberal/slave evolved.
