The correct answer to this open question is the following.
The creation of representative democracy in colonial America contributed to the institutionalization of slavery in the following way.
The General Assembly in the Jamestown, Virginia colony started its works in July 1619. People voted for their representatives, called in that colony "Burgesses." One month later of this election, the first African slaves arrived in Jamestown to work in the farm fields. Many colonial farmers saw the advantages of having Africans as indentured workers in the tobacco plantations. And this form of "slavery" began to be accepted in the colony.
Tobacco was the king of crops in Jamestown, Virginia. This was high-quality tobacco very much accepted in England, so most of the crops were exported to England. That is why plantation owners needed Africans to satisfy exportation demands.
