Which colony legalized slavery in 1661

Virginia

Explanation:

The colony that legalized slavery in 1661 was Virginia. The first Africans to arrive to the colony did so in 1619. These were initially considered to be "indentured servants" in the same way in which many Europeans were at the time. However, in 1661, Virginia passed a law allowing free people to own slaves. Additional laws were later passed and eventually codified in the slave code of 1705.

i would say that the politicial parties from state to state varies.

if i am correct the answer is going to be a) the federal program of reconstruction ended.
