The first establishment in Virginia which became permanent was made in 1607. I have found no mention of negroes in the colony until about 1650. The first brought here as slaves were by a Dutch ship; after which the English commenced the trade and continued it until the revolutionary war. That suspended, ipso facto, their further importation for the present, and the business of the war pressing constantly on the legislature, this subject was not acted on finally until the year 78. when I brought in a bill to prevent their further importation. This passed without opposition, and stopped the increase of the evil by importation, leaving to future efforts its final eradication.
Patrick Lee’s Explanation
Determined leaders remain committed to their causes over time.
In 1769, Jefferson had been on the losing side of a slavery-limiting issue in the Virginia House of Burgesses. In 1778, he was the successful author of a bill to prohibit further importation of slaves into the state. He recognized this was not the ultimate goal but rather a step in that direction.
