In November 1676, Jeffreys was appointed by Charles II as a lieutenant governor of Virginia colony. He arrived in Virginia in February 1677, in response to
Bacon's Rebellion. Jeffreys commanded a regiment of six warships carrying over 1,100 troops, and was tasked with quelling and pacifying the rebellion. He served as leader of a three-member commission (alongside
Sir John Berry and
Francis Moryson) to inquire into the causes of discontent and political strife in the colony. The commission published a report for the King titled
"A True Narrative of the Rise, Progresse, and Cessation of the late Rebellion in Virginia," which provided an official report and history of the insurrection. On 27 April 1677 and with the support of the King, Jeffreys assumed the role of acting colonial governor, succeeding Governor
Sir William Berkeley, who was formally recalled to England and convinced to vacate the colony, but who died not long after disembarking in London. Shortly after Jeffreys took over as acting governor, Berkeley angrily remarked that Jeffreys had an "irresistible desire to rule this country" and that his action could not be justified. He wrote to Jeffreys, "I believe that the inhabitants of this Colony will quickly find a difference between your management and mine." As acting governor, Jeffreys was responsible for appeasing the remaining factions of resistance and reforming the colonial government to be once more under direct
Crown control. As acting governor, Jeffreys presided over the
Treaty of 1677, the formal peace treaty between the Crown and representatives from various Virginia
Native American tribes that was signed on 28 May 1677. In January 1678 he recommended it be expanded to neighboring English colonies. Meanwhile, in October 1677, Jeffreys persuaded the
Virginia General Assembly to pass an act of amnesty for all of the participants in Bacon's Rebellion, and levied fines against any citizen of the colony that called another a "traitor" or "rebel." Jeffreys also led efforts to rebuild and restore the state house and colonial capital of
Jamestown which had been burned and looted during the rebellion. As acting governor, Jeffreys was known for suspending some of his most outspoken critics from office. == Death and legacy ==
