Christopher Gist served as representative for the Ohio Company of Associates at the Logstown treaty meeting in the colony of Pennsylvania held in May 1752. Gist's instructions directed him to inform the several tribes of Indians expected at the meeting, including the Six Nations, the extensive grant of land on the Ohio to the Ohio Company for establishing colonial settlements and increase of trade in the region. The point of the meeting was to create a stable frontier environment for extension of commerce and settlement along the Ohio. For Gist's part, he was to emphasize the benefits to the Indians of expanded trade and increased white settlement.

February 19, 1754 | Statute Proclimation [sic] of 1754 In response to the perceived threat of French incursions into the Ohio valley, Governor Dinwiddie issued this proclamation offering bounty lands to "all who should voluntarily enter into ... service" for the establishment of a fort on the Ohio where it met the Mohongahela. The bounty lands included two hundred thousand acres near the fort and along the river. Each enlistee would receive land "in a proportion due to their respective merit."

August 29, 1755 | Statute An act preventing and repelling the hostile incursions of the Indians, at enmity with the inhabitants of this colony. The law addresses ongoing violence between Virginians and native groups "supposed to be in the interest of the French." Bounty is offered to Virginians for the capture and killing of any enemy male over the age of twelve. To safeguard relationships with allies, the Assembly decrees that anyone who "knowingly and wilfully" kills any Native male "in alliance, peace and friendship with his majesty and his subjects in this colony" will be prosecuted as a felon.

October 29, 1755 | Statute An act for preventing and repelling the hostile incursions of the Indians, at enmity with the inhabitants of this colony.

October 7, 1763 | Treaty Proclamation of 1763. In the aftermath of the French and Indian War, the British crown issued this proclamation, which severely limited colonists' access to land west of an imaginary line running down the crest of the Appalachain Mountains. With this attempt to reorganize British control in North America and maintain orderly relations with Native peoples, George III further alienated colonists who saw western expansion as an inevitable process. Many provisions in the Proclamation remained intact until 1776, although incursions by colonists into land west of the Proclamation Line were common.

October 5, 1765 | Statute An act for establishing a trade with the Indian allies of his majesty, and to amend another act directing the trustees of the Indian Factory of Virginia.

The trustees of the Indian Factory are instructed to limit the types of goods sold and the manner in which they deal with established allies and new consumers.

May 3, 1779 | Statute An act for declaring and asserting the rights of this commonwealth, concerning purchasing lands from Indian natives. Virginia's revolutionary government claimed an "exclusive right of preemption" over all lands within the bounds of its "chartered territory," including the lands north and west of the Ohio River. Moreover, the act made null and void every land transaction between individuals and the various tribes of Indians, or grants from English crown to any individual within the commonwealth, transferring control of all such lands into the hands of the commonwealth.

May 3, 1779 | Statute An act for establishing a Land office, and ascertaining the terms and manner of granting waste and unappropriated lands. Concerned about the disposal of "waste and unappropriated lands," the General Assembly created a land office to deal with the sale and distribution of these lands. The lands would be used to encourage immigration, increasing public revenue, and paying off the commonwealth's debt. The office's administrative role would be essential to managing records of land patents, grants, veterans' land warrants, and purchases of waste and unappropriated lands sold at forty pounds per hundred acres. Managing Virginias lands, and later the public lands of the United States, was a central concern throughout the dcades of the early republic.
