The Ohio Company, formally known as the Ohio Company of Virginia, was a land speculation company organized for the settlement by Virginians of the Ohio Country (approximately the present state of Ohio) and to trade with the Native Americans. The company had a land grant from Britain and a treaty with Indians, but France also claimed the area, and the conflict helped provoke the 'outbreak' of the French and Indian War.
Virginian explorers recognized the potential of the Ohio region for colonization and moved to capitalize on it, as well as to block French expansion into the territory. In 1748,Thomas Lee and brothers Lawrence and Augustine Washington organized the Ohio Company to represent the prospecting and trading interests of Virginian investors.
In addition to the mandate and investment of Virginia Royal Governor Robert Dinwiddie, other original members included John Hanbury, Colonel Thomas Cresap, George Mercer, John Mercer, and "all of His Majesty's Colony of Virginia." In that same year, George Mercer petitioned King George for land in the Ohio country, and in 1749, the British Crown granted the company 500,000 acres in the Ohio Valley between the Kanawha River and the Monongahela. The grant was in two parts: the first 200,000 acres were promised, and the following 300,000 acres were to be granted if the Ohio Company successfully settled one hundred families within seven years. Furthermore, the Ohio Company was required to construct a fort and provide a garrison to protect the settlement at their own expense. But the land grant was rent and tax free for ten years to facilitate settlement.
