Fort Necessity (US)
Rival claims between the French and the English to the vast territory along the Ohio River between the Appalachian Mountains and the Mississippi approached a climax about 1750.
Fort Necessity was built in 1754 in an attempt of the British to regain control of the area form the French, who had built Fort Presque Isle near Lake Erie and Fort Le Boeuf in that part of the Ohio country claimed by Virginia. The French force immediately drove off the Virginians and built a larger fort on the site. Among others, this led to the war between the French and the British. Terrorized settlers streamed eastward and the war spread. In the ensuing decade, however, France lost all her colonies in North America and the British Empire was expanding around the globe.
