Title:
French_and_Indian_War

Context:
The Iroquois sent runners to the manor of William Johnson in upstate New York. The British Superintendent for Indian Affairs in the New York region and beyond, Johnson was known to the Iroquois as Warraghiggey, meaning "He who does great things." He spoke their languages and had become a respected honorary member of the Iroquois Confederacy in the area. In 1746, Johnson was made a colonel of the Iroquois. Later he was commissioned as a colonel of the Western New York Militia. They met at Albany, New York with Governor Clinton and officials from some of the other American colonies. Mohawk Chief Hendrick, Speaker of their tribal council, insisted that the British abide by their obligations and block French expansion. When Clinton did not respond to his satisfaction, Chief Hendrick said that the "Covenant Chain", a long-standing friendly relationship between the Iroquois Confederacy and the British Crown, was broken.
