Early in the summer of 1754, on the eve of the French and Indian War, Weiser was a member of a Pennsylvania delegation to Albany. London had invoked the meeting, hoping to win assurances of Iroquois support in the looming war with the French. Present were representatives of the Iroquois and seven colonies. Because of divisions within both the British and Native American ranks, the council did not result in the treaty of support that the crown desired. Instead, each colony made the best deal it could with individual Iroquois leaders. Weiser was able to negotiate one of the more successful, in which some lower-level chiefs deeded to the colony most of the land remaining in present-day Pennsylvania, including the southwestern part, still claimed by Virginia.
