This work shows an American Indian identified as Soi-En-Ga-Rah-Ta, or "King Hendrick." Soi-En-Ga-Rah-Ta was an Iroquois League chief born around 1677, who became a prominent leader by the early 1700s. He is sometimes referred to as "King of the Mohawk, " and traveled to Great Britain in 1710 as a representative of the Six Nations, comprising the Mohawk, Onondaga, Oneida, Cayuga, Seneca and Tuscarora peoples. He was killed in combat during the French and Indian War in September 1755, and was remembered as a great orator and spirited leader.
