McKenney took office in 1816 and shortly thereafter began to plan an archive which would house Indian memorabilia. In the winter of 1821-22, a large delegation of Indians including representatives of Pawnee, Sauk, Fox, Menominee, Miami, Sioux, and Chippewa tribes came to Washington to see President Monroe. McKenney took advantage of this opportune time to record their likenesses, commissioning Charles Bird King to paint their portraits. To these, more paintings were added in the years following, many done in the field. This yielded an impressive gallery of Indian portraiture which became the centerpiece of the War Department collection of Indian culture and history. In 1830, McKenney was dismissed by President Jackson and began to plan for the publication of a portfolio of prints of these portraits. Working with James Hall, he added text, making the project a true collaboration.
