The Santa Fe Fiesta and the Inter-Tribal Indian Ceremonial are two of the major cultural events held annually in New Mexico, both involving substantial participation by the Indian population of the state and region. The older of these, the Fiesta, originated in 1712 when the Spanish governor, the Marqués of Pañuela, set aside a day in September to commemorate the reconquest of the province by Don Diego de Vargas. Since 1919, the festival has been held annually and has increasingly become a celebration of traditional New Mexican culture and the varied ethnicities of its population. The Inter-Tribal Indian Ceremonial of Gallup, New Mexico, was organized by local businessmen and Indian traders in 1922 for "the encouragement of Indian arts and crafts and the education of whites to the beauties of Indian life" and for the "perpetuation of the dances, traditions and customs of Indian life." The H. O. Hanson Photograph Collection contains 34 large format (8x10") black and white prints, including sixteen images of the Inter-Tribal Ceremonial at Gallup, 1953 and 1954, four images of the Jemez Pueblo, and nine images of the Santa Fe Fiesta, 1952 and 1953. Hanson has not been further identified, but he may have worked for the Bureau of Indian Affairs.
