Window Rock is the seat of government and capital of the Navajo Nation, the largest territory of a sovereign Native American nation in North America. Window Rock contains the Navajo Nation Council, the Navajo Nation Zoological and Botanical Park, as well as the Navajo Nation World War II Memorial. Window Rock's population was 2,712 at the 2010 census.Until 1936, the area was sparsely populated and known only by its ceremonial name Niʼ Ałníiʼgi. John Collier, Commissioner of Indian Affairs, chose the site to establish the seat of the Navajo Central Agency. His proposal to make the ceremonial name the official name met with resistance and Navajos soon ridiculed it as "ni ałnííʼgóó".Due to this, the name of the major local landmark, the rock-with-hole-through-it was chosen and rendered in English as "Window Rock".As of the census of 2000, there were 3,059 people, 876 households, and 713 families residing in the CDP.
