Manuelito was also an advocate for western education for Navajo children, with his famous quote, “… My grandchildren, education is a ladder. After being relocated to Bosque Redondo, Manuelito was among the leaders who signed the 1868 treaty, ending a period of imprisonment in United States government internment camps and establishing a reservation for the Navajo.
For several years he led a group of warriors in resisting federal efforts to forcibly remove the Navajo people to Bosque Redondo, New Mexico via the Long Walk in 1864. Manuelito was a prominent Navajo leader who rallied his nation against the oppression of the United States military. He was Ashkii Diyinii ("Holy Boy"), Dahaana Baadaané ("Son-in-Law of Late Texan"), Hastiin Ch'ilhaajinii ("Man of the Black Plants Place") and as Nabááh Jiłtʼaa (War Chief, "Warrior Grabbed Enemy") to other Diné, and non-Navajo nicknamed him "Bullet Hole". As many Navajo, he was known by different names depending upon context. He was born to the Bit'ahnii or ″Folded Arms People Clan″, near the Bears Ears in southeastern Utah about 1818. Manuelito is the diminutive form of the name Manuel, the Iberian variant of the name Immanuel Manuelito roughly translates to Little Immanuel.
Chief Manuelito or Hastiin Chʼil Haajiní ("Sir Black Reeds", "Man of the Black Plants Place") (1818–1893) was one of the principal headmen of the Diné people before, during and after the Long Walk Period.
