"Bury the hatchet" is a North American English idiom meaning "to make peace". The phrase is an allusion to the figurative or literal practice of putting away weapons at the cessation of hostilities among or by Indigenous peoples of the Americas in the Eastern United States and Canada.
It specifically concerns the formation of the Iroquois Confederacy[1][failed verification] and in Iroquois custom in general. Weapons were to be buried or otherwise cached in time of peace. Europeans first became aware of such a ceremony in 1644:[2][3]
"A translation of Thwaites' monumental work Jesuit Relations, 1644, suggests the practice: "Proclaim that they wish to unite all the nations of the earth and to hurl the hatchet so far into the depths of the earth that it shall never again be seen in the future."
The practice existed long before European settlement of the Americas, though the phrase emerged in English by the 17th century.[1][3]
Great Tree of Peace (early 1400s) (Noted in P.L. 110-82 as "Iroquois Confederacy")...The Peacemaker sealed the treaty by symbolically burying weapons at the foot of a Great White Pine, or Great Tree of Peace, whose 5-needle clusters stood for the original 5 nations: Mohawk, Oneida, Onondaga, Cayuga and Seneca. The Hiawatha Belt is a visual record of the creation of the Haudenosaunee dating back to the early 1400s, with 5 symbols representing the 5 original Nations.
