Bury the hatchet is an American English idiom meaning "to make peace". The phrase is an allusion to the figurative or literal practice of putting away the tomahawk at the cessation of hostilities among or by Native Americans in the Eastern United States, specifically concerning the formation of the Iroquois Confederacy and in Iroquois custom in general. Weapons were to be buried or otherwise cached in time of peace.
The first mention of the practice in English is to an actual hatchet-burying ceremony. Years before he gained notoriety for presiding over the Salem witch trials, Samuel Sewall wrote in 1680, "I write to you in one [letter] of the Mischief the Mohawks did; which occasioned Major Pynchon's goeing to Albany, where meeting with the Sachem the[y] came to an agreement and buried two Axes in the Ground; one for English another for themselves; which ceremony to them is more significant & binding than all Articles of Peace[,] the hatchet being a principal weapon with them."
The Treaty of Hopewell, signed by Col. Benjamin Hawkins, Gen. Andrew Pickens and Headman McIntosh, in Keowee, South Carolina in 1795 established the boundary of the Cherokee Nation, and made use of the phrase "bury the hatchet". Article 13 reads, in part, "The hatchet shall be forever buried, and the peace given by the United States, and friendship re-established between the said states on the one part, and all the Cherokees on the other, shall be universal; and the contracting parties shall use their utmost endeavors to maintain the peace given as aforesaid, and friendship re-established."
The Burying the Hatchet ceremony happened in Nova Scotia on June 25, 1761. It ended more than seventy-five years of war between the British and the Mi'kmaq.
Exactly 50 years after the Battle of Little Bighorn, White Bull, a Sioux Indian Chief, and General Edward Settle Godfrey buried the hatchet in the Tomb of the Unknown Soldier at Garryowen, Montana. It was near this site that Custer divided his forces and began his attack against the Sioux, Arapahoe and Cheyenne that were camped within the Valley of the Little Bighorn.
