WASHINGTON, D.C. - A Creek Nation delegation was in Washington, D.C. Monday for the unveiling of a new display featuring the tribe's 1790 Treaty of New York.

The treaty is a part of the Smithsonian's National Museum of the American Indian Nation to Nation Treaties exhibit.

The 1790 Treaty of New York was the first treaty between the Muscogee (Creek) Nation and the newly formed U.S. government.

"This is a historic moment recognizing the relationship we've had with the U.S. for a number of centuries.  The 1790 Treaty of New York is a living testament of what our ancestors accomplished, endured and negotiated for the well-being of the Muscogee (Creek) people and the Mvskoke way of life," said Muscogee Nation Cultural Center and Archives Interim Director Justin Giles.

Creek Nation officials said the document was signed to create "perpetual peace and friendship" between the U.S. and the Creek Nation.
