Land Acknowledgement: Cornell University is located on the traditional homelands of the Gayogo̱hó:nǫɁ (the Cayuga Nation). The Gayogo̱hó:nǫɁ are members of the Haudenosaunee Confederacy, an alliance of six sovereign Nations with a historic and contemporary presence on this land. The Confederacy precedes the establishment of Cornell University, New York state, and the United States of America. We acknowledge the painful history of Gayogo̱hó:nǫɁ dispossession, and honor the ongoing connection of Gayogo̱hó:nǫɁ people, past and present, to these lands and waters.
