ONONDAGA NATION TERRITORY (AP) — The Onondaga Nation has regained 1,000 acres (405 hectares) of its ancestral land in upstate New York, a tiny portion of the land members say was unjustly taken by the state beginning in the 18th century.

The heavily forested land is south of Syracuse and near the Onondaga’s federally recognized territory. The land, which includes headwaters of Onondaga Creek, was transferred by Honeywell International on Friday under a federal Superfund settlement related to the contamination of the environment, according to the Onondaga Nation.

The land is part of an expanse of 2.5 million acres (1 million hectares) in central New York the Onondagas say was taken over decades by New York beginning in 1788 through deceitful maneuvers that violated treaties and federal law.

Sid Hill, the Tadodaho, or chief, of the Onondaga Nation, said Monday they were grateful to federal and state officials for working with them to return “the first 1,000 acres of the 2.5 million acres of treaty-guaranteed land taken from us over the centuries.”

“This is a small but important step for us, and for the Indigenous land back movement across the United States,” Hill said in a prepared statement.
